 PHPLint Support for phpDocumentor

Last updated: 2013-12-29

PHPLint provides support for the phpDocumentor's DocBlock comments (www.phpdoc.org). PHPLint parses and gathers the informations found inside a DocBlock and merges these informations with those gathered from the PHP source and the PHPLint meta-code.

From a DocBlock, PHPLint acquires not only textual descriptions, but it acquires also the types of variables, function arguments and returned values.

What is a DocBlock

Constants, variables, functions, classes, class constants, properties and methods can be preceded by a multi-line comment properly formatted. The symbol /** marks the beginning of the DocBlock:

/**   Two asterisks after the slash mark the beginning of the DocBlock.  */

Every line of the DocBlock may begin with an optional asterisk "*", which is ignored and discarded:

 * The asterisk at the beginning of every line has only an
 * aesthetical purpose and, if present, is ignored and will
 * not be rendered in the generated document.

Every line, apart from the asterisk and the possible surrounding spaces, is the content of the DocBlock. The structure of a DocBlock consists of three sections: the short description, the long description and the line tags, in this order.

 * The first sentence is the short description. Any text that
 * follows up to the first line tag is the long description.
 * The short description should be short, possibly incomplete
 * but meaningful, usually not longer than one line of text.
 * @param int $i  A line that begins with @ is a line tag.
 * @return void  And this is another line tag.

The short description starts at the first non-empty line and spans up to the first empty line, the end of the DocBlock or the first period not included inside a word. If the short description so determined results to be more than 3 lines long, only the first line is taken. If the short description is terminated by a period, the period itself is removed.

All the text between the short description and the first line tag or the end of the DocBlock is the long description.

The short description, the long description and the descriptive text allowed in some of the line tags can contain a subset of the HTML entities as listed below:

<b> <i> <code> <br> <kbd> <p> <pre> <ul> <ol> <li> <samp> <var>

The last two entities are not real HTML entities, but special tags defined by phpDocumentor; these are passed unchanged but are ignored by WEB browsers. Currently PHPLint does not allow upper-case letter, nor it allows spaces inside the tags, so take care to write them exactly as indicated here otherwise they would be rendered literally. Moreover, PHPLint checks for proper usage of these entities, and raises an error on unclosed tags, wrong nesting, badly formed punctuated lists, etc.

The following tag and special sequences are additions of PHPLint and may be incompatible with other documentation systems:

Single Unicode characters can be entered as "&#123;" in decimal notation, or as "&#x1ab;" in hexadecimal notation. For example, the asterisk is &#42;.

Others tag specific of PHPLint:

<sub> <sup> <blockquote> <center>

These tags, and only these, can be used to format the text of the long description. Any other entity or special character including < > & gets rendered literally (i.e. < is converted to &lt; and so on).

The text enclosed between <pre> and </pre> is always rendered literally.

The line tags are all the lines with a leading "@" (extra spaces and tabulations between the asterisk and the "@" are ignored). The first line tag found opens the line tags section of the DocBlock.

What can be commented with a DocBlock

Packages. The word package here is intended in the sense of PHPLint packages, that is simply a file containing PHP code. The name of the package as set with the @package line tag is simply used by PHPLint to give a title to the generated document. If missing, the title of the document is the base name of the file.

The first DocBlock encountered that contains the @package line tag is assumed to be the comment about the package itself; in other words, this line tag is mandatory for DocBlocks that comment a package.

Constants. Are constants all the items defined with the define() statement. PHP 5.3 also introduces the const statement with the same syntax of the class constants: also these constants can be documented with a DocBlock.

Global variables. It is unusual, but there are cases in which having global variables may be useful. Only global variables can have a DocBlock; local variables cannot.

Functions. DocBlocks for functions may declare the complete signature of the function, including all the formal arguments and the return value. Exceptions inherited are also automatically reported.

Interfaces, abstract classes and concrete classes can have their own DocBlock.

Class constants, properties and methods can have their own DocBlock.

The other elements of the source that cannot be documented:
the namespace statement,
the use statement,
the declare statement,
the include, include_once, require statements.


The following source illustrates the main features of a DocBlock.


 * PhpDoc test source.
 *  This is a <i>package description</i>. This source does
 *  nothing useful, it is intended only to illustrate the features of the
 *  phpDocumentor and how a DocBlock looks like.
 * @package PhpDocTest
 * @author  Umberto Salsi <phplint@icosaedro.it>
 * @version 1.0
 * @deprecated  Do not use this package, it is completely useless!

/*. require_module 'standard'; .*/

 * Popular approximation of the greek pi.
define("POPULAR_PI", 3.14);

 *  Last error code found.
$last_error = 0;

 *  Search a name inside an array of names. The long description starts
 *  with this second sentence.  Both the short description and the long
 *  description are optionals.
 *  @param string $name    Name of the item we are looking for.
 *  @param string[int] $arr
 *           List of items. Note that we have indicated both the type of the
 *           index (int) and the type of the elements (string):
 *           this is a PHPLint extension that works also for phpDocumentor.
 * @return int   The index of the element found, or -1 if not found.
function searchName($name, $arr)
	foreach($arr as $k => $v)
		if( $v === $name )
			return $k;
	return -1;


Also the PHP 4 classes can be documented: properties and methods can have a visibility attribute, and methods can have also the static and the final attributes:

/*. require_module 'pgsql'; .*/

 *  Example of class to access to the PostgreSQL DB.
 *  @author Umberto Salsi <phplint@icosaedro.it>
class DBAccess {

     *  Name of the current DB
     *  @var string
     *  @access public
    var $db_name;

     *  Current connection to the DB
     *  @var resource
     *  @access private
    var $db_conn;

     *  Opens the connection with the given DB
     *  @access public
     *  @param string $db_name   Name of the DB
     *  @return void
    function DBAccess($db_name)
        $this->db_conn = pg_connect("dbname=$db_name");
        if( $this->db_conn === FALSE )
            die("connection to $db_name failed");
        $this->db_name = $db_name;

    /* ... */

PHP 5 classes already have their own attributes keywords abstract final static private protected public built-in, and these keywords must be used instead of the DocBlock tags. Also PHP 5 class constants can be documented:

abstract class DBLogger
    extends GenericDB
    implements Logger
     *  Timeout for any operation on the DB (s)
    const TIMEOUT = 0.5;

     *  Commenting a method in PHP 5. Note that the @access
     *  tag cannot be used since PHP 5 already has its own
     *  keyword.
     *  @param string $query
     *  @return bool
    public abstract function testTimeout($query);

    /* ... */

Abstract classes and interfaces can be commented with DocBlocks as you can expect:

 *  Documenting an interface class
interface TreeInterface
     *  Constants are always public. No type declaration is
     *  required, as their value already says all.
    const ROOT_NODE_LEVEL = 0;

     *  Methods are always abstract, public and non-final.
     *  @param mixed $key
     *  @return void
    function addNode($key);

Supported line tags

The syntax of every line tag is described with the aid of these elements:

WORD is any sequence of characters not including spaces, tabulations an new-lines. WORDs are rendered literally.

$VAR is the name of a variable. Note that the dollar sign is required.

TEXT is any text, possibly spanning on several lines up to the next line tag or the end of the DocBlock. A TEXT is rendered literally.

DESCR is an HTML text, and the subset of tags already listed for the long description are allowed. The DESCR can span several lines up to the next line tag or the end of the DocBlock. A DESCR enclosed between square parenthesis [DESCR] is optional.

The following table summarizes all the available line tags, their syntax, and the context where they are legal:

Note 1. PHP 5 already has the attributes abstract final private protected public static. These keywords must be used instead of the corresponding phpDocumentor line tags.

Note 2. The @throws line tag is explained below in detail.

The supported TYPEs are described in the next paragraph.

PHPLint raises a notice if a line tags is used in the wrong context, for example @var in a function description.

PHPLint raises a warning if a DocBlock omits to declare the type of a variable, function, argument, property or method and this type cannot be guessed from the code.


All the basic PHP types are supported, with the addition of void. The general syntax in EBNF format is:

 TYPE = name | array_old_syntax | array_new_syntax;
 array_old_syntax = "array" [ index {index} [name] ];
 array_new_syntax = name index {index};
 index = "[]" | "[int]" | "[string]";
 name = "void"     | "bool"   | "boolean" | "int" | "integer"
      | "float"    | "double" | "real"    | "string"
      | "resource" | "mixed"  | "object"  | class_name
      | "FALSE"    | "NULL";
 class_name = ["\\"] identifier {"\\" identifier};

(For the keyword FALSE and NULL, that are not really types, see the discussion below).

The following table summarizes the allowed types and their meaning:

Type Description
void Functions and methods that do not return a value are declared to return a value of this dummy type.
bool or boolean A boolean value, either FALSE or TRUE. 0 and 1 are numbers in PHPLint and cannot be used in place of the boolean values.
int or integer An integer number.
float or double or real A floating point number.
string A string of bytes. Variables of this type can also evaluate to NULL under PHPLint.
array[K]E Array with keys of type K and elements of type E. Variables of this type can also evaluate to NULL under PHPLint.
resource Typically an opened file, or a network socket. Variables of this type can also evaluate to NULL under PHPLint.
object Generic object. Variables of this type can also evaluate to NULL under PHPLint.
CLASS_NAME An object of the specified class. Variables of this type can also evaluate to NULL under PHPLint.
mixed A variable of this type is a generic container of any type of value. Variables of this type can also evaluate to NULL under PHPLint. You should avoid mixed variables, or use them with care, because there is very little you can do with variables of such type under PHPLint.

An array can be described including the type of the index and the type of the elements using the old PHPLint syntax:

or the new, more concise, but perfectly equivalent PHPLint syntax below:

being K the type of the key (int or string) and E the type of the elements (all the elements must be of the same type).

This is an extension of the array type already supported by phpDocumentor. Some examples:

Several ways to define an array type
Long form Short form Description
array mixed[] index can be both integers and strings, elements mixed (avoid)
array[] mixed[] index can be both integers and strings, elements mixed (avoid)
array[int]string string[int] array of strings with int index
array[int][int]float float[int][int] matrix of floating-point numbers
array[string]it\icosaedro\bignumbers\Bigint it\icosaedro\bignumbers\Bigint[string] associative array of big integer numbers
array[]SomeClass SomeClass[] array of objects of the class SomeClass,
the keys can be both integer numbers and strings (avoid)
array[int]SomeClass SomeClass[int] array of objects of the class SomeClass,
the keys are integer numbers

Some functions and methods can return values of different types that can be listed separated by a vertical bar. Many functions of the standard library can return some result or FALSE on error. For example fopen() can return either a resource or the FALSE value. This practice is discouraged by PHPLint, but it is tolerated; in this case PHPLint keeps only the first type, then the remaining types are parsed but ignored. Example:

 *  Opens my data file
 *  @return resource|FALSE
function my_fopen()
    return fopen("data.txt", "r");

Note that PHPLint allows to indicate the value FALSE in place of the correct type boolean just to support this common practice. The Tutorial expands this topic with several practical examples. Please, in new software you write (or at least, if it is intended to be validated by PHPLint) try to choose among the alternatives indicated there.

Literal arrays

In PHP, literal arrays can be defined through the array() constructor. PHPLint parses accurately the literal arrays in order to guess their type (both index and elements). The manual of PHPLint explains in detail how these guesses are made. Basically, if no keys are specified, the type of the index default to int. The type of the elements is the type of the expression giving the value of the elements. For example:

Literal array Guessed type
array() mixed[]
array( array( ) ) mixed[int][]
array( "a" => array( ) ) mixed[string][]
array("AA", "BB") string[int]
array(0=>"AA", 1=>"BB") string[int]
array("a"=>"AA", "b"=>"BB") string[string]
array( new SOME_CLASS() ) SOME_CLASS[int]
array("a"=>array(1.0,0.0), "b"=>array(0.0,1.0)) float[string][int]
/*. (float[int]) .*/ array() float[int]
array( /*. (float[int]) .*/ array() ) float[int][int]

Note that PHPLint encounters a difficulty when the literal array is empty, because no keys nor elements are available and the resulting type is an array of unspecified structure (PHPLint will display that as unknown[unknown]). Such undefined type is likely to produce an error if it is assigned to some variable or passed by value to a function. PHPLint allows to add a formal typecast in fromt to the empty array. The formal typecast /*.(T).*/ tells to PHPLint which is the expected structure of the empty array.

The same holds when the NULL value is involved in an expression: NULL is a special value that is assignment-compatible with every array, but it cannot provide to PHPLint any information about the real structure of the array.
In these cases the correct type should be indicated through a formal typecast, like in these examples:

 *  List of names, initially empty.
 *  Here using PHPLint formal type-cast.
$names = /*. (string[int]) .*/ array();

 *  List of names, initially NULL.
 *  Here using phpDocumentor line tag.
 *  @global string[int] $names2
$names2 = NULL;

 *  List of names, initially NULL
 *  When a @global or @var line tag is used, the type specified must match
 *  the type of the expression.  In this case, since the exact type of the
 *  array is provided by this DocBlock, no ambiguities arises an the formal
 *  type-cast is not required.
 *  @global string[int] $names3
$names3 = NULL;

 *  Matrix of coefficients, initially empty
$m = /*. (float[int][int]) .*/ array();

 *  Prints a list of names. This function requires an array of a well
 *  defined structure.
 * @param string[int] $a  List of names.
 * @return void
function print_names($a)
    echo count($a), " names in list:\n";
    for($i=0; $i<count($a); $i++)
        echo $a[$i], "\n";

print_names( array( "Foo", "Bar" ) );
 *  Here the type of the actual argument is correctly guessed by PHPLint
 *  to be string[int], which matches exactly the type of the formal
 *  argument $a.

print_names( /*. (string[int]) .*/ array() );
 *  Note the empty list and the formal typecast.  Without this formal
 *  type-cast PHPLint would raise an error because the type of the array
 *  unknown[unknown] would be incompatible with any passed actual value.

print_names( NULL );
 *  NULL is assignment-compatible with the type of the formal argument,
 *  so no format typecast is required. For the record, since count(NULL)
 *  gives 0, nothing will be printed by the function.

The @throws line tag

The @throws line tag is an important extension of PHPLint to the format of the DocBlock, but it is not officially supported by phpDocumentor. phpDocumentor simply reports this line tag verbatim. Instead, PHPLint provides full support for PHP 5 exceptions, including their declaration inside the DocBlock.

The @throws WORD [DESCR] line tag allows to declare an exception the function or the method may throw, where WORD is the name of the exception and DESCR describes the conditions that causes this exception to be thrown:

 *  Return the size of the file. On 32-bit systems, this function
 *  returns the correct value also for files whose size is up to 4 GB.
 *  @param string $filename  Path of the file.
 *  @return float  Size of the file (bytes). Being a float, this value
 *                 may be greater than the maximum allowed for int.
 *  @throws ErrorException  If an error occurs accessing the file.
function BigFileSize($filename)
    $size = @filesize($filename);
    if( $size === FALSE )
        throw new ErrorException($php_errormsg);
    if( $size >= 0 )
        return (float) $size;
        return (float) $size + 2.0 * (1.0 + PHP_INT_MAX);

interface MyCollection {

     *  Return the element of the given index in the list.
     *  @param int $index  Index of the element.
     *  @return mixed      The element.
     *  @throws OutOfBoundException  If the $index is out of bound.
     *  @throws ErrorException   Implementing methods may also throw this,
     *                           depending on the specific code that will
     *                           implement this method.
    function getElement($index);


All the checked exceptions a function or method may throw must be declared. It is allowed to add also unchecked exceptions, but these exceptions are reported in the generated documentation only if a descriptive text is also provided; if no descriptive text is provided, the declaration of the unchecked exception is parsed but it is otherwise completely ignored.

The programmer may still add more exceptions the are still not thrown, but that might thrown later in some overriding or implementing method. In fact, as explained in more details in the PHPLint manual, the list of thrown checked exceptions is part of the method contract that implementing and overriding methods must comply with. Basically, implementing and overriding methods can only throw the same checked exceptions the original method throws, or even more specialized exceptions derived from these. In other words, implementing and overriding methods cannot throw new, unrelated exceptions.

In the document generated by PHPLint Documentator, thrown exceptions are always listed in the order from more specialized ones to more general ones (that is, parent classes) so to suggest to the programmer the proper order of the catch() branches.

Namespaces and names resolution

ATTENTION! Namespaces are still not supported by the official phpDocumentor program, so what follows must be considered as an extension specific of PHPLint.

PHP 5.3 introduces the concept of namespaces with which, for example, the fully qualified name of a class consists of one or more identifiers separated by a back-slash character, like in this example: it\icosaedro\bignumbers\BigInt. To be more precise, we will use the following nomenclature with examples applied to the class above:

The fully qualified name (FQN) of the class is a sequence of identifiers separated by the back-slash character that univocally identify the item; you may think at it as the real, complete name of the class or function:


A qualified name is a sequence of two or more identifiers separated by the back-slash character, that may represent only part of a FQN:


The absolute name of the class is its FQN with a leading back-slash appended to it:


Proper name of the class if the last identifier of the FQN:


The namespace\ operator can be used as a shortland to reference an item which is reachable from the current namespace and the name so generated is considered absolute. For example, if the current namespace is it\icosaedro then namespace\bignumbers\BigInt is the absolute name of the intended item.

Incomplete names, that is qualified and bare identifiers, are also allowed but a special resolution algorithm has to be applied in order to recover the actual absolute name of the intended item. PHPLint applies the same resolution algorithm the PHP interpreter applies. The only difference is that PHPLint performs namespace resolution also in PHPLint meta-code and in DocBlocks.

Then the @param line tag, the @return line tag and the {@link} all can make reference to constants, functions and classes using fully qualified names, qualified names, and bare identifiers. Also the namespace\ operator and the use clauses are interpreted as usual.

There are only two restrictions to names that occurs in a DocBlock:

The name resolution is performed in the same context of the DocBlock, so using the same current namespace and the same list of use mappings. The following example illustrate the issue with two DocBlocks, the first appears before a namespace, and the second appears after the namespace:

 *  DocBlock outside the namespace. The namespace below declared the class
 *  BigInt and the function One.  To refer to the class BigInt we must use a
 *  fully qualified name, for example {@link \it\icosaedro\bignumbers\BigInt}
 *  because this DocBlock is still in global namespace.
 *  Unqualified names as {@link BigInt} and qualified names as {@link
 *  bignumbers\One()} DO NOT WORK and give an error because cannot be resolved
 *  in the context of this DocBlock, and because the `use' clauses below
 *  have a scope limited to their namespace.
 *  Now the mandatory @package line tag, as usual, to give a name to this
 *  package:
 *  @package it/icosaedro/bignumbers/BigInt

namespace it\icosaedro\bignumbers;

use it\icosaedro\bignumbers;

use it\icosaedro\bignumbers as BN;

class BigInt {
    # ...

 *  Quite useless function that returns a cached BigInt(0).
 *  @return BigInt
 *          Unqualified name here works, but also {@link bignumbers\BigInt}
 *          and {@link BN\BigInt} are allowed.
 *  @throws \Exception  Inherited from BigInt for this and that reason.
 *          Useless (but allowed) leading back-slash.
function Zero()
    static $zero = /*. (BigInt) .*/ NULL;
    if( $zero == NULL )
        $zero = new BigInt(0);
    return $zero;

And here is how a possible client package might use the package above:


require_once __DIR__ . "/../../bignumbers/BigInt.php";

namespace it\icosaedro\stats\Test;
use it\icosaedro\bignumbers\BigInt;
use it\icosaedro\bignumbers as BN;

 *  This package performs simple statistical calculations using
 *  big numbers from the {@link BigInt} class.
 *  @package it\icosaedro\stats\Test

 *  Calculates the arithmetic mean between {@link BigInt} numbers.  This link
 *  can be resolved using the first "use" clause.  With the second "use"
 *  clause we might also write {@link BN\BigInt} but it is mostly useful to
 *  build short names of non-class items like the {@link BN\Zero()} function.
 *  Without any "use" clause we would need to write the fully qualified name
 *  {@link \it\icosaedro\bignumbers\BigInt}.
 *  @param array[]BN\BigInt $a  One, two or more numbers.
 *     Illustrates how the second "use" clause can be used to
 *     resolve the name. A bare array[]BigInt would be sufficient
 *     because we have imported the class with the first "use".
 *  @return it\icosaedro\bignumbers\BigInt   The arithmetic mean.
 *     Here too, a bare BigInt would be sufficient.
function Mean($a)
    $n = count($a);
    $sum = $a[0];
    for( $i = 1; $i < $n; $i++ )
        $sum = $sum->add($a[$i]);
    return $sum->div( new BigInt($n) );

Summarizing, fully qualified, qualified and unqualified names of constants, functions and classes may appear in the {@link} in line tag and in the @param and @return line tags as class names, and in all these cases namespace resolution algorithm applies.

All the items parsed by PHPLint are reported in the generated document with their fully qualified names.

Namespaces declarations by themselves are not reported and cannot be documented with a DocBlock.

Supported inline tags

The sequence of characters {@ has a special meaning as it is the beginning of an inline tag. The general syntax of an inline tag is as follows:


Some inline tags may have one or more arguments separated by one or more spaces, tabulator characters or line feed; the general structure of an inline tag requiring arguments is a follows:

{@TAG ARG1 ARG2 ... ARGn}

Inline tags are allowed in the short description, in the long description, and in the descriptive text of line tags that have a descriptive text. Inline tags are not allowed, that is are passed verbatim, in any other location.

The inline tags PHPLint supports are listed below:

This tag allows to insert the sequence of characters {@ that would be otherwise forbidden because them are reserved to start an inline tag.
This tag allows to insert the sequence of characters */ that would be otherwise forbidden in a multi-line comment. It is mostly useful when a long chunk of code has to be inserted into the text.
{@link ITEM}
{@link ITEM text to be displayed}
{@link URL}
{@link URL text to be displayed}
This tag allows to insert an hypertextual link to some documented item (constant, variable, function, etc.) or to some generic resource available in Internet through an URL. ITEMs can be specified using their name, for example:

{@link M_PI}
inserts a reference to the constant M_PI.

{@link $varName}
inserts a reference to the global variable $varName. Note that the $ symbol is mandatory. Variables that are local to a function or method and formal arguments of function and method cannot be referenced.

{@link funcName()}
inserts a reference to the function funcName(). Note that the parentheses are mandatory as them allows to distinguish between constants and functions. You may also add specific arguments inside the parentheses, but still spaces are not allowed. For example you may write {@link tan(M_PI)}.

{@link SomeClass}
inserts a reference to the class or interface SomeClass.

{@link SomeClass::SOME_CONST}
inserts a reference to the class constant SomeClass::SOME_CONST.

{@link SomeClass::$aProperty}
inserts a reference to the property SomeClass::$aProperty.

{@link SomeClass::aMethod()}
inserts a reference to the method SomeClass::aMethod(). Between parentheses, you may enter some specific actual argument just like already explained for functions.

In DocBlocks related to a class, the class name itself can be omitted, so bringing to these shorter references:

{@link ::SOME_CONST}
inserts a reference to the class constant SOME_CONST defined inside the same class to which the DocBlock belongs.

{@link ::$aProperty}
inserts a reference to the property $aProperty defined inside the same class to which the DocBlock belongs.

{@link ::aMethod()}
inserts a reference to the method aMethod() defined inside the same class to which the DocBlock belongs.

The ITEMs that can be referenced are only those that are available in the current package, including imported standard modules (see require_module) and imported packages (see require_once). Instead, ITEMs that are not accessible from the current package cannot be referenced directly but, if really needed, a full URL or a relative path can be provided instead.

Private items cannot be referenced.

The {@link} inline tag also allows to insert links either to local file or to remote resources. To avoid URLs and file paths be confused with PHP documented items, URLs must always indicate the protocol used and file paths must always be indicated as relative to the directory of the current document file or as absolute path. For example:

{@link ftp://sources.company.com/myproject/package-1.0.zip}
{@link http://www.company.com/}
{@link mailto:bugs@company.com Please, send bug reports here}
{@link ./anotherPackage.htm}
{@link ../otherLib/otherPackage.htm}
{@link /home/Me/projects/myProject/index.htm}
{@link c:/php-lib/index.htm}

{@img URL}
This tag allows to insert an image. This tag is an extension specific of PHPLint and may be incompatible with other documentation systems.

Unsupported inline tags {@example} {@internal} {@inheritdoc} {@source} {@tutorial} are reported verbatim. Invalid inline tags are reported verbatim but signaled as errors.
