int preg_match( string $pattern, string $subject, return string[int] & $matches = NULL, int $offset = 0)

int preg_match_all(
        string $pattern,

        string $subject,

        return string[int][int] & $matches = NULL,

        int $flags = 1,

        int $offset = 0)

BUG: if the PREG_OFFSET_CAPTURE flag is used then the resulting structure of the $matches array is array[int][int][int]mixed where the elements mixed are strings and integers. PHPLint cannot support such a variability of types, so this prototype only accounts for the most common case in which the PREG_OFFSET_CAPTURE isn't used.
Remember that the possible flags combinations are:
PREG_PATTERN_ORDER (the default if no flags at all)
PREG_PATTERN_ORDER|PREG_OFFSET_CAPTURE
PREG_SET_ORDER
PREG_SET_ORDER|PREG_OFFSET_CAPTURE

string preg_replace(
        mixed $regex,

mixed[] preg_split( string $pattern, string $subject, ...)

string preg_quote( string $str, string $delim_char)

mixed[] preg_grep( string $regex, mixed[] $input)

int preg_last_error()
