* The pattern to search for, as a string. *

* The input string. *

* If matches is provided, then it is filled with * the results of search. $matches[0] will contain the * text that matched the full pattern, $matches[1] * will have the text that matched the first captured parenthesized * subpattern, and so on. *

* flags can be the following flag: * PREG_OFFSET_CAPTURE *

* If this flag is passed, for every occurring match the appendant string * offset will also be returned. Note that this changes the value of * matches into an array where every element is an * array consisting of the matched string at offset 0 * and its string offset into subject at offset 1. *

 * 
 * 

* The above example will output: *

 * Array
 * (
 *     [0] => Array
 *         (
 *             [0] => foobarbaz
 *             [1] => 0
 *         )
 *
 *     [1] => Array
 *         (
 *             [0] => foo
 *             [1] => 0
 *         )
 *
 *     [2] => Array
 *         (
 *             [0] => bar
 *             [1] => 3
 *         )
 *
 *     [3] => Array
 *         (
 *             [0] => baz
 *             [1] => 6
 *         )
 *
 * )
 * 

*

* If this flag is passed, unmatched subpatterns are reported as NULL; * otherwise they are reported as an empty string. *

 * 
 * 

* The above example will output: *

 * array(4) {
 *   [0]=>
 *   string(2) "ac"
 *   [1]=>
 *   string(1) "a"
 *   [2]=>
 *   string(0) ""
 *   [3]=>
 *   string(1) "c"
 * }
 * array(4) {
 *   [0]=>
 *   string(2) "ac"
 *   [1]=>
 *   string(1) "a"
 *   [2]=>
 *   NULL
 *   [3]=>
 *   string(1) "c"
 * }
 * 

*

* Normally, the search starts from the beginning of the subject string. * The optional parameter offset can be used to * specify the alternate place from which to start the search (in bytes). *

* Using offset is not equivalent to passing * substr($subject, $offset) to * preg_match in place of the subject string, * because pattern can contain assertions such as * ^, $ or * (?<=x). Compare: *

 * $subject = "abcdef";
 * $pattern = \'/^def/\';
 * preg_match($pattern, $subject, $matches, PREG_OFFSET_CAPTURE, 3);
 * print_r($matches);
 * 

 * Array
 * (
 * )
 * 

* while this example *

* will produce *

 * Array
 * (
 *     [0] => Array
 *         (
 *             [0] => def
 *             [1] => 0
 *         )
 * )
 * 

* The pattern to search for, as a string. *

* The input string. *

* Array of all matches in multi-dimensional array ordered according to flags. *

* Can be a combination of the following flags (note that it doesn\'t make * sense to use PREG_PATTERN_ORDER together with * PREG_SET_ORDER): * PREG_PATTERN_ORDER *
* Orders results so that $matches[0] is an array of full * pattern matches, $matches[1] is an array of strings matched by * the first parenthesized subpattern, and so on. *

* Normally, the search starts from the beginning of the subject string. * The optional parameter offset can be used to * specify the alternate place from which to start the search (in bytes). *

* Using offset is not equivalent to passing * substr($subject, $offset) to * preg_match_all in place of the subject string, * because pattern can contain assertions such as * ^, $ or * (?<=x). See preg_match * for examples. *

* * preg_match_all("|]+>(.*)]+>|U", * "example: this is a test", * $out, PREG_PATTERN_ORDER); * echo $out[0][0] . ", " . $out[0][1] . "\\n"; * echo $out[1][0] . ", " . $out[1][1] . "\\n"; * * The above example will output:

 * example: , this is a test
 * example: , this is a test
 * 

* So, $out[0] contains array of strings that matched full pattern, * and $out[1] contains array of strings enclosed by tags. *

* The pattern to search for. It can be either a string or an array with * strings. *

* Several PCRE modifiers * are also available, including the deprecated \'e\' * (PREG_REPLACE_EVAL), which is specific to this function. *

* The string or an array with strings to replace. If this parameter is a * string and the pattern parameter is an array, * all patterns will be replaced by that string. If both * pattern and replacement * parameters are arrays, each pattern will be * replaced by the replacement counterpart. If * there are fewer elements in the replacement * array than in the pattern array, any extra * patterns will be replaced by an empty string. *

* replacement may contain references of the form * \\\\n or (since PHP 4.0.4) * $n, with the latter form * being the preferred one. Every such reference will be replaced by the text * captured by the n\'th parenthesized pattern. * n can be from 0 to 99, and * \\\\0 or $0 refers to the text matched * by the whole pattern. Opening parentheses are counted from left to right * (starting from 1) to obtain the number of the capturing subpattern. * To use backslash in replacement, it must be doubled * ("\\\\\\\\" PHP string). *

* When working with a replacement pattern where a backreference is * immediately followed by another number (i.e.: placing a literal number * immediately after a matched pattern), you cannot use the familiar * \\\\1 notation for your backreference. * \\\\11, for example, would confuse * preg_replace since it does not know whether you * want the \\\\1 backreference followed by a literal * 1, or the \\\\11 backreference * followed by nothing. In this case the solution is to use * \\${1}1. This creates an isolated * $1 backreference, leaving the 1 * as a literal. *

* When using the deprecated e modifier, this function escapes * some characters (namely \', ", * \\ and NULL) in the strings that replace the * backreferences. This is done to ensure that no syntax errors arise * from backreference usage with either single or double quotes (e.g. * \'strlen(\\\'$1\\\')+strlen("$2")\'). Make sure you are * aware of PHP\'s string * syntax to know exactly how the interpreted string will look. *

* The string or an array with strings to search and replace. *

* If subject is an array, then the search and * replace is performed on every entry of subject, * and the return value is an array as well. *

* The maximum possible replacements for each pattern in each * subject string. Defaults to * -1 (no limit). *
