Named capture in PHP using regex

Question

How can I use named capture with regex in PHP? Can anyone give me a working example?

Answer 1

Doesn't work with replace , only useful for match in php

$test="yet another test";  preg_match('/(?P<word>t[^s]+)/',$test,$matches);  var_dump($matches['word']); 

Answer 2

According documentation

PHP 5.2.2 introduced two alternative syntaxes (?<name>pattern) and (?'name'pattern)

So you'll get same result using:

<?php preg_match('/(?P<test>.+)/', $string, $matches);  // basic syntax preg_match('/(?<test>.+)/', $string, $matches);   // alternative preg_match("/(?'test'.+)/", $string, $matches);   // alternative
