By assigning a name to a capturing group, you can easily reference it by name. (?P<name>group)
captures the match of group into the backreference "name". You can reference the contents
of the group with the numbered backreference or the named backreference
<?php
preg_match_all('|(a)(?P<x>b)(?P<y>c)(d)|','abcdefgabcdefg',$sub);
echo $sub[2][0]; //b
echo '<br />';
echo $sub['y'][0]; //c
?>
