note 22193 added to function.preg-match

To avoid the double escaping you can also just use single quotes, only it prevents from inserting variable data since '$foo' is interpreted as string $foo and not variable $foo. preg_match('/^[$oi]$/', $foo, $matches); Won't look for variable $oi but one of the three characters $, o or i. -- Simon -- http://www.php.net/manual/en/function.preg-match.php http://master.php.net/manage/user-notes.php?action=edit+22193 http://master.php.net/manage/user-notes.php?action=delete+22193 http://master.php.net/manage/user-notes.php?action=reject+22193
