When you use meta-characters in the regular expression, avoid using them as delimiters. In
preference, do not use the meta-characters as delimiters at all.
Besides, you must not forget to escape the delimiter if it exists in the user text. The function
preg_quote permits to escape the delimiter if it exists in the user text.
<?php
$usertext=preg_quote($usertext,$delimiter);
?>
