A small piece of PHP code problem

PHP Code

It seems wrong, I think of another way to compromise:

PHP Code

Such a regular can be obtained. /documents/medies/link_icon1.gif and. /documents/medies/link_icon.gif
So I want to replace it again. But the error:
Warning:preg_replace () [function.preg-replace]: Unknown modifier '/' in


What needs to get is link_icon1.gif and link_icon.gif. The previous: The/documents/medies/path is fixed.
What should I do?



------Solution--------------------
$s =join ("', '", $imgne);
$sql = "Update imgmulu set page_id = 101370 where img_name in ('". $s. "')";
