note 20120 added to function.filemtime

I'm trying to get a mouseover that displays the date of last modification for the file being reference by the link. I keep getting stuck in passing the PHP variable to a javascript variable. Is there any way to do this? -- http://www.php.net/manual/en/function.filemtime.php http://master.php.net/manage/user-notes.php?action=edit+20120 http://master.php.net/manage/user-notes.php?action=delete+20120 http://master.php.net/manage/user-notes.php?action=reject+20120
