note 22383 added to function.file-exists

I've run into a problem, if i'm checking to see if a particular page on a web site exsits but when I check it, it tells me that the page exsits even though it dosn't. I think its because the web site sends you to a page that displays the 404 Error but what I'm asking is, is there a way of getting around that? -- http://www.php.net/manual/en/function.file-exists.php http://master.php.net/manage/user-notes.php?action=edit+22383 http://master.php.net/manage/user-notes.php?action=delete+22383 http://master.php.net/manage/user-notes.php?action=reject+22383
