How can I use PHP in my formhandler to see if image file entered into form is already in my filesystem

Question

Here is the code I have for that, but it never returns true.

    $image = $_FILES['image'];

    $filename = $image['name'];
    $filepathname = "/$membername/"."$filename";

    if (file_exists($filepathname)) {
       throw new Exception('Image already exists');
    }

Also you don't want to use user-supplied values directly for any path operations. Filter, at least `basename`. — mario, Sep 04 '12 at 23:48
Why do you think it should return true for you? Does `file_exists($knownExistingFilename)` return true? Does `knownExistingFilename` match the value of `filepathname` above? — Explosion Pills, Sep 05 '12 at 00:46

Does "$membername" contain the $_SERVER['DOCUMENT_ROOT'] path?

read more @ PHP's file_exists() will not work for me?

(if it does contain the $_SERVER['DOCUMENT_ROOT'] then you may want to check the file permission - assuming that you are using LAMP)
