Description:
------------
PHP4.3.6RC3 Actually. Previously reported for different versions; #21410, #16830

Will *at seemingly random* times produce incorrect behavior.

IE:
"./images/members/admin.jpg" does not exist, but for some reason it returns true.

Apologies if this has been corrected in later versions, I can't tell - my ISP is evil.

Reproduce code:
---------------
function pictureExists($path, $extensions) {

    for ($i=0;$i<=count($extensions);$i++) {
		print $path . "." . $extensions[$i];
		phpinfo();
		print file_exists($path . "." . $extensions[$i]);
		print true;
        if (file_exists($path . "." . $extensions[$i]) == true) {
            return "." . $extensions[$i];
        }
    }

    return false;
}

$path = "./images/members/admin";
$exts[] = "jpg";
pictureExists($path,$exts);

Expected result:
----------------
return true


Actual result:
--------------
return false.
