PHP - filemtime function error

Question

Hi i get this error when a cache script is included in my site..

Warning: filemtime() [function.filemtime]: stat failed for index.php in C:\xampp\htdocs\Content\content\cache.php on line 6

Here is the script:

<?php
class datemod{
    public $gmtime;
    function date($files,$dbtable,$url){
        foreach($files as $val){
            $mod=date('Y/m/d H:i:s',filemtime($val));
            $array[]=$mod;
        }
        $fmod=max($array);
        $result=mysql_query("SELECT DATE_FORMAT(pubdate,'%Y/%m/%d %H:%i:%s') AS pubdate FROM $dbtable WHERE url='$url'");
        while($row=@mysql_fetch_array($result,MYSQL_ASSOC)){
            $row[]=array('row'=>array_map('htmlspecialchars',$row));
            $pubdate=$row['pubdate'];
        }
        $maxmod=max($fmod,$pubdate);
        $this->gmtime=date('D, d M Y H:i:s T',strtotime($maxmod));
    }
    function cache($gmtime){
        if(isset($_SERVER['HTTP_IF_MODIFIED_SINCE'])||isset($_SERVER['HTTP_IF_NONE_MATCH'])){
            if($_SERVER['HTTP_IF_MODIFIED_SINCE']==$gmtime){
                header('Status:304 Not Modified',true,304);
                exit();
            }
        }
        header("Last-Modified:$gmtime");
    }
}
?>

I cant seem to find whats wrong with it.. any help?

Could we see how the function is being called? A common mistake is calling filemtime() on a directory not file. — Flipper

The warning is triggered because there is no file index.php in the current dir (can be retrieved using getcwd())

It means that either file passed to filemtime() doesn't exist, or the program doesn't have permission to access its attributes.

Maybe begin by displaying or logging $val to see if it is what is expected. If all looks well there, then check the file permissions, including of every directory in the path.
