problema cancellazione file

[whisher]

Ciao.
Prova questo.

<?php 
    $file_array = array();
    $handle = opendir('../data/cmnt/');
    while (false !== ($file = readdir($handle)))
    {
        if ($file != "." && $file != "..") 
        {
             $file_array[] =  $file;
        }
    }

    foreach($file_array as $files) 
    {
           if(substr(strrchr($files, "."), 1)=="php")
        {
                 copy($files, "backup/".$files);
                    unlink($files);
        }
    }
?>
