admin.php

<?php

$dir = "Gum_files/";

if (is_dir($dir)) {
   if ($dh = opendir($dir)) {
      while (($file = readdir($dh)) !== false) {
             echo "File: ".$file." - <a href=\"admin.php?delete=".$file."\" >Cencella</a> ";
        }
        closedir($dh);
    }
}

if($_GET['delete']!=""){
$nomefile = $dir.$_GET['delete'];
unlink($nomefile);
}

?>

prova così dovrebbe funzionare
