How to read this form wiht php lang, Great Thanks

$destDir = '/mydir/'; // Where we will put the files

for ($i = 0; $i < 5; $i++) {
  if (!$_FILES['Filedata']['error'][$i]) { // only process files that are present and were uploaded successfully
    move_uploaded_file($_FILES['Filedata']['tmp_name'][$i],$destDir.$_FILES['Filedata']['tmp_name'][$i]);
  }
}

The files are now in $destDir.
