Delete all files from a folder using PHP

Dear friends,
In some cases we will be forced to clear the contents of some server folders. Use the code given below.

//Code starts here

<?php

$files = glob('HUP/*'); // get all file names
foreach($files as $file)
{ // iterate through the files in the folder
  if(is_file($file))
    unlink($file); // delete file
}
?>
