Deleting all files from a folder using PHP?

by 
$files = glob('path/to/temp/*'); // get all file names
foreach($files as $file){ // iterate files
  if(is_file($file)) {
    unlink($file); // delete file
  }
}

If you want to remove ‘hidden’ files like .htaccess, you have to use

$files = glob('path/to/temp/{,.}*', GLOB_BRACE);
