function generaterandomstring($length = 10) {
  $characters = '0123456789abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz';
  $characterslength = strlen($characters);
  $randomstring = '';
   for ($i = 0; $i < $length; $i++) {
  $randomstring .= $characters[rand(0, $characterslength - 1)];
   }
   return $randomstring;
}
