You can use this function as a general if nothing from the array is found in the string append something to it.

function httpify($link, $append = 'http://', $allowed = array('http://', 'https://')){

  $found = false;
  foreach($allowed as $protocol)
    if(strpos($link, $protocol) !== 0)
      $found = true;

  if($found)
    return $link;
  return $append.$link;
}
