and if it contains , it execute my function : itsReddit()

maybe with preg match? or something like this?

Please i don't want a link for tutorial, i only need a php code for this, & THANKS soo much!

Answer 1

  if(strpos($your_link, 'reddit.com') !== FALSE) itsReddit();

Answer 2

$input = 'http://www.reddit.com/xxx/x/xxx';
if ( false!==stripos($input, 'reddit.com') ) {
  //itsReddit();
  echo 'reddit';
}

Or if you want to test if the host is reddit.com

$input = 'http://www.reddit.com/xxx/x/xxx';
$host = parse_url($input, PHP_URL_HOST);

if ( false!==stripos($host, 'reddit.com') ) {
  //itsReddit();
  echo 'reddit';
}
