if you want to exit function just do return;. But I’d just add some conditional blocks backed with if(). And to check if $matches array is empty do count(). So it could all look like this:

function myfn () {

   // where i get some data here and add result to an array
   $matches = array();
   preg_match_all('????????????', $searched, $matches);

   if( count($matches) > 0 ) {
     // there's something

     print_r($matches[1]);

   } else {

     // empty
     // send an email to [e-mail]

   }
}
