PHP Coding styles return; in switch/case

we're trying to implement new coding style guidelines for our team, the php codesniffer is printing an warning on switch case statements when no "break" is found like:

switch ($foo) {   
    case 1:
      return 1;   
    case 2:
      return 2;   
   default:
       return 3; 
}

is there any good reason to use :

   switch ($foo) {
       case 1:
         return 1;
         break;
   }

?? the break is never reached ?
