[PHP] Which is better coding style...

[Boget, Chris]

Which is better?

function blah() {
  switch( $bob ) {
    case 1:
       return "this";

    case 2:
      return "that";

    default:
      return "other";

  }
}

function blah() {
  $retval = "";

  switch( $bob ) {
    case 1:
       $retval = "this";
       break;

    case 2:
      $retval = "that";
       break;

    default:
      $retval = "other";
       break;

  }
  
  return $retval;

}


In other words, is it good practice to exit out of a block (any
block... not just switch; if, for, while) prematurely as demon-
strated in the first example?  Or should you do it as demon-
strated in the second example?
