Yeah i know, every good programmer loves ‘goto’ statement ;) I did not used it jet, but it works well i think, and was just written by me for some pal.

Code below uses the WHILE loop with a SWITCH statement to generate jumps between needed CASE: conditions. But You have to watch for the $condition or set emergency counter ($ctr) to avoid endless loop.

$code = 304;    // start with some example code
$fork_question = false;  // some IF to fork
$condition = false;  // break if $condition is set or just secure the loop

$ctr = 0;  // exit help counter or needed loops count (5 is set for example)

while( !$condition || $ctr == 5 ) {
    switch ( $code ) {
    case 1:
        echo "in case 1<br />";
        break;
    case 304:
       {
       echo "in case 304<br />"; 
       if ($fork_question)
         {
         echo "never here<br />";
         }
         else
            {
            echo "Try to jump to 'Label' 404 code<br />"; 
            $code = 404; // set the new code - our LABEL jump
            break 1;
            }
      }
    case 390:
       echo "in case 390<br />";
       break;  
    case 404:
       echo "in case 404<br />";
       $condition = true;     // !
       break;    

    default:
      {
      echo "DEFAULT<br />"; 
      break;
      }
  }

$ctr++;
echo "Loop: ".$ctr."<br />";
}

echo "end<br />";
exit;

Please use it free as always.
