1.2.537. Identical Case In Switch

In a switch() or match() statement, when there are identical cases, it means that multiple case labels that have the same code block.

This can happen by mistake or design. They may be merged together.

<?php

switch($a) {
     case 1:
             $b = 2;
             break;

     case 2:
             $b = 12;
             break;

     // Identical to case 1
     case 3:
             $b = 2;
             break;
}

?>
