From http://php.net/manual/en/control-structures.switch.php

"The case expression may be any expression that evaluates to a simple type, that is, integer or floating-point numbers and strings. Arrays or objects cannot be used here unless they are dereferenced to a simple type."

However, when I pass an object, it seems to work fine.

Test script:
---------------
 class X { public $j;  }
 class Y { public $j;  }
        
 $x = new X(); 

 switch ($x) {
            case new Y():
                return "Matched a Y";
                break;
            case new X():
                echo "Matched an X";
                break;
            default:
                echo "No match";
                break;
            //outputs "Matched an X"
        }
