php - __clone method is not making copy of class object -


i want use __clone() making copy of class object , after want print copy object. here code:

<?php class test {      public static $counter = 0;     public $id;     public $other;       public function __construct(){         $this->id = self::$counter++;      }      public function __clone()     {        $this->other = $that->other;        $this->id = self::$counter++;     } }  $obj = new test(); $copy = clone $obj; print_r($copy); ?>

instead of 

$copy = $obj->__clone();

you should use

$copy = clone $obj;

the __clone() method called when call clone
