I thought Yeah pointer likly behavior... but i watched serilized objects and what i did see? referenced Objects are outputed like the object self.



Here is a simple code, it shows that the references are sweet but in some case (storing objects to $_SESSION or Database) unuseable:



<?php

class foo{

    private static $id_c = 0;

    public $ref;

    public $id;

    public function foo(){

        $this->id=self::$id_c++;

    }    

}

$a = new foo();

$b = new foo();

$a->ref = &$b;



print_r($a);

echo "<br/>";

print_r($b);

echo "<br/><br/>";



$a->ref->id
