Question

I am really confused with this one. Here’s my code

class inner
{
    var $val = 0;   
}

class outer
{
    var $obj=null;

    function outer()
    {
        $this->obj = new inner;
    } 

    function get_obj()
    {
        return $this->obj;
    }
}


$app = new outer;

$obj = &$app->get_obj(); //get object by reference (& is not necessary in PHP5)
$obj->val = 1; //change something
echo $app->obj->val; //check whether it affected the original object source
//here it should display 1

When I am testing this on my local server, which is PHP 5.2.10-2ubuntu6.4, everything works fine and it displays 1. When I am testing this on my customer’s PHP Version 5.2.9 server, it displays 0. Is there some known PHP bug or may be some php.ini setting that could affect this behavior?

Answer 1

If not works, try replace this

function get_obj()

By this

function &get_obj()
