Question

echo 'test';

class createdclass {
    public $name;
}

class testc {
    function &testm(){
        $myvar =& new createdclass();
        return $myvar;
    }
}

$testo = new testc();

$a =& $testo->testm();
$a->name = 'Douglas';

$b =& $testo->testm();
$b->name = 'Scott';

echo $a->name;
echo $b->name;

myvar is a reference to an object
a and b are references to the same object
I changed a, then I changed b, but a wasn’t changed by b
Why?

Answer 1

In your code each call to testm() creates a new instance of createdclass. So $a and $b aren’t the same object.
