PHP's assignment by reference is not working as expected

Question

Why the following

class AClass
{
    public function __construct ()
    {
        $this->prop = \"Hello\";
    }
    public function &get ()
    {
                


        

Answer 1

Your function func() needs to return a value and then it needs to assign to a variable what func() returned. See modified code below:

function func (&$ref) {
    $ref = &$ref->get();
    return $ref;
}

$value = new AClass();
$new_value = func($value);
var_dump( $new_value );
