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

You should remove the ampersand in your func function. Then it will return you the string.

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