Answer 1

Try implementing "magic" method __toString() in you object class:

http://php.net/manual/en/language.oop5.magic.php#object.tostring

and inside it generate name of you object. So, add it like:

public function __toString()
{
    return $this->foo;
}

Your function just has to return a string. Use variables you have in your object to generate that string.
