You try to access a variable without it first being defined. If you define it first, you won't get an error.

<?php

$x = new stdClass();
$y = $x->z;   // gererates Notice in error_log


$x = new stdClass();
$x->z = 'assigned';    // now it is assigned
$y = $x->z;  // no error

// or you could make your own class
class Whatever
{
    public $z;
}

$x = new Whatever();
$y = $x->z;  // it's there whether a value has been assigned or not
