Ensure object comparison property order remains consistent

<?php

// PHP4-5.3 object semantics had child properties added to an
|
|
// object HashTable first, then parent, then grandparent, etc...
|
|
// As of PHP 5.4 we use a packed C array to hold properties
|
|
// which may or may not share the same ordering.
|
|
// In the code snippet below, the print_r() has the side-effect
|
|
// of materializing the properties shadow HashTable which
|
|
// if used for comparison, results in the behavior consistent
|
|
// with pre PHP-5.4.
|
|
// This test ensures that the first comparison yields the same
|
|
// result without shadow table materialization.
