As of 7.x, the way that objects are handled in pass-by-reference has changed:
function foo(&$bar)
{
// The function need not do anything
}
$test = null;
foo($test->var);
// $test is now an object with a ->var property, even though it hasn't been set anywhere
In 5.x, $test was left unset after the call to foo().
