is pretty non-intuitive. If the same value was 1 or true you get a warning and it halts. Since we can't break BC completely (yet) lets bump this from E_STRICT. Also added a new section to UPGRADING for engine changes. <?php $x = ''; // $x = null; // $x = false; $x->baz = 1; var_dump($x); $y = 1; $y->baz = 1; var_dump($y);
