Previously an offset like "foo" was silently cast to 0." That warning will suppressed by wrapping variable in isset() or empty(); http://3v4l.org/MEldp Test script: --------------- <?php $a = 'foo'; var_dump($a['bar']); // warning var_dump(empty($a['bar'])); // no warning var_dump(isset($a['bar'])); // no warning ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=65751&edit=1
