Note Submitter: nggit at anggit dot com ---- Sometimes I do not want to use isset() or array_key_exists() to check the index exists or not, but rather choose to define in advance. Union array operator is pretty handy for me: <?php $_GET += array('foo' => null, 'bar' => null); // define echo $_GET['foo']; echo $_GET['baz']; // Notice: Undefined index: baz in... ?>
