A strange bug in php_PHP tutorial

$data = array('server' => false);

echo $data['server']["test"];

One might say NULL and NOTICE undefined index "test"

I thought so at first, but in fact it is not the case. NULL will be output, but NOTICE is not generated. This is really a cheating implementation
