I don't know. Let's just say false resolves to "a". ${!$a=ReturnArray()}['a'] $a is now the array. The ! changes the returned array into the boolean false (like: if (!$handle = fopen('x', 'r')) { echo 'connection failed' }. ${false}['a'] I don't know what false resolves to, but we're using "a". $a['a'] ?> -- -Casey -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
