Hi, I am looking at some codes. Some authors use $foo and isset($foo) interchangeably. Just to want to make sure that the statement,
if ($foo) { ... } is different from if (isset($foo)) { ... } Right? if ($foo) means variable exists and can be null. Whereas, isset($foo) means that the value in $foo cannot be null? Regards, Norman -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
