note 28708 deleted from function.empty by aidan

Note Submitter: Dan Hansen ---- As far as I can tell, the only useful purpose of empty() is to do this: if (!$var) { do_something(); } without getting a NOTICE error. This code will return no errors with error_reporting(E_ALL): if (empty($var)) { do_something(); } The isset() function is very helpful to find if a form field was submitted as blank. I could give an example but I think somebody alreay did in here. My point is that isset() and empty() are redundant but they do allow you to program in error_reporting(E_ALL) without warnings or notices, which usually means more secure scripts...
