note 30583 added to function.empty

I found empty() useful at the beginning of user defined functions, in which I check to make sure any necessary variables are present before going into any logic. This makes it easier for me to control some errors. function foo_bar($var1,$var2){ ...if (empty($var1) or empty($var2)){ ......echo "You must pass var1 and var2 to this function"; ......exit(); ...{ ...<other logic> } Seems to do the job :-) -- http://www.php.net/manual/en/function.empty.php http://master.php.net/manage/user-notes.php?action=edit+30583 http://master.php.net/manage/user-notes.php?action=delete+30583 http://master.php.net/manage/user-notes.php?action=reject+30583
