note 18770 added to function.empty

if you are wanting to know if a string is set and is not null, you would be best to use strlen() instead of empty() to avoid the typemorph nonsense (in particular, "0" == false) while still preserving efficiency and logical presentation, i.e.: if (strlen($string)) { echo "string was set to ".$string; } else { echo "string was not set"; } -- http://www.php.net/manual/en/function.empty.php http://master.php.net/manage/user-notes.php?action=edit+18770 http://master.php.net/manage/user-notes.php?action=delete+18770 http://master.php.net/manage/user-notes.php?action=reject+18770
