note 29712 added to function.empty

I do not use empty() nor isset() to check form input. When I want to know if some field has been filled in, I simply check if $field!=''. My reasons are: -empty() fails if the field has 0 (the zero value), which may be a value I need. -isset() always returns true for a POST var, even if the form field was empty. So instead of... if (!empty($field)) {...} // bad ...or... if (isset($field)) {...} // bad ...I use if ($field != '') {...} // good! As other comments here, I also believe empty() would be more use useful if it returned true for 0. -- http://www.php.net/manual/en/function.empty.php http://master.php.net/manage/user-notes.php?action=edit+29712 http://master.php.net/manage/user-notes.php?action=delete+29712 http://master.php.net/manage/user-notes.php?action=reject+29712
