note 98522 added to function.empty

For everyone who is offering functions to replace empty() please remember that php will report an "Undefined variable" warning when you try to call a function with an unset variable. The only safe way to do it is to use <?php if(isset($var)){call_function_to_replace_empty($var);} ?> ---- Server IP: 89.185.144.38 Probable Submitter: 86.43.117.247 ---- Manual Page -- http://www.php.net/manual/en/function.empty.php Edit -- https://master.php.net/note/edit/98522 Del: integrated -- https://master.php.net/note/delete/98522/integrated Del: useless -- https://master.php.net/note/delete/98522/useless Del: bad code -- https://master.php.net/note/delete/98522/bad+code Del: spam -- https://master.php.net/note/delete/98522/spam Del: non-english -- https://master.php.net/note/delete/98522/non-english Del: in docs -- https://master.php.net/note/delete/98522/in+docs Del: other reasons-- https://master.php.net/note/delete/98522 Reject -- https://master.php.net/note/reject/98522 Search -- https://master.php.net/manage/user-notes.php
