note 71803 added to function.isset

"empty() is the opposite of (boolean) var, except that no warning is generated when the variable is not set." So essentially <?php if (isset($var) && $var) ?> is the same as <?php if (!empty($var)) ?> doesn't it? :) !empty() mimics the chk() function posted before. ---- Server IP: 194.246.101.61 Probable Submitter: 82.238.35.175 ---- Manual Page -- http://www.php.net/manual/en/function.isset.php Edit -- https://master.php.net/note/edit/71803 Del: integrated -- https://master.php.net/note/delete/71803/integrated Del: useless -- https://master.php.net/note/delete/71803/useless Del: bad code -- https://master.php.net/note/delete/71803/bad+code Del: spam -- https://master.php.net/note/delete/71803/spam Del: non-english -- https://master.php.net/note/delete/71803/non-english Del: in docs -- https://master.php.net/note/delete/71803/in+docs Del: other reasons-- https://master.php.net/note/delete/71803 Reject -- https://master.php.net/note/reject/71803 Search -- https://master.php.net/manage/user-notes.php
