note 86615 added to function.isset

Here's a simple function to test if the variable is set: function is($var) { if (!isset($var)) return false; if ($var!==false) return true; return false; } Now instead of very popular (but invalid in many situations): if (!$var) $var=5; you can write: if (!is($var)) $var=5; ---- Server IP: 82.177.164.100 Probable Submitter: 83.9.63.21 ---- Manual Page -- http://www.php.net/manual/en/function.isset.php Edit -- https://master.php.net/note/edit/86615 Del: integrated -- https://master.php.net/note/delete/86615/integrated Del: useless -- https://master.php.net/note/delete/86615/useless Del: bad code -- https://master.php.net/note/delete/86615/bad+code Del: spam -- https://master.php.net/note/delete/86615/spam Del: non-english -- https://master.php.net/note/delete/86615/non-english Del: in docs -- https://master.php.net/note/delete/86615/in+docs Del: other reasons-- https://master.php.net/note/delete/86615 Reject -- https://master.php.net/note/reject/86615 Search -- https://master.php.net/manage/user-notes.php
