note 108768 added to function.isset

This is very simple implementation of issetor() for PHP. It works like ?? in C#, // in Perl (it can access undefined hash keys without it nevertheless) or ? in CoffeeScript (also can access undefined hash keys too). You shouldn't use directly $_GET['something'] (it can generate E_NOTICEs in case somebody would try hacking your site), but isset($_GET['something']) ? $_GET['something'] : '' is long for many people (for so common operation). This alternative makes using superglobals easier. <?php function issetor(&$variable, $or = NULL) { return $variable === NULL ? $or : $variable; } ?> Now you can do: <?php echo issetor($_GET['a']); // $_GET['a'] or NULL echo issetor($_GET['b'], '42'); // $_GET['b'] or 42 echo issetor($_GET['c']['d']); // $_GET['c']['d'] or NULL ?> This code doesn't generate notices in case variable doesn't exist. ---- Server IP: 69.147.83.197 Probable Submitter: 178.36.22.238 ---- Manual Page -- http://www.php.net/manual/en/function.isset.php Edit -- https://master.php.net/note/edit/108768 Del: integrated -- https://master.php.net/note/delete/108768/integrated Del: useless -- https://master.php.net/note/delete/108768/useless Del: bad code -- https://master.php.net/note/delete/108768/bad+code Del: spam -- https://master.php.net/note/delete/108768/spam Del: non-english -- https://master.php.net/note/delete/108768/non-english Del: in docs -- https://master.php.net/note/delete/108768/in+docs Del: other reasons-- https://master.php.net/note/delete/108768 Reject -- https://master.php.net/note/reject/108768 Search -- https://master.php.net/manage/user-notes.php
