Note Submitter: glitch dot mr at gmail dot com ---- 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.
