note 107481 added to language.operators.logical

Regarding [ctulek at gmail dot com 18-Oct-2010 02:07] not dangerous if you use the === operator, or understand PHP type juggling; adding to your example: <?php $a = 0; $b = 'G'; $c = false; // 3 lines added ... var_dump((int) 'G'); // => 0 var_dump((bool) 0); // => false var_dump((bool) 'G'); // => true echo ($a == $b) ? "true\n" : "false\n"; // 0 == 0 => true echo ($a == $c) ? "true\n" : "false\n"; // false == false => true echo ($c == $b) ? "true\n" : "false\n"; // false == true => false // 3 lines added ... echo ($a === $b) ? "true\n" : "false\n"; // => false echo ($a === $c) ? "true\n" : "false\n"; // => false echo ($c === $b) ? "true\n" : "false\n"; // => false ?> ---- Server IP: 69.147.83.197 Probable Submitter: 72.219.151.91 ---- Manual Page -- http://www.php.net/manual/en/language.operators.logical.php Edit -- https://master.php.net/note/edit/107481 Del: integrated -- https://master.php.net/note/delete/107481/integrated Del: useless -- https://master.php.net/note/delete/107481/useless Del: bad code -- https://master.php.net/note/delete/107481/bad+code Del: spam -- https://master.php.net/note/delete/107481/spam Del: non-english -- https://master.php.net/note/delete/107481/non-english Del: in docs -- https://master.php.net/note/delete/107481/in+docs Del: other reasons-- https://master.php.net/note/delete/107481 Reject -- https://master.php.net/note/reject/107481 Search -- https://master.php.net/manage/user-notes.php
