note 110540 added to language.operators.logical

In my opinion, PHP needs a more specific operator instead of "!" sign for readability of code for some situations. So, wich is more readable? <?php // id could be $id = 0; $id = ""; $id = null; $id = false; // not sign if (!$id) die("No id provided!"); // my not idea if (not $id) die("No id provided!"); // I don't mean this if ($id !== 0) ... if ($id not == 0) ... // but maybe this, ahh forget it if ($id not 0) ... // I use this for it but I think it's not suitable than a structure keyword function not($value) { return !$value; } if (not($id)) die("No id provided!"); if (not $id) die("No id provided!"); ?> ---- Server IP: 69.147.83.199 Probable Submitter: 78.173.125.108 ---- Manual Page -- http://www.php.net/manual/en/language.operators.logical.php Edit -- https://master.php.net/note/edit/110540 Del: integrated -- https://master.php.net/note/delete/110540/integrated Del: useless -- https://master.php.net/note/delete/110540/useless Del: bad code -- https://master.php.net/note/delete/110540/bad+code Del: spam -- https://master.php.net/note/delete/110540/spam Del: non-english -- https://master.php.net/note/delete/110540/non-english Del: in docs -- https://master.php.net/note/delete/110540/in+docs Del: other reasons-- https://master.php.net/note/delete/110540 Reject -- https://master.php.net/note/reject/110540 Search -- https://master.php.net/manage/user-notes.php
