note 100543 added to language.oop5.typehinting

I have made a little bench between three method of type hinting for native type (string, integer, ...). First method : by test type in function like : <?php function testTest($arg) { if (!is_string($arg)) { trigger_error('Argument $arg passed to test must be an instance of string, other given'); } return $arg; } ?> Second method : by object representing native type : <?php function testObject(StringObj $arg) { return $arg; } ?> Third method : by class TypeHint proposed by Daniel : <?php function testHint(string $arg) { return $arg; } ?> the results are here : bench for 100000 iterations, in seconds avg min max total test 5.3275489807129E-6 2.8610229492188E-6 0.0033020973205566 0.53275895118713 object 4.9089097976685E-6 3.814697265625E-6 0.0025870800018311 0.49089503288269 hint 3.2338891029358E-5 2.9802322387695E-5 0.0025920867919922 3.2338931560516 As you can see, the method by object is the best now you know... ---- Server IP: 69.147.83.197 Probable Submitter: 83.206.36.129 ---- Manual Page -- http://www.php.net/manual/en/language.oop5.typehinting.php Edit -- https://master.php.net/note/edit/100543 Del: integrated -- https://master.php.net/note/delete/100543/integrated Del: useless -- https://master.php.net/note/delete/100543/useless Del: bad code -- https://master.php.net/note/delete/100543/bad+code Del: spam -- https://master.php.net/note/delete/100543/spam Del: non-english -- https://master.php.net/note/delete/100543/non-english Del: in docs -- https://master.php.net/note/delete/100543/in+docs Del: other reasons-- https://master.php.net/note/delete/100543 Reject -- https://master.php.net/note/reject/100543 Search -- https://master.php.net/manage/user-notes.php
