note 129127 added to function.srand

Keep in mind that now srand is an alias for mt_srand, but they behaved differently before. This means you should not follow the documentation of srand, but the one of mt_srand, when using srand. To reset the seed to a random value, mt_srand(0) (or srand(0)) doesn't work. It sets the seed to 0. To reset the seed to a random value you must use mt_srand() (or srand()). <?php $arr = [0, 1, 2, 3, 4]; srand(1); // or mt_srand(1) as they are now aliases $keys = array_rand($arr, 2); // not random as expected srand(0); // or mt_srand(0) as they are now aliases $keys = array_rand($arr, 2); // not random either! srand(); // or mt_srand() as they are now aliases $keys = array_rand($arr, 2); // random again ?> ---- Server IP: 45.112.84.4 Probable Submitter: 45.91.157.134 (proxied: 2a01:cb04:580:1500:af59:b3c2:2e85:b329) ---- Manual Page -- https://php.net/manual/en/function.srand.php Edit -- https://main.php.net/note/edit/129127 Del: integrated -- https://main.php.net/note/delete/129127/integrated Del: useless -- https://main.php.net/note/delete/129127/useless Del: bad code -- https://main.php.net/note/delete/129127/bad+code Del: spam -- https://main.php.net/note/delete/129127/spam Del: non-english -- https://main.php.net/note/delete/129127/non-english Del: in docs -- https://main.php.net/note/delete/129127/in+docs Del: other reasons-- https://main.php.net/note/delete/129127 Reject -- https://main.php.net/note/reject/129127 Search -- https://main.php.net/manage/user-notes.php
