note 108100 added to function.rand

Since many people (myself included) come to this page looking for a way to do a random string, I present a way that uses arrays and shuffle() instead of rand(). This also has the effect of not repeating any characters in the value set. $arr = str_split('ABCDEFGHIJKLMNOP'); // get all the characters into an array shuffle($arr); // randomize the array $arr = array_slice($arr, 0, 6); // get the first six (random) characters out $str = implode('', $arr); // smush them back into a string ---- Server IP: 69.147.83.197 Probable Submitter: 129.83.31.3 ---- Manual Page -- http://www.php.net/manual/en/function.rand.php Edit -- https://master.php.net/note/edit/108100 Del: integrated -- https://master.php.net/note/delete/108100/integrated Del: useless -- https://master.php.net/note/delete/108100/useless Del: bad code -- https://master.php.net/note/delete/108100/bad+code Del: spam -- https://master.php.net/note/delete/108100/spam Del: non-english -- https://master.php.net/note/delete/108100/non-english Del: in docs -- https://master.php.net/note/delete/108100/in+docs Del: other reasons-- https://master.php.net/note/delete/108100 Reject -- https://master.php.net/note/reject/108100 Search -- https://master.php.net/manage/user-notes.php
