note 29565 added to function.mt-srand

Very good points above on seeds, thank you. If you would like to test a seed try using the code below. It will take between 5 and 20 seconds depending on your system and then will spit out the number of reused keys out of 100,000 attempts. ; for ($i=0; $i<100000; $i++) { ; mt_srand(hexdec(substr(md5(microtime()), -8)) & 0x7fffffff); ; $rand = mt_rand(); ; ; ($arr[$rand] == '1') ? $k++ : $arr[$rand] = '1'; ; } -- http://www.php.net/manual/en/function.mt-srand.php http://master.php.net/manage/user-notes.php?action=edit+29565 http://master.php.net/manage/user-notes.php?action=delete+29565 http://master.php.net/manage/user-notes.php?action=reject+29565
