OK, to summarize what people have been saying so far: 1. DO NOT seed the RNG more than once if you can help it! 2. You HAVE TO seed the RNG yourself if you are using PHP < 4.2.0. 3. Using a prime multiplier to microtime() probably does very little. Use the Mersenne Twister instead. 4. You can use the Mersenne Twister PRNG with the mt_rand and mt_srand functions. This is faster and is more random. ---- Manual Page -- http://www.php.net/manual/en/function.srand.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+53577 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+53577&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+53577&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+53577&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+53577&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+53577&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+53577&report=yes Search -- http://master.php.net/manage/user-notes.php
