Re: Netscape rand() not random

you need to seed the rand with srand() before the rand() command... cheers, Rom ----- Original Message ----- From: Joel Dossey <smokin_joel@yahoo.com> To: <php-general@lists.php.net> Sent: Wednesday, January 17, 2001 1:39 PM Subject: [PHP] Netscape rand() not random Hello, I have been toying with php for a short while and have problems getting the following code to correctly execute on Netscape: <?php header ("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); header("Last-Modified: ".gmdate("D, d M Y H:i:s",getlastmod())." GMT"); header ("Cache-Control: no-cache, must-revalidate"); header ("Pragma: no-cache"); for($i=0; $i<40; $i++) { $rand= rand(1, 40); print "$rand<BR>"; } ?> I included the headers because I thought this would prevent caching, but even still, everytime I reload and shift-reload Netscape (browser cache is set to zero) I receive the same output from first access, which really ruins any true random activity. Any ideas? thanks much, Joel Dossey __________________________________________________ Do You Yahoo!? Get email at your own domain with Yahoo!
