rand(min, max) always returns min

Howdy, I've seen this topic posted once before, but without ever reaching a conclusion. The earlier posting is at http://marc.theaimsgroup.com/?l=php-general&m=105414659615227&w=3 The problem: rand(min, max) always returns min on some systems. rand(), mt_rand, and mt_rand(min, max) all work fine. I've seen this fail on the following systems: 4.3.4/apache2/solaris 8 sparc 4.3.4/apache2/solaris 9 sparc 5.0.0b2/apache2/solaris 9 sparc But it works on 4.3.0/apache2/win2k 4.3.4/apache2/solaris 8 sparc All of the systems where it fails have /dev/*random on them. All of the systems where it works do not have /dev/*random on them. Code to test: <?PHP echo "version " . phpversion() . "<P>"; echo "rand(): " . rand() . "<P>"; // works echo "rand(1,100): " . rand(1,100) . "<P>"; // fails; always returns 1 echo "mt_rand(): " . mt_rand() . "<P>"; // works echo "mt_rand(1,100): " . mt_rand(1,100) . "<P>"; // works ?> Any insight or pointers as to why this might be failing will be appreciated. Thanks, jeff
