If you want to generate a random password, use this code:
srand((double) microtime() * 1000000);
$pwd="";
while (strlen($pwd)<8) {
$r=rand(1, 3);
if ($r==1) {
$rcode=rand(48, 57);
}
if ($r==2) {
$rcode=rand(65, 90);
}
if ($r==3) {
$rcode=rand(97, 122);
}
$pwd.=chr($rcode);
}
echo $pwd;
but make shure to call srand() only _once_.
