Random Password PHP code help req.. only gettinh 3 letters?

[techcs]

Hi,

Wondering if anyine can help with the membership PHP script I lifted
from a tutorial. I'm new to PHP and have this system up and running but
my password only come out at three letters and sometime have a space in
them?? Anyway this is the code:

function makeRandomPassw ord($len = 8,$upper = 1,$number = 1) {
$salt = "abcdefghijklmn opqrstuvwxyz";
$uppercase = "ABCDEFGHIJKLMN OPQRSTUVWXYZ";
$numbers = "1234567890 ";
if ($upper) $salt .= $uppercase;
if ($number) $salt .= $numbers;

srand((double)m icrotime()*1000 000);
$i = 0;
while ($i <= $len) {
$num = rand() % strlen($salt);
$tmp = substr($salt, $num, 1);
$pass = $num . $tmp;
$i++;
};
return $pass;
};

$random_passwor d = makeRandomPassw ord();

$db_password = md5($random_pas sword);

Any ideas.. I need maybe 5 letters with no spaces...

Thanks
Col

I'd replace this part...

$i = 0;
while ($i <= $len) {
$num = rand() % strlen($salt);
$tmp = substr($salt, $num, 1);
$pass = $num . $tmp;
$i++;
};

.... with this code:

$pass='';
$max=strlen($sa lt)-1;
for($i=0; $i<$len); $i++){
$pass.=$salt{mt _rand(0, $max)};
}

Hi, thanks for that but I get a parse error with that code, maybe I
have to change some of the other bit to match, will have another
look...

Cheers

I didn't test the code. Just remove the unexpected ')'.
