generate password

[router]

Hello!
How can i generate a new password?
Actually, i use this code:

function CREATE_PSW($size = 8)
{ # this function generates a character ID
srand((double)microtime()*1000000);

$pool = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
$pool .= "abcdefghijklmnopqrstuvwxyz";
$pool .= "0123456789";

for($index = 0; $index < $size; $index++)
{ $id .= substr($pool,(rand(1,100000)%(strlen($pool))),1); 
   $resultado = rand(1,1000000);
}
return($id);

}
In windows and php 4.0 it works, but in linux and php 4.2 it doesn't do it. Srand always generates the same, 1 or 2.
What's wrong? what can i do?
Thanks!

From php.net:

Note: Since PHP 4.2.0 it's no longer necessary to seed the random number generator before using it.

So you actually dont have to use srand().

This is what I use to generate random passwd:

<?php
function passwd($numofletters)
{
// here you put the letters and numbers what you want to use in passwd

$letters = "ABCDEFGHIJKLMOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz1234567890";
$len=strlen($letters);

for ($i=0; $i < $numofletters; $i++)
{
    $_rand=rand(0,$len);
    $password.=$letters{$_rand};
}
return($password);
}
?>

Thank you for your help, but it doesn't work!
I try it and only generate '0'.
I put "echo $_rand" and it always put '0'.
It drives me crazyyyyyyyyyyyyyyyyy!!!!
Any idea? is there any bug or somethig like that?
Thanks!

Hmm.. Thats really strange. That script works for my homeserver(Windows,apache) and on FreeBSD,Apache.

That problem would drive me crazy too 🙂

I have used this function succesfully

function mkpasswd($nochars=8)
{
mt_srand ((double) microtime() * 1000000);
$letters="ABCDEFGHJKLMPQRSTUVWXYZabcdefghjkmnpqrstuvwxyz23456789";
$len=strlen($letters);

for ($loop=0; $loop<$nochars; $loop++) 
{
    $randno=mt_rand(0,$len);
    $password.=substr($letters, $randno, 1);
}
return($password);

}

It uses mt_rand instead of rand. I dont know if thats significant or not.

Mark.
