Here is a function I found a while back that I use for Random Password creation
##############################################
function str_makerand () {
$minlength = 5;
$maxlength = 10;
$useupper = 1;
$usespecial = 0;
$usenumbers = 1;

Description: string str_makerand(int $minlength, int $maxlength, bool
$useupper, bool $usespecial, bool $usenumbers)
returns a randomly generated string of length between $minlength and
$maxlength inclusively.
Notes:
- If $useupper is true uppercase characters will be used; if false they
will be excluded.
- If $usespecial is true special characters will be used; if false they
will be excluded.
- If $usenumbers is true numerical characters will be used; if false
they will be excluded.
- If $minlength is equal to $maxlength a string of length $maxlength
will be returned.
- Not all special characters are included since they could cause parse
errors with queries.

$charset = "abcdefghijklmnopqrstuvwxyz";
if ($useupper) $charset .= "ABCDEFGHIJKLMNPQRSTUVWXYZ";
if ($usenumbers) $charset .= "123456789";
if ($usespecial) $charset .= "[EMAIL PROTECTED]()_+-={}|]["; // Note:
using all special characters this reads: "[EMAIL
PROTECTED]&*()_+`-={}|\\]?[\":;'><,./";
if ($minlength > $maxlength) $length = mt_rand ($maxlength, $minlength);
else $length = mt_rand ($minlength, $maxlength);
for ($i=0; $i<$length; $i++) $key .=
$charset[(mt_rand(0,(strlen($charset)-1)))];
return $key;
}
