Ideas for Random Number Generation Function.

[pzed1]

Okay, I have form problem and am looking for suggestions on the proper way to code this tiny application.

I have included an image to make things clearer

*It's a 2 part form

1. Generate different random numbers that are between and ____

2. Use the Randomly generated set of numbers from (1) to generate a new series of numbers (with the conditions found in the image).

Thoughts? Suggestions? Pointers?

function return_number () { 

// set password length 
$pw_length = 18; 
// set ASCII range for random character generation 
$lower_ascii_bound = 48;          // "0" 
$upper_ascii_bound = 57;       // "9" 

    // Exclude special characters and some confusing alphanumerics 
    // o,O,0,I,1,l etc 
    $notuse = array (58,59,60,61,62,63,64,73,79,91,92,93,94,95,96,108,111); 

    while ($i < $pw_length) { 
            mt_srand ((double)microtime() * 1000000); 
            // random limits within ASCII table 
            $randnum = mt_rand ($lower_ascii_bound, $upper_ascii_bound); 
            if (!in_array ($randnum, $notuse)) { 
                    $password = $password . chr($randnum); 
                    $i++; 
            } 
    } 

return $password; 
$new_password = return_number(); 
}
$new_password = return_number(); 
echo "$new_password";

echo return_number();
