Pincode registration

[seyz4all]

Hi everyone,

i have seen so many website that requires a pincode and serial no to signup, then when loging in, you would use ur pincode and ur own password.

 

i believe the pincode and serial nos are already in the database b4 the registration was made, cos one wld use d pincode and serial no to register.

 

Pls I have been searching for scripts like dis, but cant find it.

Or if anyone has a script like dat.

 

Guys please help me out.

<?php
function RandomString($m,$mx,$isspecial=null)
{
$min = $m;
$max = $mx;
$passwd = "";

$passwdstr = "abcdefghijklmnopqrstuvwxyz";
$passwdstr .= strtoupper($passwdstr);
$passwdstr .= "12345678901234567890"; 

for($i=0; $i<=strlen($passwdstr) - 1; $i++) {
    $passwdchars[$i]=$passwdstr[$i];
}

srand ((float)microtime()*1000000);
shuffle($passwdchars);

$length = rand($min,$max); 


for($i=0; $i<$length; $i++) {
$charnum = rand(0, count($passwdchars) - 1);
$passwd .= $passwdchars[$charnum];
}

return htmlentities($passwd);

}
?>

This function generates pin numbers.. what happens in real scenario is that , a pin is generated , and an entry is made into the table , i.e. a pin is assigned to the user id .
