Then Sir how I can implement Forget Password Module for user???//

Plz help............

johny30238 · December 23, 2010

I assume you will have to create a script that will create a new password & before encryption it will send a email to the user with the new generated pass. Just a idea.... But if you read the thread, it does show how to implement a mysql encryption

but how i can generate new password to user.....???????????????/

I don't know script ........

Help...............

Well this is just one way of doing it. I excluded some chars from ASCII that could be confusing in a password.

<?php

$blacklist = "´`^',."; // Not wanted chars
$pass = "";
do
{
    $chr = chr(rand(33,122));
    $pass .= (stripos($blacklist, $chr) !== FALSE) ?: $chr;
} while(strlen($pass) < 10); // Make 10 characters long password

?>
