Hi Everybody... 🙂

$random_password = makeRandomPassword();

$db_password = md5($random_password);

$sql = mysql_query("UPDATE users SET password='$db_password' WHERE email_address='$email_address'");

$subject = "Your Password at MyWebsite!";
$message = "Hi, we have reset your password.

New Password: $random_password
