In a login script, remember me feature is used to preserve the login name and password entered by the user. And it can be populated in the login form at the time of login. It minimizes the user effort by preventing to enter login details for each time.
Now we are going to see an example for login script with remember me feature. In this example, we are using PHP cookies for preserving user login and password.
PHP Login Form
This code shows login form with the PHP code to pre-populate user login and password. This form has a remember me check box. If it is set then the login details entered by the user will be preserved for future login attempts.

PHP Cookie to Remember Login
This PHP code validates the login details entered by the user while submitting the form. And it checks whether the remember me is checked. If so, it stores the user login and password in PHP $_COOKIE array. If these array variables are not empty then it will be populated in the login form fields.
