Checking for a specific user

I have the following code which makes sure that the user is logged in. But I want to change to code to check for a specific user id. Can anyone help me with this?

function protect_page() {
    if (logged_in() === false) {
        header('Location: protected.php');
        exit();
    }
}

You can modify your function logged_in and pass the specific user id to the function:

function logged_in($id) {
    //this function checks if the user is logged in and has a specific id
    return (isset($_SESSION['user_id']) && $_SESSION['user_id'] === $id) ? true : false;
}

You have to change your protect_page function to fit the new logged_in function:

function protect_page() {
    if (logged_in(7) === false){
        header('Location: protected.php');
        exit();
    }
}

You could update your login function with an extra optional variable. If you don't specify the $user_id variable it will take the value 0, which will only check if the user is logged in. If you do specify a certain $user_id then the function will return true if the user is logged in and the $user_id matches the id stored in the session.

function logged_in($user_id = 0) 
{
    return (isset($_SESSION['user_id']) && (($user_id == 0) || ($_SESSION['user_id'] == $user_id))) ? true : false;  //this function checks if the user is logged in and matches the given user identifier.
}
