How to check if a user is logged-in in php?

Question

I\'m pretty new to php and I am trying to figure out how to use sessions to check and see if a user is logged into a website so that they would have authorization to access

Answer 1

you may do a session and place it:

//start session
session_start(); 

//check do the person logged in
if($_SESSION['username']==NULL){
    //haven't log in
    echo "You haven't log in";
}else{
    //Logged in
    echo "Successfully log in!";
}

note:you must make a form which contain $_SESSION['username'] = $login_input_username;
