session - Use cookie in a PHP login page -


i'm create form login php (and, obviously, mysql). php code: 

<?php $host = 'localhost'; $db_user = 'root'; $db_password = ''; $db_name = 'learningsql';  $username = stripslashes($_post['username']); $password = stripslashes($_post['password']);  if (strlen($username) < 1 || strlen($password) < 1){     echo "username or password incorrect"; } else {     $username = trim(filter_var($_post['username'], filter_sanitize_string));     $password = trim(filter_var($_post['password'], filter_sanitize_string));     $hash = hash("sha512",$username. $password);     $connection = mysqli_connect($host, $db_user, $db_password);     $db = mysqli_select_db($connection, $db_name);     $result = mysqli_query("select * utenti username = '$username' , password = '$hash'");     if(mysqli_num_rows($result)==0{         die("username or password incorrect");     } else{         $_session['loggedin']=1;         $user = mysqli_fetch_array($result);         header("location:loggato.php");      } } ?>

the .html page form contains php code session: 

<?php session_start(); if(isset($_session['loggedin']))     header('location:loggato.html'); ?>

but, have problem. use @ moment login's sessions, wanna use cookie. how? answers.

the php session stores cookie enable session. function session_start() start session (duhh) , session set cookie called phpsessid. check in browser dev tool.
