And through this tutorial; you can download free source code of PHP + MySQL login system with session.
Login with session using PHP and MYSQL database
Use the below given steps to create login form with session in php and mysql source code:
- Step 1 – Create PHP Project
- Step 2 – Create Database Table And Connect App to DB
- Step 3 – Create Login Form In HTML
- Step 4 – Create User Profile File
Step 1 – Create PHP Project
In step 1, Navigate to your local web server directory. And inside this directory, create one directory. And you can name this folder anything.
Here, I will “demo” the name of this folder. Then open this folder in any text editor (i will use sublime text editor).
Step 2 – Create Database Table And Connect App to DB
In step 2, you need to create database and table. So run the following sql query to create database and table:
CREATE DATABASE my_db; CREATE TABLE users( id int(11) NOT NULL PRIMARY KEY AUTO_INCREMENT, name varchar(255) NOT NULL, email varchar(255) NOT NULL, contact varchar(255) NOT NULL, password varchar(255) NOT NULL ) ENGINE=InnoDB DEFAULT CHARSET=latin1;
Then create a php file that named mydbCon. Which is used to connect phpmyadmin mysql database to project (demo).
So, now create mydbCon file and add the below given code into your file:
<?php
$hName='localhost'; // host name
$uName='root'; // database user name
$password=''; // database password
$dbName = "my_db"; // database name
$dbCon = mysqli_connect($hName,$uName,$password,"$dbName");
if(!$dbCon){
die('Could not Connect MySql Server:' .mysql_error());
}
?>
Step 3 – Create Simple Login Form In HTML
In step 3, create a php file that named login.php. This file will display PHP login form and authenticate user from MySQL database. Now, you need to add the following login form code into login.php file:
<?php
session_start();
require_once "mydbCon.php";
if (isset($_SESSION['user_id']) != "") {
header("Location: user-profile.php");
}
if (isset($_POST['login'])) {
$email = mysqli_real_escape_string($conn, $_POST['email']);
$password = mysqli_real_escape_string($conn, $_POST['password']);
if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
$email_error = "Please Enter Valid Email ID";
}
if (strlen($password) < 6) {
$password_error = "Password must be minimum of 6 characters";
}
$result = mysqli_query($conn, "SELECT * FROM users WHERE email = '" . $email . "' and password = '" . md5($password) . "'");
if ($row = mysqli_fetch_array($result)) {
$_SESSION['user_id'] = $row['uid'];
$_SESSION['user_name'] = $row['name'];
$_SESSION['user_mobile'] = $row['mobile'];
$_SESSION['user_email'] = $row['email'];
header("Location: dashboard.php");
} else {
$error_message = "Incorrect Email or Password!!!";
}
}
?>

Step 4 – Create User Profile File
In step 4, create new file that named user-profile.php file. Because this is used to show loggedIn User information,
So, add the below code into your user-profile.php file:
<?php
session_start();
if(isset($_SESSION['user_id']) =="") {
header("Location: login.php");
}
?>
