How to Create Login Page in PHP and MySQL with Session In my previous tutorial called "How to Create Secure Login Page in PHP/MySQL", I explain on the three ways on how create a login page using PHP/MySQL. This time, I will add more functionality on this tutorial. We will add session so that we will know if the visitor has logged in on our site or not. In PHP, there is a variable called $_SESSION. Session allow you to store information and used it in any pages that you like.

Validating a form using a JavaScript gives convenience to your visitors by avoiding page reload and other features that we discuss on our previous tutorial called Validate Login Page Using JavaScript. But validating a form using JavaScript alone is not safe. One reason is if the JavaScript is not enabled in the web browser.

This is a continuation of the topic that I have discuss yesterday on How to Create Secure Login Page in PHP/MySQL.

In our previous tutorial we discuss on how to create a secure registration page using three different approaches.

In our last two articles, we discuss on how to create a registration page using mysql and mysqli extension and how to secure it using mysql_real_escape_string or mysqli_real_escape_string.

This time we will modify our code to use PDO instead of mysql or mysqli extension.

mysqli extension works differently compared to mysql extension. The 'i' stands for improved. Which means that it has some features that cannot be found in mysql extension. There are two approach in using mysqli extension. They are Object Oriented style and Procedural style. If you are migrating your old PHP file to mysqli extension, I prefer you use the procedural style. It's very easy to convert it to mysqli this way. Looking at the example in our previous tutorial.

By secured we mean that we need to sanitize the data that is passed to our script in order to secure the registration of new account or user. There are three different types of connectivity in MySQL. They are: mysql = old MySQL function mysqli = improved MySQL function pdo = using prepared statement Mysql_connect is currently not supported in PHP version 5.5.0.
