Course Overview Hi, everyone. My name is Annapurna Agrawal, and welcome to my course, Cookies and Sessions in PHP. Cookies and sessions are an integral part of web applications. They are helpful in maintaining the state of an application and remembering the user while he uses our application. But the issue arises when the developers fail to understand the difference between them. In this course, we are going to see how different they are and how to work with both of them together to use them to the fullest. Some of the major topics that we will cover include how cookies came to picture. We will then see what are sessions and how they overcome the shortcomings of cookies, differentiating between cookies and sessions, and then, finally, we will learn about session security. By the end of this course, you will know what exactly cookies and sessions are and how using it efficiently can enhance user experience of our application. Before beginning the course, you should be familiar with the basics of PHP, and you should have a basic understanding of working with databases in PHP. I hope you will join me on this course to learn about these web elements with the Cookies and Sessions in PHP course only at Pluralsight.
