All About PHP sessions

Here you can find information about PHP Sessions. Enjoy!

What are They?

A session is a way to store information (in variables) to be used across multiple pages. Unlike a cookie, the information is not stored on the user’s computer.

Why/when it is appropriate to use

It allows the website to remember a user and their information across multiple web pages. Web servers do not remember who you are by default. PHP sessions change that by using session variables that store user information to be used across several pages. By default, session variables last until the user closes the browser.

Security considerations

Sessions hold individual data for each user that can cause considerable performance and security issues if mishandled or misused. Improper session management can lead to a wide variety of attacks, including session hijacking and session fixation.
