A session is a mechanism to save data (in the form of variables) for usage on numerous pages. The information is not saved on the user's computer, unlike a cookie.

The different types of sessions that can be conducted include:

  • A one-on-one session with a counselor
  • A group session with other participants
  • A support group session
  • An online support group session (online)

Session data is stored in the database using a technique called serialization. Serialization is the process of converting a data structure into a stream of bytes that can be sent over a communications channel.

The following are some of the benefits of using serialization:

  • Serialized data can be transmitted from one computer to another without any loss or corruption
  • It also makes it possible for multiple computers to share and update the same database
  • It's also easier to read and write sequential data, which means that it's easier to perform certain tasks like sorting, filtering, and grouping

  • PHP is a programming language that is used for web development. It is one of the most popular languages in the world and has been around for over 25 years.
  • In this session, we will have an overview of PHP, its history, and some of the best practices that you should follow when you are developing a website using PHP.
  • This session will be helpful to those who are new to programming and want to learn more about how to use PHP on their website development project.

  • PHP sessions are used to store information on a given website. They are often used to store user data, such as names, addresses, and other details.
  • Sessions are also used for storing session-related information like user preferences and login statuses. Sessions can be stored in either in the server or in the browser.
  • Session cookies are stored on the server, which means that they need to be stored somewhere else, such as a database or file system. Session cookies are limited to a particular domain and cannot be accessed by other websites or servers that use PHP sessions.
