Hi everyone,
I have a question regarding assigning a session variable in PHP. I want to set a variable to 0 only once, and then keep its value unchanged throughout the session.
Let me give you some context. I'm building a web application where users can track their progress. I have a session variable called "totalPoints" that keeps track of the user's accumulated points. Initially, when a user starts using the application, I want to set the "totalPoints" variable to 0. However, I want to make sure that this value remains unchanged for the entire session, even if the user refreshes the page or navigates to different sections of the application.
Could someone please guide me on how to achieve this in PHP? I've tried various approaches, but I'm unsure which one is the most efficient and reliable option.
I appreciate any help or suggestions you can provide. Thank you in advance!

Hey,
I faced a similar situation where I needed to assign a session variable to 0 only once in my PHP project. I found a simple and effective way to achieve this using the `$_SESSION` superglobal.
To ensure that the variable is assigned only once, you can check if it is not already set by using the `isset()` function. If it is not set, you can safely assign it the value of 0. Here's the code snippet that worked for me:
By using this approach, the session variable `totalPoints` will be initialized to 0 only if it is not already set. Once it is set, it will retain its value throughout the session even when the user navigates to different sections or refreshes the page.
Give it a try and let me know if you need further assistance. Good luck with your project!
