I've been working on a PHP project recently, and I'm currently facing an issue with the GET variable. I hope you can help me figure out what's going wrong.
So, to give you some context, my project involves retrieving data from a MySQL database and displaying it on a webpage. I'm using the GET method to pass a variable through the URL, which works fine most of the time. However, I've noticed that in some cases, the value I retrieve from the GET variable doesn't match what I'm expecting.
Let me explain with an example. Suppose I have a page called "profile.php" where I display a user's profile based on their ID. When I click on a user's profile link, let's say user ID 123, the URL becomes something like "profile.php?id=123". In my script, I use $_GET['id'] to retrieve the ID and fetch the corresponding data from the database.
Here's where the issue arises. Sometimes, when I click on the profile link for user ID 123, the $_GET['id'] variable returns a completely different value, like 456. This inconsistency is puzzling to me, as I expect it to always match the user ID in the URL.
I've tried debugging by printing out the value of $_GET['id'] before fetching the data, and it indeed shows the unexpected value. I've also double-checked that the profile links I click on have the correct user IDs in the URL.
Has anyone encountered a similar problem before? What could be causing this mismatch between the user ID in the URL and the value retrieved from the GET variable? Is there something I might be overlooking or any potential pitfalls I should be aware of?
Any insights or suggestions would be greatly appreciated. Thank you in advance for your help!
