I'm currently working on a PHP project where I'm using sessions to store some user data. However, I'm facing an issue where I'm able to successfully set the session variable, but I'm unable to retrieve its values.
Here's the code snippet I'm working with:
// Setting the session variable
$_SESSION['username'] = 'JohnDoe';
// Trying to retrieve the value
$username = $_SESSION['username'];
The problem is that when I try to echo the value of `$username`, nothing is displayed on the screen. It seems like the session variable is not being stored or retrieved properly.
I have made sure to start the session using `session_start()` at the beginning of my code, so I don't think that's the issue. I have also checked my PHP configuration to ensure that sessions are enabled.
I would really appreciate any insight or suggestions on why I might be experiencing this problem. If there's any additional information needed, please let me know.
Thank you in advance for your help!
