Session Data Loss in Chrome: Resolving the Mystery

Similar to the issue described in the referenced thread, PHP developers have encountered a peculiar behavior where session data is lost specifically in Google Chrome. While the session cookie is being sent and accepted, session data stored in $_SESSION is not retained.

Despite ensuring proper session initialization and handling, the issue persists in Chrome. Upon examination using network monitoring tools, it becomes evident that the session itself is not being dropped, but rather the specific variable $_SESSION['last_viewed_element'] is not being preserved. Other variables set in the session are also lost.

Unexpected Solution: Embracing Cookies

After extensive troubleshooting, the issue was resolved by switching from sessions to cookies. This implies that while Chrome may have limitations in handling session data, it operates seamlessly with cookies.

Potential Root Cause

While the exact cause of this behavior is still a mystery, a related observation emerged. In some cases, the problem was attributed to a 404 error caused by a missing favicon.ico in Chrome. This triggered an unnecessary PHP script execution, altering the session variables.

Conclusion

Developers facing session data loss in Chrome only may consider utilizing cookies as an alternative to sessions. Additionally, it is advisable to thoroughly investigate any potential 404 errors, as they can have unexpected consequences on session behavior and lead to data loss.
