Why Are My PHP Sessions Lost After Redirection?

PHP Session Persistence After Redirection

A common issue in PHP web development is the loss of session data after a page redirect. To mitigate this problem, there are several troubleshooting steps you can take:

Basic Troubleshooting:

• Verify that session_start(); is called before any session data is accessed.
• Terminate the current script using exit(); after the redirect.
• Ensure that cookies are enabled in the browser.
• Check that the session data is not being explicitly cleared or overwritten.
• Confirm that redirects are made within the same domain.
• Use a .php file extension for PHP scripts.
• Examine PHP error logs for potential session-related issues.
• Utilize browser developer tools to inspect session cookie values and ensure consistency across requests.
• Check the SameSite attribute on the session cookie, as 'Strict' can cause problems.

Hosting-Related Issues:

If the issue persists after performing the above steps, it may be due to your hosting provider's configuration. Contact your provider for guidance or consult their knowledge base. Some providers require explicit specification of the session save path using session_save_path().
