How can the session_write_close function be used to resolve PHP session issues, particularly in cases where sessions are not being maintained across different pages or browsers?

When PHP sessions are not being maintained across different pages or browsers, the session_write_close function can be used to explicitly write and close the session data before the script ends. This ensures that the session data is saved and available for retrieval on subsequent pages or browsers.

session_start(); // Start the session
// Perform operations with session data

session_write_close(); // Write and close the session data

// Continue with other code
