This page provides a full overview of PHP's SessionHandler life-cycle - this was generated by a set of test-scripts, in order to provide an exact overview of when and what you can expect will be called in your custom SessionHandler implementation.

Each example is a separate script being run by a client with cookies enabled.

To the left, you can see the function being called in your script, and to the right, you can see the resulting calls being made to a custom session-handler registed using session_set_save_handler().
