A complete overview of PHP session handler life cycle
The purpose of this document is to provide a complete overview of the PHP session
handler life cycle updated to version 7.0 or above. In particular, I want to
emphasize what methods and in what order are called when the native PHP functions
are used for session management.
I created this document because the information on the web and the official documentation are very superficial on this topic, in particular on what concerns the implementation of a safe and stable session handler.
