This document provides an overview and agenda for a PHP session that covers key topics like application organization, superglobals like $_GET and $_POST, sessions, and dates and times in PHP. It explains that superglobals are available everywhere and are commonly attacked, and that $_GET is for read-only data while $_POST is for modifying data on the server. Sessions are introduced as a way to track user information across requests by assigning each user an ID and cookie, with data stored on the server. Basic functions for working with dates and times in PHP like time(), date(), mktime(), and strtotime() are also summarized.
