PHP Sessions overview

HTML and web servers by default don't keep track of information that was entered on a page when the client's browser loads another page. This makes doing anything that involves using the same information from a user on several pages difficult.

Sessions help solve this problem by maintaining data during a user's visit to your web site from page to page on your site. Each session can store many variables that are maintained throughout that session. The server keeps track of users' sessions by assigning them a unique session ID, generated by the server, when the session starts. This identifier is called the session identifier and must be sent to the server each time a page is requested once a session begins.
