Terminating a Session

There are times when it is necessary (and good practice) to terminate a session and destroy all data
associated with the current session. The function session_destroy is responsible for handling the described
actions; however, this function is limited in its ability by not unsetting (or clearing) the global variables tied
to the session or the respective cookies. This requires a more detailed approach:

<?php
session_start();
// Unset all session variables
$_SESSION = array();
// Unset all cookie variables
if(isset($_COOKIE[session_name()])){
setcookie(session_name(),'', time()-48000,'/');
}
?>

MySQL General Architecture

        MySQL operates in a networked environment using a client/server architecture. In other words, a central  program acts as a server, and various client programs connect to the server to make requests. A MySQL  installation has the following major components: MySQL Server, Client programs and MySQL non client  utilities.  MySQL Server MySQL Server, or mysqld, is the database server program. The server manages access to the actual  database (schema) on disk and in memory. MySQL Server is multi-threaded and supports many  simultaneous client connections. Clients can connect via several connection protocols. For managing  database contents, the MySQL server features a modular architecture that supports multiple storage engines  that handle different types of tables (for example, it supports both transactional and non-transactional  tables). Keep in mind the difference between a server and a host. The server is s...
