25879SQLitehttp://www.phpfive.net/sqlite_introduction_article3.htmSQLite is an embedded database library that implements a large subset of the SQL 92 standard. Its claim to fame is the combination of both the database engine and the interface (to said engine) within a single library, as well as the ability to store all the data in a single file. I terms of functionality SQLite resides somewhere between MySQL and PostgreSQL. However, when it comes to performance, SQLite is often 2-3 times faster (or even more). This is thanks to a highly tuned internal architecture, and the elimination of server-to-clientand client-to-server communication.PHP > Tips and Tutorials > Database-RelatedOct 15, 2006
Firefox, everyones favorite internet browser has now got a new version with all new features and improved old features. You can see a full list of Firefox 2.0 features here.
PHP4 is packed with good features. One of the most popular is session variables. These are variables that persist throughout a session, as the user moves from page to page. Session variables are great holders of state information and other useful stuff.
To use session variables, call session_start() at the beginning of your web page, before your HTTP headers are sent. Then for every variable you want to keep alive for the duration of the session, store it in $_SESSION[$variable_name]. By default, the session handler will keep track of the session by using a cookie. You can save objects or arrays in session variables also (but be warned that this is buggy in some versions of PHP4).
