Sometimes if you want to install a new PHP CMS, blog, wiki, ... you first need to create the necessary database. The installation packages contains the sql file you need to execute, however if you don't have any web based management tool then it can take a bit more time. In this article we will create a simple PHP solution which can execute any sql script on your MySQL database.
SQLite is a C library that implements an embeddable SQL database engine. Scripts which link with the SQLite library can have SQL access without running an additional database server.
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).
