2. What You Will Need?

Before going ahead in the next step, first you will have to install all the necessary software required for developing and testing the script. So, first install and configure your system from the following software:

For testing the script on local server install Apache http server or WAMP Server for Windows machines; LAMP server for Linux machine; and MAMP server for MAC machine. These servers can be freely downloaded from the internet:

       http://httpd.apache.org/docs/2.0/en/install.html for Apache http server;
       www.wampserver.com/en/ for WAMP server;
       http://www.sawmac.com/mamp/ for MAMP server;

       The installation of LAMP server depends upon the Linux Distro. For instance
       download and install LAMP server for Ubuntu from
       http://www.ubuntugeek.com/ubuntu-710-gutsy-gibbon-lamp-server-setup.html

Install the latest version of PHP, Currently PHP 5.2.10 and 5.3.0 is popular

For the database install MySQL

You can also test your PHP script on web server which you have hosted, but it is very panic and needs FTP or telnet in every time you want to change something.
