PHP is a free and open source programming language developed specifically for use on websites.
It's an extremely popular language, used to power over 20 million web sites (Netcraft survey, April 2007).
The reasons we use PHP are:
- It's easy to install and configure, so you can get started writing code in no time
- It's easy to learn
- It has loads of inbuilt functionality, especially for websites
- It has an exceptional online manual
- It has a strong global user community
- It's doubly free (free as in freedom, and free as in beer) so you can install as many different versions of it on as many different servers as you want
Who uses PHP? Some examples are Facebook, Wikipedia, and Digg
