What is PHP ?


PHP is the most popular development language for the Web, with over 30 million domain namesĀ using it. It is an open source, cross platform language that supports all modern programming language functionality.

PHP = open source

PHP has been an open source language since its creation by Rasmus Lerdorf in 1995. Ever since, thousands of developers worldwide have worked on improving and expanding the language.

The open source nature and the large number of developers of the language has allowed it to adopt new technology, new features and hot new trends faster than any other language.

The strength of PHP

Unlike other commonly used development languages, PHP was built specifically for the Web. From the basic design to the specific network implementation, when building Web applications PHP is often the logical choice.

PHP is most often used in combination with the operating system Linux, the webserver software Apache and the database server MySQL, all of which are also open source. However, in recent years, this combination has become less standard, with a wide variety of alternatives being available, allowing consultancy providers to build the most fitting solution for each customer.

PHP = hot

Don't take our word for it... consider the following names who run their entire Web presence on PHP : BBC, Yahoo, Wikipedia, UPS, Facebook, Wordpress, Flickr, IBM, HP, NASA, Orange, BT, ...

PHP = professional

There used to be a time when PHP was considered as a language for hobbyists. The reason : there was hardly any formal training, no certification program and no large corporations supporting its development.

Ever since PHP4 was released, the momentum has shifted significantly. Big corporations are not just using PHP, but are actively developing the language. And just like many other languages, PHP has a certification program.
