Rasmus continued adding scripts to his collection so he could do more with his websites. Over time, some friends began to use it as well. As others embraced it, and began to submit their own work, PHP grew. By version 3 it was decided that the time had come for a more professional name. Now with dozens of developers and even more contributors, PHP has grown to version 5, and is installed on tens of millions of servers around the world. It continues to rank as one of the top ten web development languages.

These technologies are named as such because they are performed by the client in the client-server model. A client is a piece of software usually a web browser which operates on the local system and makes Hypertext Transfer Protocol HTTP requests to a server as necessary. Client-side technologies can be faster and safer than server-side technologies; however they are limited in functionality and cannot interact with permanent storage such as a database. If your web-application requires permanent storage, for example you want users to add to an existing dataset or pull information that is stored centrally, server-side technologies are required to complete these processes. The term 'server-side technologies' can encompass a range of software solutions, mainly: server-side scripting languages; Database Management Systems DBMS ; web server software such as Apache; and many other technologies depending upon the application being built.
