Introduction to PHP - A Popular Programming Language

PHP is an acronym for Personal Home Page or Hyper Text Pre-processor. So from this you can understand that, this is some thing to do with web development. Yes, you're right! PHP is a scripting language and usually embedded with the HTML (Hyper Text Mark-up Language).

PHP was developed by The PHP group and was designed by Rasmus Lerdorf in the year 1995; PHP2.0 was released in the year 1997. A PHP file usually has .php extensions. Rasmus Lerdorf designed PHP to handle usage logging and to create server side forms, later he developed it for large web based projects.

PHP was mainly designed in order to provide the dynamic web pages and it mainly focuses on the server side scripting. When the PHP code is given as an input to the web server it gives HTML content as the output.

PHP runs almost on any web servers and it is free software. It is also easy to implement and use, the code is in the human readable form. These make an advantage to PHP. This scripting language not just focuses on server side scripting but also executes the scripts and is used to generate the graphic user interface (GUI) on client side.PHP is an ideal tool for search engines. PHP with MySQL can be used to access any type of data. Since the PHP has quite a number of extensions it helps in easy data interaction.

Some of the main advantages of PHP are such as; it can be operated in cross platforms, it can run on almost all the servers, rich text processing, and compatible with large number of database. PHP is easy to use; you just need to know the basics of programming and knowledge on C language.
