PHP is an all-in-one general-purpose programming language aimed at web development. It was first developed by Danish-American developer Rasmus Lerdorf in 1994 with the aim of using it as a programming language for the web. The PHP source code implementation has been taken over by The PHP group now. The major characteristics of PHP are its high level of standardisation, relative simplicity and robustness when compared to other common web development languages.
PHP is used to power most of the dynamic visual features of a website, starting from the HTML codes to the various image libraries such as the JPEG or GIF image files. The PHP programming language can also be mixed with other programming languages, which is made possible by the use of "underscoding". In PHP, the programmer can specify complex expressions by means of "various" pre-processing rules. Some of the most famous PHP libraries such as the PHPEnderer, PHPExtractor and the Xbench can automate many common web applications.
One of the major reasons why PHP code web development has become so popular nowadays is because of the community support provided by the PHP project. With the help of the community support, the PHP website development process can be smoothly handled by developers belonging to all different areas and communities of PHP users. The biggest advantage of using PHP for PHP website development is the fact that PHP code web development is free. The PHP source code of different websites is openly available to all. The PHP website development community is actively involved in the maintenance of the PHP website and provide constant free support for PHP users.
