Hypertext Preprocessor, usually the recursive abbreviation PHP is used. It is one of the most widely used programming languages. It is an open source scripting language. PHP is running on the server side, which means that PHP scripts are executed on the server that processes them. Only after that, it sends to the client pure HTML code. PHP commands are inserted directly into the HTML code and are separated from it by paired tags <?php and ?> or <? and ?>.
PHP was created in 1994 by Rasmus Lerdorf.
Use of PHP in practice: PHP is primarily used for creating dynamic websites. Programming in PHP is relatively simple and contains a huge range of functions. With PHP, it can be programmed, for example corporate websites, e-shop or a custom content management system, including forms processing, statistics, search or advertising system. Text files or more databases are used to store data (PHP supports most commonly used databases such as MySQL, PostgreSQL, Oracle Database, DB2).
To accelerate the development in PHP the PHP Frameworks are used.
