PHP is a scripting language initially designed for producing dynamic web pages. It is widely used for website development and can be embedded into HTML. There are many database applications but PHP programming is very popular due to easy management of website as it is based on CMS. It is server side scripting language (PHP Hypertext Preprocessor) that facilitates the creation of dynamic Web pages by embedding PHP-coded logic in HTML documents. It combines many of the finest features of Perl, C, and Java, and adds its own elements to the concoction to give Web programmers great flexibility and power in designing and implementing dynamic, content-oriented Web pages. PHP programming was originally designed for use in web development, but today, it has rapidly grown as a robust language, which can be changed as per one’s requirements, both for development of system software and development of web based applications alike. This is because it supports different databases like MySQL, Oracle and Sybase.
Although most people use PHP programming language primarily as a Web development scripting system, it possesses all the characteristics of a proper general-purpose language that can be useful in a variety of other environments.
PHP can be run as either a CGI application or as an integrated Web server module. Regardless of its mode of execution, the PHP interpreter has the potential to access virtually every part of the host -- the file system, network interfaces, IPC, etc. Consequently, it has the potential to do (or be forced to do) a lot of damage.
PHP programming has achieved a stable and solid presence on the Web in the last several years, and its popularity as a server-side scripting language is only increasing.
