PHP (PHP: Hypertext Preprocessor) is a scripting language that helps make webpages more interactive by allowing them to do more things. For example, a website programmed with PHP can have pages that are password protected, whereas a website with no programming can not do this without other complex things. Standard PHP file extensions are: .php .php3 or .phtml, although a webserver can be set up to use any extension.[3][dubious ] Its structure was influenced by many languages like C, Perl, Java, C++, and even Python. It is considered to be free software by mean of the Free Software Foundation.[4]
Wikipedia, which runs on MediaWiki, uses the PHP scripting language.[5]
