What is PHP? What is WordPress? What are their uses? Are they the same? In what way is it necessary to have these languages? What would happen if we do not use PHP or WordPress?
PHP is a server language used to create interactive websites. WordPress is coded by using PHP as the reference language or basis. Both PHP and WordPress are open source languages. Their use is to collect information from the users. For example, the contact forms, query forms, etc. are developed by using these languages. They take the information input from the user and store this same information on the server for later use. If we do not use these languages, we will not be able to save contact information and no forms will be able to be processed or submitted.
PHP is the short term for PHP: Hypertext Preprocessor. It is a widely used open source general-purpose scripting language that is suitable for use on web development and can also be embedded into HTML. It is a server-side scripting language intended for web development but is also used as a general-purpose programming language.
PHP was originally created by Rasmus Lerdorf back in 1994 and the PHP reference implementation is currently produced by The PHP Group. Instead of using tons of commands to output HTML like with Perl and C, PHP pages have HTML with embedded code that does something like output the message “Hi, I'm a PHP script!” like in the image above.
The PHP code is enclosed in special start and end processing instructions (“”). This start and end processing instructions lets you jump in and out of PHP mode. The difference between PHP and client-side JavaScript is that the code is launched on the server that produces HTML which is then sent to the client or the web browser.
The client will receive the output of the running script but would not know what the underlying or original code was. You can also configure your web server to process all your HTML files with PHP and there is actually no way the user will know what you have up your sleeve.
This is probably of the reasons why the majority of the websites use PHP in their HTML files. WordPress, on the other hand, is a free open source CMS or Content Management System that is based on MySQL and PHP.
It is installed on a web server which is either part of a web hosting service like with the service provided by WordPress.com, or is a network host itself like a computer running the WordPress.org software package.
