PHP is one of the most knowing programming languages used for web development.
PHP (recursive acronym for PHP: Hypertext Preprocessor) is a widely used open-source general-purpose scripting language that is especially suited for web development and can be embedded into HTML.
PHP is a Scripting Language
Scripting languages like PHP are distinct from markup languages like HTML and CSS in the sense that while HTML and CSS determine the layout and look of web pages, scripting languages tell a static web page (built with HTML and CSS) to “do” specific actions.
PHP is used for Server-Side Scripting
The term client-side refers to website activity that takes place locally on a user’s computer through the user’s web browser.
Client-side means what you see when you are using the internet.
Server-side activity involves a web browser sending requests to a web server, which then responds to the request with HTML code that can be processed and rendered by the web browser and turned into content on the user’s screen.
A server-side scripting language like PHP is used to request content from a website’s server or database and make that content visible and accessible for the website’s user.
PHP and WordPress
PHP functionality plays a particularly large role when it comes to WordPress development.
While it is possible to build functional WordPress websites without knowing PHP.
Within WordPress, PHP is the engine behind custom WordPress themes and plugins.
When creating these kinds of custom WordPress features, PHP is the scripting language used to communicate with the WordPress websites server and deliver requested content and actions to the user’s screen.
If you build a WordPress website using template themes and plugins you will still be passively implementing PHP.
To create your own themes, plugins, or even alter the WordPress default behavior, you will need to develop hands-on PHP skills.
WordPress is a content management system that allows you to create and publish digital content online.
Taking advantage of learning PHP will make you more qualified to carve out a niche as a serious WordPress developer.
PHP will give you access to the lucrative world of WordPress customization.
WordPress Themes and Plugins are written with PHP.
