PHP and WordPress
PHP’s functionality plays a particularly large role when it comes to WordPress development. While it’s possible to build functional WordPress sites without knowing PHP, 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 site’s server and deliver requested content and actions to the user’s screen. If you build a WordPress site using template themes and plugins you’ll still be passively implementing PHP, but in order to create your own themes, plugins, or alter WordPress’ default behavior, you’ll need to develop hands-on PHP skills. WordPress—a content management system that allows you to create and publish digital content online—is a particularly attractive platform for web development since its learning curve make room for complete beginners (who can rely on menu options and default templates), but it keeps the door open for advanced users who can take advantage of PHP and create a more custom experience for clients. Learning your way around WordPress basics alone will already put you in position to do paid WordPress developer work, but learning PHP will make you that much more qualified to carve out a niche as a serious WordPress developer.
