The Reasons Behind Our Plugins
The most important rule in WordPress development is to avoid tampering with the core of the platform. This implies that adding functionality to your website doesn’t require editing core WordPress files. This is due to the fact that every update causes WordPress to overwrite essential files. Plugins should be used to add or change any feature.
Depending on what you want to do, WordPress plugins can be as basic or as complex as necessary. One PHP file is the most basic kind of plugin. One example of such a plugin is the Hello Dolly plugin. Only a Plugin Header, a few PHP functions, and a few hooks to attach your functions to are required by the plugin PHP code.
What is Plugin?
Plugins are code bundles that add functionality to WordPress’s fundamental features. PHP code makes up WordPress plugins, which may also contain additional resources like CSS, JavaScript, and pictures.
A plugin actually only requires one primary file with a specially structured DocBlock in the header, although the majority of WordPress plugins are made up of numerous files.
Just 100 lines make up Hello Dolly, one of the original plugins. The WordPress administrator displays the lyrics of the well-known song “Hello Dolly.” The PHP file uses some CSS to manage the lyric’s style.
