get_home_url retrieves the Home Page URL of a WordPress website. get_home_url is one of the most used WordPress functions by developers when they want to use links in the development process. Let's have a better look at this function with an example.
WordPress can be installed on any sub-directory in your website host.
Not all of the time WordPress is installed on the root folder, so it becomes important to have a function returning the current website’s URL.
When you are developing WordPress themes or plugins, Using relative addresses for file reference or link building is NOT a great idea.
You should never use fixed URLs also!
The reason is clear, addresses may change due to differences in WordPress installation, selected options, and etc.
A good practice for making a linked reference to a website is using the get_home_url function in PHP.
