Understanding home_url()
The home_url() function in WordPress retrieves the home URL for the current site. It is primarily used for linking to the home page of your website. This function dynamically determines the home URL based on the settings specified in the WordPress admin dashboard.
Example of home_url() Usage:
Suppose you want to create a link back to the home page of your WordPress site. You can use home_url() like this:
<a href="<?php echo home_url(); ?>">Home</a>
This code snippet dynamically generates a link to the home page of your website.
Exploring site_url()
On the other hand, the site_url() function retrieves the URL of the WordPress site. It returns the URL where the core WordPress files are stored. This function is useful when you need to reference resources or files within your WordPress installation.
Example of site_url() Usage:
Imagine you need to reference an image stored in your WordPress installation. You can use site_url() as follows:
<img src="<?php echo site_url('/wp-content/uploads/image.jpg'); ?>" alt="Image">
In this example, site_url() generates the URL pointing to the image stored within the ‘wp-content/uploads’ directory of your WordPress site.
