Both functions return the website url.

And, as home_url() needs sanitization (for example <?php echo esc_url( home_url( '/' ) ); ?>), why it is this snippet of code, instead of <?php echo get_ home_url( '/' ); ?>, that we found in Wordpress Codex and Wordpress Template Twenty Nineteen ?

There isn't much difference but they are not the same.


get_home_url() takes null or a blog id as the first parameter. As per documentation here.

get_home_url( int $blog_id = null, string $path = '', string|null $scheme = null )

If you are dealing with multiple homes (as in, say a multi-site set up) this might be useful.


home_url(), on the other hand, is less fussed about per blog settings and just wants the home URL. As per documentation here.

home_url( string $path = '', string|null $scheme = null )

It is the equivalent of calling get_home_url( null, $path, $scheme );. Most of the time, this is the function you want.

    If i understand you well, as get_home_url() is taking this blog id as a parameter, it makes more sense for a standard wordpress template as Twenty Nineteen to use it in the header.php, cause it could be used in a multisite set up, which is relevant because it's pretty common. Thanks a lot for your very clear and pedagogic answer.

There is no difference. If you look at wordpress code you will see

function home_url( $path = '', $scheme = null ) {
        return get_home_url( null, $path, $scheme );
