get_home_url()

get_home_url() — Retrieves the URL for a given site where the front end is accessible. Returns the ‘home’ option with the appropriate protocol. The protocol will be ‘https’ if is_ssl() evaluates to true; otherwise, it will be the same as the ‘home’ option. If $scheme is ‘http’ or ‘https’, is_ssl() is overridden.

Inputs: $blog_id (int|null): Optional. Site ID. Default null (current site). $path (string): Optional. Path relative to the home URL. Default empty. $scheme (string|null): Optional. Scheme to give the home URL context. Accepts ‘http’, ‘https’, ‘relative’, ‘rest’, or null. Default null.

Returns string: Home URL link with optional path appended.
