apply_filters( 'pre_get_site_by_path', null|false|WP_Site $site, string $domain, string $path, int|null $segments, string[] $paths )

Determine a site by its domain and path.

Description

This allows one to short-circuit the default logic, perhaps by replacing it with a routine that is more optimal for your setup.

Return null to avoid the short-circuit. Return false if no site can be found at the requested domain and path. Otherwise, return a site object.

$site: (null|false|WP_Site) Site value to return by path. Default null to continue retrieving the site.
$domain: (string) The requested domain.
$path: (string) The requested path, in full.
$segments: (int|null) The suggested number of paths to consult. Default null, meaning the entire path was to be consulted.
$paths: (string[]) The paths to search for, based on $path and $segments.
