WP_Network::get_by_path( string $domain = '', string $path = '', int|null $segments = null )
Retrieve the closest matching network for a domain and path.
Description
This will not necessarily return an exact match for a domain and path. Instead, it breaks the domain and path into pieces that are then used to match the closest possibility from a query.
The intent of this method is to match a network during bootstrap for a requested site address.
Parameters
- $domain
-
(Optional) Domain to check.
Default value: ''
- $path
-
(Optional) Path to check.
Default value: ''
- $segments
-
(Optional) Path segments to use. Defaults to null, or the full path.
Default value: null
Return
(WP_Network|bool) Network object if successful. False when no network is found.
