The clean_network_cache() WordPress PHP function removes a network or multiple networks from the object cache.
Usage
To use the clean_network_cache() function, you simply need to pass the ID of the network or an array of network IDs that you want to remove from the cache.
clean_network_cache( $ids );
Let’s say we have two networks with IDs 1 and 2, and we want to remove both of them from the cache. Here is how you can do it:
clean_network_cache( array(1, 2) );
Parameters
- $ids (int|array): Required. The Network ID or an array of Network IDs to remove from the cache.

Examples
Removing a Single Network from Cache
This example removes a network with the ID of 1 from the object cache.
// Remove network with ID 1 from cache clean_network_cache(1);
Removing Multiple Networks from Cache
This example removes networks with IDs 1, 2, and 3 from the object cache.
// Remove networks with IDs 1, 2, 3 from cache clean_network_cache(array(1, 2, 3));
Removing All Networks from Cache
This example removes all networks from the object cache by getting all network IDs first.
// Get all network IDs $network_ids = get_all_network_ids(); // Remove all networks from cache clean_network_cache($network_ids);
Cleaning Cache after Creating a Network
After creating a new network, you might want to clean the cache to ensure the new network is not cached yet.
// Create a new network
$network_id = wp_create_network('Network Name', 'http://example.com');
// Remove the new network from cache
clean_network_cache($network_id);
Cleaning Cache after Deleting a Network
After deleting a network, it’s a good practice to clean the cache to remove any traces of the deleted network.
// Delete a network wp_delete_network(1); // Remove the deleted network from cache clean_network_cache(1);
