is_plugin_active_for_network( string $plugin )
Determines whether the plugin is active for the entire network.
Description
Only plugins installed in the plugins/ folder can be active.
Plugins in the mu-plugins/ folder can’t be "activated," so this function will return false for those plugins.

Parameters
- $plugin
-
(string) (Required) Path to the plugin file relative to the plugins directory.

(bool) True if active for the network, otherwise false.
