apply_filters( "pre_site_option_{$option}", mixed $pre_option, string $option, int $network_id, mixed $default )

Filters the value of an existing network option before it is retrieved.

The dynamic portion of the hook name, $option, refers to the option name.

Returning a truthy value from the filter will effectively short-circuit retrieval and return the passed value instead.

$pre_option: (mixed) The value to return instead of the option value. This differs from $default, which is used as the fallback value in the event the option doesn't exist elsewhere in get_network_option(). Default false (to skip past the short-circuit).
$option: (string) Option name.
$network_id: (int) ID of the network.
$default: (mixed) The fallback value to return if the option does not exist. Default false.
