get_site_option() │ WP 2.8.0

Gets the specified option of the main site of the current network.

Such options are stored in the meta-fields of the network sites - table wp_sitemeta.

The function is very similar to the basic get_option(), only it retrieves data from the wp_sitemeta table, not from wp_options.

This is a wrapper for the get_network_option() function, so read the detailed description at the link.

Control is passed to get_option() when multisite mode is not used.

No Hooks.

Mixed. The value of the option.

get_site_option( $option, $default );

$option(string) (required): The name of the option to retrieve. Expects an unprepared string for SQL query.
$default(mixed): The value to return if the option does not exist.
Default: false
$deprecated(boolean): Deprecated since version 4.4.0. Whether to use cache. Only for multisites.
Default: true

$admin_email = get_site_option( 'admin_email' );

echo get_site_option( 'siteurl' );

$value = get_site_option( 'i_dont_exist' );

// $value == false

$value = get_site_option( 'i_dont_exist', 'blah' );

// $value == 'blah'
