More Information

This function is almost identical to get_option(), except that in multisite, it returns the network-wide option. For non-multisite installs, it uses get_option.

It is easy to get confused about the difference between get_option() and get_site_option(), because multisite used different terms before. Now there are different “sites” on a “network”, before there where different “blogs” on a “site”. Many functions and variables were introduced before this change, such as this one. Think of this function as “get_network_option()


File: wp-includes/option.php

function get_site_option( $option, $default = false, $deprecated = true ) {
	return get_network_option( null, $option, $default );
