$option string Required: Name of the option to retrieve. Expected to not be SQL-escaped.

$deprecated bool Optional: Whether to use cache. Multisite only. Always set to true.

Default: true

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()“
