## 󠀁[Parameters](https://developer.wordpress.org/reference/functions/get_site_option/?output_format=md#parameters)󠁿

 `$option`stringrequired

Name of the option to retrieve. Expected to not be SQL-escaped.

`$default_value`mixedoptional

Value to return if the option doesn’t exist.

Default:`false`

`$deprecated`booloptional

Whether to use cache. Multisite only. Always set to true.

Default:`true`

## 󠀁[Return](https://developer.wordpress.org/reference/functions/get_site_option/?output_format=md#return)󠁿

 mixed Value set for the option.

## 󠀁[More Information](https://developer.wordpress.org/reference/functions/get_site_option/?output_format=md#more-information)󠁿

This function is almost identical to [get_option()](https://codex.wordpress.org/Function_Reference/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()](https://codex.wordpress.org/Function_Reference/get_option)
and [get_site_option()](https://developer.wordpress.org/reference/functions/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()“

    ```php
    function get_site_option( $option, $default_value = false, $deprecated = true ) {
    	return get_network_option( null, $option, $default_value );
    }
