Default: array()

array[] An empty array if the installation is considered "large" via wp_is_large_network() . Otherwise, an associative array of WP_Site data as arrays.

If wp_is_large_network() returns TRUE, wp_get_sites() will return an empty array. By default wp_is_large_network() returns TRUE if there are 10,000 or more sites in your network. This can be filtered using the wp_is_large_network filter.

Each site’s array is composed entirely of string values, even for numeric values. This means that == or !=, not === or !==, should be used to compare [blog_id] to get_current_blog_id() , which returns an integer value.
