function install_blog($blog_id, $blog_title = '') {}
Install an empty blog.
Creates the new blog tables and options. If calling this function directly, be sure to use switch_to_blog() first, so that $wpdb points to the new blog.
Parameters
- int $blog_id: The value returned by insert_blog().
- string $blog_title: The title of the new site.
