Set just one shared website

Like, how can I set just a specif blog id to be shared on this code? Or should I change another peace of it? Tks!

function __construct() {
global $blog_id;
$this->current_blog_id = $blog_id;

/* copied from depricated get_blog_list */
global $wpdb;
$blogs = $wpdb->get_results( $wpdb->prepare(“SELECT blog_id, domain, path FROM $wpdb->blogs WHERE site_id = %d AND public = ‘1’ AND archived = ‘0’ AND spam = ‘0’ AND deleted = ‘0’ ORDER BY registered DESC”, $wpdb->siteid), ARRAY_A );

$this->blogs = array();
$sort_array = array();

foreach ( (array) $blogs as $details ) {
if ( !current_user_can_for_blog( $details[‘blog_id’], ‘upload_files’) || $details[‘blog_id’] == $this->current_blog_id ) continue;

$details[‘name’] = get_blog_option( $details[‘blog_id’], ‘blogname’ );
$this->blogs[] = $details;
$sort_array[] = strtolower ( $details[‘name’] );
}
array_multisort( $sort_array, SORT_ASC, $this->blogs );
}
