    this function returns FALSE when you have an error in your syntax in one of your queries, so be carefull with this type of construction when tracking errors:

    <?php

    //error in the second sub query 
    $result = $db->multi_query("select * from news; seleeeeeeect id from news; update news set title='new title' where id= 12 ");

    //code inside object class
    $this->_db = new Mysqli($host, $user, $password, $database, $port, $socket);
           
    do {
            $result = $this->_db->store_result();
            $this->_resultMulti[] = $result;
            $this->_errnoMulti[] = $this->_db->errno;

        if(    is_object($result)) {
                $result->free_result();
        }
                   
    } while(    $this->_db->next_result());

    ?>

    in this construction all you have in the $this->_errnoMulti is :

    array(1) {
      [0]=>
      int(0)
    }

    which means that there are no errors if you are not checking how many queries are executed!
