 function __construct()
    {
      // open db
      $this->db = new mysqli(DB_HOST, DB_USER, DB_PASSWORD, DB_DATABASE);
      if (!$this->db)
        die(mysql_error());

      $this->db->query("SET NAMES 'utf8';");
    }


$result=$this->db->query("SELECT OrgNo, CompanyName FROM ematch WHERE CompanyName LIKE '%$word%';");
           $num=$result->num_rows;
          print $num; 
           $i=0;
            while ($i < $num) 
            {
                 $OrgNo=mysql_result($result,$i,"OrgNo");
                 $CompanyName=mysql_result($result,$i,"CompanyName");
                 $i++;
                 print $OrgNo.' '.$CompanyName.'<br>';
            }

I get this error: Warning: mysql_result(): supplied argument is not a valid MySQL result resource and nothing comes out.
