   $query = "CALL mp_test1()";
	
   $i = 0;	
	
   if ($mysqli->multi_query($query)) 
   {
    do {		
	/* store first result set */
        if ($result = $mysqli->use_result()) 
	{
	  $j = 0;
	  
          while ($row = $result->fetch_row()) 
	  {
	     $arrResult[$i][$j] = $row[0];
	     $j++;
	  }
				
   	  $result->close();
         }
			
	if($mysqli->more_results()) 
	{
  	  $i = $i + 1;
	}			 
     } while ($mysqli->next_result());
   }
	
   print "
