 public function 
getAffectedRows ( $res ) {
   
printf ( "%s(%s)\n" __METHOD__ var_export ( func_get_args (),  true ));
   
$ret  parent :: getAffectedRows ( $res );
   
printf ( "%s returns %s\n" __METHOD__ var_export ( $ret true ));
   return 
$ret ;
 }
}
mysqlnd_uh_set_connection_proxy (new  proxy ());

$mysqli  = new  mysqli ( "localhost" "root" "" "test" );
$mysqli -> query ( "DROP TABLE IF EXISTS test" );
$mysqli -> query ( "CREATE TABLE test(id INT)" );
$mysqli -> query ( "INSERT INTO test(id) VALUES (1)" );
var_dump ( $mysqli -> affected_rows );
?>
