Example #1 MysqlndUhConnection::charsetName() example

  <?php
 class  proxy  extends  MysqlndUhConnection  {
  public function  charsetName ( $res ) {
    printf ( "%s(%s)\n" ,  __METHOD__ ,  var_export ( func_get_args (),  true ));
    $ret  =  parent :: charsetName ( $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" );
 var_dump ( mysqli_character_set_name ( $mysqli ));
 ?>

以上例程会输出：

proxy::charsetName(array (
  0 => NULL,
))
proxy::charsetName returns 'latin1'
string(6) "latin1"
