范例

Example #1 MysqlndUhConnection::useResult() example

  <?php
 class  proxy  extends  MysqlndUhConnection  {
 public function  useResult ( $res ) {
   printf ( "%s(%s)\n" ,  __METHOD__ ,  var_export ( func_get_args (),  true ));
   $ret  =  parent :: useResult ( $res );
   printf ( "%s returns %s\n" ,  __METHOD__ ,  var_export ( $ret ,  true ));
   var_dump ( $ret );
  return  $ret ;
 }
}
 mysqlnd_uh_set_connection_proxy (new  proxy ());

 $mysqli  = new  mysqli ( "localhost" ,  "root" ,  "" ,  "test" );
 $mysqli -> real_query ( "SELECT 'Good morning!' AS _msg FROM DUAL" );
 $res  =  $mysqli -> use_result ();
 var_dump ( $res -> fetch_assoc ());
 ?>

以上例程会输出：

proxy::useResult(array (
  0 => NULL,
))
proxy::useResult returns NULL
resource(425) of type (Mysqlnd Resultset (internal only - you must not modify it!))
array(1) {
  ["_msg"]=>
  string(13) "Good morning!"
}
