范例

Example #1 MysqlndUhConnection::nextResult() example

<?phpclass proxy extends MysqlndUhConnection { public function nextResult($res) {  printf("%s(%s)\n", __METHOD__, var_export(func_get_args(), true));  $ret = parent::nextResult($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->multi_query("SELECT 1 AS _one; SELECT 2 AS _two");do {  $res = $mysqli->store_result();  var_dump($res->fetch_assoc());  printf("%s\n", str_repeat("-", 40));} while ($mysqli->more_results() && $mysqli->next_result());?>

以上例程会输出：

array(1) {
  ["_one"]=>
  string(1) "1"
}
----------------------------------------
proxy::nextResult(array (
  0 => NULL,
))
proxy::nextResult returns true
array(1) {
  ["_two"]=>
  string(1) "2"
}
----------------------------------------
