范例

Example #1 MysqlndUhConnection::moreResults() example

<?php
class proxy extends MysqlndUhConnection {
 public function moreResults($res) {
  printf("%s(%s)\n", __METHOD__, var_export(func_get_args(), true));
  $ret = parent::moreResults($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::moreResults(array (
  0 => NULL,
))
proxy::moreResults returns true
proxy::moreResults(array (
  0 => NULL,
))
proxy::moreResults returns true
array(1) {
  ["_two"]=>
  string(1) "2"
}
----------------------------------------
proxy::moreResults(array (
  0 => NULL,
))
proxy::moreResults returns false
