范例
Example #1 MysqlndUhConnection::stmtInit() example
<?phpclass proxy extends MysqlndUhConnection { public function stmtInit($res) { printf("%s(%s)\n", __METHOD__, var_export(func_get_args(), true)); var_dump($res); $ret = parent::stmtInit($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");$stmt = $mysqli->prepare("SELECT 1 AS _one FROM DUAL");$stmt->execute();$one = NULL;$stmt->bind_result($one);$stmt->fetch();var_dump($one);?>
以上例程会输出：
proxy::stmtInit(array ( 0 => NULL, )) resource(19) of type (Mysqlnd Connection) proxy::stmtInit returns NULL resource(246) of type (Mysqlnd Prepared Statement (internal only - you must not modify it!)) int(1)
