通过php在mysql中实现事务

以下是我的疑问

 $db= new MysqLi('localhost','user','passcode','dbname');
try {
// First of all, let's begin a transaction
$db->beginTransaction();

// A set of queries; if one fails, an exception should be thrown
$query1="insert into table1(id,name) values('1','Dan')";
$query2="insert into table2(id,name) values('2','Anaba')";

// If we arrive here, it means that no exception was thrown
// i.e. no query has Failed, and we can commit the transaction
$db->commit();

} catch (Exception $e) {
// An exception has been thrown
// We must rollback the transaction
$db->rollback();
}

请问我试图通过PHP在mySQL查询中实现事务,我想在其中一个查询失败时失败所有查询.上面的代码抛出一个错误(“致命错误：调用未定义的方法MysqLi :: beginTransaction()”).请有任何更好的解决方案或想法来解决问题.谢谢你的帮助

解决方法:

$db->begin_transaction();

不

$db->beginTransaction();

如果早于PHP 5.5,那么使用

$db->autocommit(true);
