Action(事务)
启动一个事务
action( $callback )
$callback [function]
事务内执行的方法.
Return: void
不是每个数据库引擎都支持事务。你必须在使用前检查。如果返回false，则回滚事务。
$database->action(function($database) {
$database->insert("account", [
"name" => "foo",
"email" => "bar@abc.com"
]);
$database->delete("account", [
"user_id" => 2312
]);
// If you want to find something wrong, just return false to rollback the whole transaction.
if ($database->has("post", ["user_id" => 2312]))
{
return false;
}
});
