PHP 脚本运行良好。加载大约需要0.03。 但是当脚本到达 CalendarExpiryItemList 类时。大约需要 30 秒，我的服务器超时。
每个表平均有大约 12 到 15 个字段和大约 10 到 100 条记录。
我正在托管一家托管公司，他们有负载均衡器。因此，如果我的脚本花费的时间超过 30 秒，负载均衡器会重置我的连接并返回一条错误消息“服务器未发送数据”

在Ruby(尤其是Rails)中，您经常需要检查某物是否存在，然后对其执行操作，例如:if@objects.any?puts"Wehavetheseobjects:"@objects.each{|o|puts"hello:#{o}"end这是最短的，一切都很好，但是如果你有@objects.some_association.something.hit_database.process而不是@objects呢？我将不得不在if表达式中重复两次，如果我不知道实现细节并且方法调用很昂贵怎么办？显而易见的选择是创建一个变量，然后测试它，然后处理它，但是你必须想出一个变量名(呃)，它也会在内存中
