SimpleXMLIterator性能PHP
我有以下三个与AmazonAPI交互的函数。当我使用parse_orders_result函数时，似乎需要大约30秒才能完成。我通过运行get_orders函数发现了这一点，并注释掉了parse_orders结果，它在3秒内完成了do while循环的每个迭代。然而，当我运行解析程序时，需要花费我在下面提到的30秒。如何提高此操作的性能 获取订单功能：SimpleXMLIterator性能PHP,php,performance,simplexml,Php,Performance,Simplexml,我有以下三个与AmazonAPI交互的函数。当我使用parse_orders_result函数时，似乎需要大约30秒才能完成。我通过运行get_orders函数发现了这一点，并注释掉了parse_orders结果，它在3秒内完成了do while循环的每个迭代。然而，当我运行解析程序时，需要花费我在下面提到的30秒。如何提高此操作的性能 获取订单功能： public function get_orders($date) { $this->throttle =

请度量每行代码，执行频率，每次执行平均花费的时间以及每行代码的总数。然后，请在问题代码中标出30秒的确切时间。您可以使用Xdebug进行分析。30秒是常见的网络超时（另一个通常为10秒）。如果您有30.5秒的时间来编写一段代码，那么其中可能有一个网络功能失败（例如GET或POST），失败需要30秒，处理需要0.5秒。我认为问题可能出在数据库交互中。它在$shipping_方法中选择相同的数据，在每次迭代中选择$order_状态行，尽管这是相对静态的信息，可以在循环之外选择。此外，我还编写了另一个merge语句函数，它接受多维数组中的所有项，并在单个IO操作中一次性合并它们（而不是在每次迭代中执行单个merge语句）。我将在测试这些更新的效率后进行回复。
