我有一个计算biorythm的脚本，并显示带有结果的图表。 对于我不知道的原因，在服务器更新后，以下脚本似乎不起作用。

执行后，会发生以下情况：
网关没有收到来自上游服务器或应用程序的及时响应
它或者脚本导致空白页面。
我不认为服务器在执行此脚本时应该花费那么多时间，但是这可能只是我的编码错误。
超时的一个例子就是执行： http://tuttoblog.com/bioritmo/（只需插入随机名称和年份并执行）
空白页面的一个例子就是在这里执行： http://magnaromagna.it/bioritmo/（只需插入随机名称和年份然后执行）
由于我的时间很短，所以对此事的任何帮助都会非常感激。

答案 0 :(得分：0)
尝试推杆：
set_time_limit(300);
在页面顶部，在其余PHP代码之前。看看你的脚本是否能正常执行 - 你应该尽可能减少脚本执行的时间，即使这确实解决了它。
编辑：我有一种感觉不行，因为它可能不是PHP有超时问题。如果这没有帮助，那么它可能与您的服务器设置方式有关，您需要解决这个问题，或者让其他人这样做。
