Question

我在这里有一些简单的代码来比较日期和数量产品，除了8月和9月之外，它适用于我所有月份。我已经过了十几次，所有月份的一切看起来都一样，但八月和九月的日期都没有找到，其他日期测试OK。

对不起蹩脚的代码，我还是初学者。

提前致谢

Answer 1

你有这些变量：

$augmonth_stop = 20170831;
$september_stop = 20170930;

但正在检查不同的东西：

($ship_date <= $augmonth_end)
($ship_date <= $september_end)

修复一个或另一个，你的代码应该有用。

也就是说，考虑使用一些PHP内置日期函数，比如strtotime()，或者更好地为你的应用程序使用DateTime类。

日期comparson代码无法找到8月和9月的日期
