php - PHP Mktime 错误

Question

我突然在我已经完成的网站上收到以下错误，到目前为止一直运行良好：

A PHP Error was encountered

Severity: Warning

Message: mktime() [function.mktime]: It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'Antarctica/Macquarie' for 'EST/10.0/no DST' instead

这是有问题的代码：

$stamp=mktime(0,0,0,$month,$day,$year);

这里有什么问题？我怎样才能快速消除这些错误？我mktime在很多地方都使用这种格式，并且在每个地方都会抛出错误。

Answer 1

正如错误所说，您要么需要在代码中使用date_default_timezone_set('Antarctica/Macquarie');or指定时区，要么在.ini_set('date.timezone', 'Antarctica/Macquarie');date.timezonephp.ini

Answer 2

你能确认$month,$day和$year是 INT - 甚至不是 NULL 吗？

还要查看date_default_timezone_set()
