计算php中特定日期时间剩余的时间

Question

我可以知道如何计算php中特定日期时间剩余的时间吗？

示例我希望用户可以在30分钟后请求新的确认码。

$request_date = '2012-03-24 13:03:17';
$please_wait  = '30 minutes';

如何计算剩余时间？

Answer 1

strtotime("+" . $please_wait, strtotime($request_date));

尝试

php> $request_date = '2012-03-24 13:03:17';

php> $please_wait  = '30 minutes';

php> echo strtotime("+" . $please_wait, strtotime($request_date));
1332576197

Answer 2

$thirty_minutes_in_the_future = strtotime('+30 minutes', strtotime($request_date));

Answer 3

计算请求的时间戳并用当前时间戳减去

解决方案：

$future = strtotime($request_date)+1800; // 1800 is 30 minutes
echo date("i", $future-time()); //this is the remaining minutes

Answer 4

新确认码的剩余时间：

$request_date = '2012-03-24 13:03:17';
$please_wait  = '30 minutes';
$future_time = strtotime("+" . $please_wait, strtotime($request_date));
$time_left = $future_time - time(); //seconds left
