How to check if time is between two times in PHP
提问by user966582
I have following three strings (current time, sunset and sunrise), how can I find if the current time is between the sunrise and sunset?
我有以下三个字符串（当前时间，日落和日出），如何确定当前时间是否在日出和日落之间？
$current_time = "10:59 pm";
$sunrise = "5:42 am";
$sunset = "6:26 pm";
回答by John Conde
$current_time = "4:59 pm";
$sunrise = "5:42 am";
$sunset = "6:26 pm";
$date1 = DateTime::createFromFormat('H:i a', $current_time);
$date2 = DateTime::createFromFormat('H:i a', $sunrise);
$date3 = DateTime::createFromFormat('H:i a', $sunset);
if ($date1 > $date2 && $date1 < $date3)
{
echo 'here';
}

i would recoment you to first "convert" the strings to integers using substr function and intval.
我建议您首先使用 substr 函数和 intval 将字符串“转换”为整数。
avter this step you should be able to simply compare the times.
在这一步之后，您应该能够简单地比较时间。
( note that you should use 18:00 instead of 6:00 PM, this would be easyer to handl, therefor you could "detect" with substr if the time is AM or PM, and just add "12" to the number )
（请注意，您应该使用 18:00 而不是 6:00 PM，这会更容易处理，因此如果时间是 AM 或 PM，您可以使用 substr“检测”，然后将“12”添加到数字中）
i'm pretty shure there are more elegant ways of doing this, but this should just give you an BASIC idea for a SIMPLE way for not advanced php developers.
我很确定有更优雅的方法可以做到这一点，但这应该只是为您提供一个基本的想法，为非高级 php 开发人员提供一种简单的方法。
hope it helps
