在PHP中如何在12小时和24小时之间转换? [英] How do you convert between 12 hour time and 24 hour time in PHP?

问题描述

我有一个时间作为字符串，例如:

I have a time as a string, for example:

$time = '5:36 pm';

我要求此格式为24小时格式(即17:36)，但是我不知道我需要使用哪些函数对其进行转换.请帮忙.

I require this to be in 24 hour format (i.e. 17:36), however I don't know which functions I need to use to convert it. Please help.

推荐答案

// 24-hour time to 12-hour time 
$time_in_12_hour_format  = date("g:i a", strtotime("13:30"));

// 12-hour time to 24-hour time 
$time_in_24_hour_format  = date("H:i", strtotime("1:30 PM"));
