如何在php中计算时间

Question

help me in calculating exact time with AM and PM

$time1 = strtotime(10:00); /// in pm 
$time1 = strtotime(08:00); ///// answer should come in am calculation
                                 is exact but not the am pm value
$count = date ('g:i ' ,strtotime($time1 . '+' . $time2));

My Problem is if i calculate time i calculate it correctly as i want but how can i set the PM and AM to time if i take 10:00 PM time add 4 hour to it now time is 02:00 AM how to get that AM PM value with time and any help with subtract time how we subtract time

Use DateTime to deal with Dates and Times with less hassle.

<?php
$time = new DateTime("10am"); // assumes 10am today
$time->modify("+4 hours");
echo $time->format("g:i A"); // outputs 2:00 PM

See the DateTime book by the author of the DateTime extension.
