<?php

$time_interval = $time->reservation_time_interval; //if 15 min
$dateTime = new DateTime($_GET['date'].$_GET['time']); //if 12:00 am
$dateTime->modify("-$time_interval min");
$date_pre= $dateTime->format('Y-m-d');
$time_pre= $dateTime->format('h:i a');

$dateTime = new DateTime($time_pre);
$dateTime->modify("-$time_interval min");
$time_pre1= $dateTime->format('h:i a');

$dateTime = new DateTime($_GET['time']);
$dateTime->modify("$time_interval min");
$time_post= $dateTime->format('h:i a');

$dateTime = new DateTime($time_post);
$dateTime->modify("$time_interval min");
$time_post1= $dateTime->format('h:i a');

echo $time_pre;echo $time_pre1;echo $time_post;echo $time_post;
?>

当您打印时，您会得到这个= 11:30 pm 11:45 pm 12:15 am 12:30 am
