大佬教程收集整理的这篇文章主要介绍了php – 计算两个日期时间之间的差异，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

<?PHP
    $start_time = "Y-m-d H:i:s"; // fill this in with actual time in this format
    $end_time = "Y-m-d H:i:s"; // fill this in with actual time in this format

    // both of the above formats are the same as what MysqL stores its
    // datetiR_514_11845@Es in

    $start = new datetiR_514_11845@e($start_timE);
    $interval = $start->diff(new datetiR_514_11845@e($end_timE));

    echo $interval->format("d \d\a\y\s h \h\o\u\r\s");
