Question

我在php中有两个日期变量

$ var1和$ var2

var1包含一些过去时间，var2包含当前时间。我想计算相对时间，例如3小时前，5天前等等。

我已经被困了很长一段时间。任何人都可以帮忙

我已经提到了有关此问题的现有stackoverflow帖子，但它对我没有帮助。

Answer 1

您可以calculate difference然后convert to natural language。并尝试下次在StackOverflow上使用搜索字段;）

Answer 2

这是我回过头来写的一个函数：

function relative_date($timestamp) {
    // calculate time difference
    $timediff = time() - $timestamp;
    switch($timediff) {
        // less than a minute, show seconds
        case $timediff <= 60:
            $seconds = $timediff;
            $str = $timediff . ($timediff == 1 ? " second ago" : " seconds ago");
            break;
        // less than a hour, show minutes
        case $timediff <= 3600:
            $minutes = floor($timediff / 60);
            $str = $minutes . ($minutes == 1 ? " minute ago" : " minutes ago");
            break;
        // less than a day, show hours
        case $timediff <= 86400:
            $hours = floor($timediff / 3600);
            $str = $hours . ($hours == 1 ? " hour ago" : " hours ago");
            break;
        // less than a year, show days
        case $timediff <= (86400 * 365):
            $days = floor($timediff / 86400);
            $str = $days . ($days == 1 ? " day ago" : " days ago");
            break;
        // over a year, just show years
        default:
            $years = floor($timediff / (86400 * 365));
            $str = $years . ($years == 1 ? " year ago" : " years ago");
    }
    return $str;
}
