Question

是否有公开的PHP公开的类/函数需要时间戳，并返回自那时以来的天数，月数，年数等等？基本上我想要生成与本网站上的每个条目（以及其他网站的挖掘和加载）一起呈现的自发布时间的相同功能。

Answer 1

这是一个wordpress插件，但你可以提取相关的PHP代码没问题：Fuzzy date-time

Answer 2

这是我写的一个Zend Framework ViewHelper，你可以很容易地修改它以不使用ZF特定的代码：

{
    /**

    private static $_time_formats = array(
        array(60, 'just now'),
        array(90, '1 minute'),                  // 60*1.5
        array(3600, 'minutes', 60),             // 60*60, 60

我不确定是否会有课程，但我在Google上找到了几种方法来实现您的目标：

也许其中一个适合或需要，或者你可以很容易地适应它。

Answer 4

谷歌兄弟知道答案：

之前有人问过：

How to calculate the difference between two dates using PHP?

这是我见过的最好的版本（人类可读格式）：

http://www.if-not-true-then-false.com/2010/php-calculate-real-differences-between-two-dates-or-timestamps/

PHP 5+现已内置：

http://php.net/manual/en/datetime.diff.php

我个人正在寻找计算天数（十进制），以便我可以将其分为几年等等。

function daysDifference($d1,$d2)
    {
    $ts2    =   strtotime($d1);
    $ts1    =   strtotime($d2);
        $seconds    = abs($ts2 - $ts1); # difference will always be positive
    $days = $seconds/60/60/24;
    return $days;
    }

Answer 5

此函数返回一个数字数组。您可以提取年，月，日，小时，分钟和秒。例如echo $ result [3]可以获得小时数和echo $ result [4]获得分钟数。（我借用了这段代码）。干杯！

function dateDiff($time1, $time2, $precision = 6)
    {
        // If not numeric then convert texts to unix timestamps
        if (!is_int($time1)) {
            $time1 = strtotime($time1);
        }
        if (!is_int($time2)) {
            $time2 = strtotime($time2);
        }

        // If time1 is bigger than time2
        // Then swap time1 and time2
        if ($time1 > $time2) {
            $ttime = $time1;
            $time1 = $time2;
            $time2 = $ttime;
        }

        // Set up intervals and diffs arrays
        $intervals = array('year', 'month', 'day', 'hour', 'minute', 'second');
        $diffs     = array();

        // Loop thru all intervals
        foreach ($intervals as $interval) {
            // Set default diff to 0
            $diffs[$interval] = 0;
            // Create temp time from time1 and interval
            $ttime = strtotime("+1 " . $interval, $time1);
            // Loop until temp time is smaller than time2
            while ($time2 >= $ttime) {
                $time1 = $ttime;
                $diffs[$interval]++;
                // Create new temp time from time1 and interval
                $ttime = strtotime("+1 " . $interval, $time1);
            }
        }

        $count = 0;
        $times = array();
        // Loop thru all diffs
        foreach ($diffs as $interval => $value) {
            // Break if we have needed precission
            if ($count >= $precision) {
                break;
            }
            // Add value and interval
            // if value is bigger than 0
            if ($value >= 0) {
                // Add s if value is not 1
                if ($value != 1) {
                    $interval .= "s";
                }
                // Add value and interval to times array
                $times[] = $value; // . " " . $interval;
                $count++;
            }
        }

        // Return string with times
        //return implode(", ", $times);
        return $times;
    }
