如何以人类格式（时间前......等）但以多语言风格获得时差

Question

zend 中是否有任何视图助手或库，例如，我可以使用它来获取两个时间戳之间的差异，但会自动将 'y li a' 放在时间前面。例如，前一段时间的法国标准...

答案是否定的，但也许这会有所帮助：

    {
        if (null === $format) $format = '%y %m %d %h %i';

        if (self::$_locale == null) {

            $list   = array();

            try {

                    $locale = new Zend_Locale($default);
                }
            }

            self::$_locale = $locale;
            self::$_translations = Zend_Locale::getTranslationList('unit', $locale);
        }

        $table    = self::$_translations;

        /* uncomment to handle weeks
        if ($days >= 7) {
            $weeks = (int)($days / 7);

        if (strpos($format, '%y') !== false && $years > 0) {

        }

        if (strpos($format, '%m') !== false && $months > 0) {
            $diff[] = str_replace('{0}', $months, $table['month'][($months != 1 || !isset($table['month']['one']) ? 'other' : 'one')]);
        }

        }

        if (strpos($format, '%i') !== false && $minutes > 0) {
            $diff[] = str_replace('{0}', $minutes, $table['minute'][($minutes != 1 || !isset($table['minute']['one']) ? 'other' : 'one')]);
        }

        return implode(' ', $diff);
    }

    protected function isValidTimestamp($timestamp)
    {
        $ts = (int)$timestamp;
        $d  = date('Y-m-d H:i:s', $ts);

        return strtotime($d) === $ts;
    }
}

一旦注册，从你的角度这样称呼它：

<?php echo $this->timeDiff($object->pastTimestamp) ?> $this->_xlate('ago');

示例输出：

1 année 5 mois 15 jours 21 heures 56 minutes il ya
1 год 5 месяца 15 дня 22 часа 1 минута назад

请注意，助手不处理“之前”部分，在某些语言（法语）中，它位于差异之前，而在其他语言（英语）中，它位于末尾。您还需要在自己的翻译文件中定义此翻译字符串，ZF 没有针对它的翻译。理想情况下，该逻辑将内置到帮助程序中，但我没有这样做。

希望对您有所帮助。

Answer 2

时间戳是一个数字，您可以简单地从结束时间减去开始时间来获得差值。你可以这样做：

public function timeDiff($timestampFrom, $timestampTo) {

$timeDiff = new Zend_Date($timestampTo - $timestampFrom, Zend_Date::TIMESTAMP);

$output = "il y a ";

//Check the number of days:
if($timeDiff->getTimestamp > 60*60*24) $output .= $timeDiff->get(Zend_Date::DAY).' jours, ';
//Check the hours
if($timeDiff->getTimestamp > 60*60) $output .= $timeDiff->get(Zend_Date::HOUR).' heures, ';
//Check the minutes
if($timeDiff->getTimestamp > 60) $output .= $timeDiff->get(Zend_Date::MINUTE).' minutes et ';
//Check the seconds
$output .= $timeDiff->get(Zend_Date::SECOND)." secondes";

return $output;
}

Matthieu 的评论是对的，法语中没有“y li a”这样的词。您可能的意思是“il y a”。 ;)
