显示“时间之前”而不是PHP Codeigniter中的datetime [英] Display "time ago" instead of datetime in PHP Codeigniter

问题描述

我想显示一个类似twitter和FB的时间格式（发布于3小时前，发表于2分钟前，等等...）

I would like to display a time format like twitter and FB (Posted 3 hours ago, Posted 2 minutes ago and so on...)

尝试这段代码没有成功：

I've tried this piece of code without success :

function format_interval($timestamp, $granularity = 2) {
  $units = array('1 year|@count years' => 31536000, '1 week|@count weeks' => 604800, '1 day|@count days' => 86400, '1 hour|@count hours' => 3600, '1 min|@count min' => 60, '1 sec|@count sec' => 1);
  $output = '';
  foreach ($units as $key => $value) {
    $key = explode('|', $key);
    if ($timestamp >= $value) {
      $floor = floor($timestamp / $value);
      $output .= ($output ? ' ' : '') . ($floor == 1 ? $key[0] : str_replace('@count', $floor, $key[1]));
      $timestamp %= $value;
      $granularity--;
    }

    if ($granularity == 0) {
      break;
    }
}

我用这个函数回调到另一个函数， ：$ this-> format_interval（）;并将其传递给我的视图

I use this function with a callback into another function like : $this->format_interval(); and pass it to my View

我当前的格式日期是： 2012-07-26 09：31：pm 并已存储在我的数据库

My current format date is : 2012-07-26 09:31:pm and already stored in my DB

任何帮助将非常感激！

推荐答案

日期助手 timespan（）方法只是这样做：

此功能最常用的目的是显示从某个时间点到

The most common purpose for this function is to show how much time has elapsed from some point in time in the past to now.

给定一个时间戳，它将显示这种格式经过了多少时间：

Given a timestamp, it will show how much time has elapsed in this format:

1年，10个月，2周，5天，10小时，16分钟

1 Year, 10 Months, 2 Weeks, 5 Days, 10 Hours, 16 Minutes

所以，在你的例子中，你所需要做的就是将你的日期转换成时间戳，并执行如下操作：

So, in your example, all you need to do is convert your date to a timestamp and do something like this:

$post_date = '13436714242';
$now = time();

// will echo "2 hours ago" (at the time of this post)
echo timespan($post_date, $now) . ' ago';
