Question

是否有适用于UNIX时间戳差异的漂亮的漂亮打印库。社交网站上看到的东西，比如“x分钟前”，“x小时前”，“x天前”等等。我知道自己写作并不难写，但为什么重新发明轮子呢？

Answer 1

试

<?php
function rel_time($from, $to = null)
 {
  $to = (($to === null) ? (time()) : ($to));
  $to = ((is_int($to)) ? ($to) : (strtotime($to)));
  $from = ((is_int($from)) ? ($from) : (strtotime($from)));

  $units = array
  (
   "year"   => 29030400, // seconds in a year   (12 months)
   "month"  => 2419200,  // seconds in a month  (4 weeks)
   "week"   => 604800,   // seconds in a week   (7 days)
   "day"    => 86400,    // seconds in a day    (24 hours)
   "hour"   => 3600,     // seconds in an hour  (60 minutes)
   "minute" => 60,       // seconds in a minute (60 seconds)
   "second" => 1         // 1 second
  );

  $diff = abs($from - $to);
  $suffix = (($from > $to) ? ("from now") : ("ago"));

  foreach($units as $unit => $mult)
   if($diff >= $mult)
   {
    $and = (($mult != 1) ? ("") : ("and "));
    $output .= ", ".$and.intval($diff / $mult)." ".$unit.((intval($diff / $mult) == 1) ? ("") : ("s"));
    $diff -= intval($diff / $mult) * $mult;
   }
  $output .= " ".$suffix;
  $output = substr($output, strlen(", "));

  return $output;
 }
?>

我不知道是否有用于此的PHP库，但Jeff（创建此网站的人）很久以前就问过这个问题。有关详细信息，请参阅this question。我相信你可以从中获得很多灵感。杰夫甚至用the code they use on StackOverflow itself回答了这个问题。

我认为自己写这篇文章并不难，所以为什么不花5分钟写一下而不是半小时寻找一个图书馆呢？

从PHP 5.3起，PHP内置了一个类：

DateInterval

使用format()方法获取您想要的输出，但您需要决定我认为必要的单位。

Answer 4

defined('SECOND') ? NULL : define('SECOND', 1);
defined('MINUTE') ? NULL : define('MINUTE', 60 * SECOND);
defined('HOUR') ? NULL : define('HOUR', 60 * MINUTE);
defined('DAY') ? NULL : define('DAY', 24 * HOUR);
defined('MONTH') ? NULL : define('MONTH', 30 * DAY);
defined('YEAR') ? NULL : define('YEAR', 12 * MONTH);

class Time{
    public $td;

    public function set_td($timestamp){
        $this->td = time() - $timestamp;
    }

    public function string_time($timestamp){

        $this->set_td($timestamp);


        if ($this->td < 0){
            return "not yet";
        }
        if ($this->td < 1 * MINUTE){
             return $this->td <= 1 ? "just now" : $this->td." seconds ago";
        }
        if ($this->td < 2 * MINUTE){
          return "a minute ago";
        }
        if ($this->td < 45 * MINUTE){
            return floor($this->td / MINUTE)." minutes ago";
        }
        if ($this->td < 90 * MINUTE){
            return "an hour ago";
        }
        if ($this->td < 24 * HOUR){
            return floor($this->td / HOUR)." hours ago";
        }
        if ($this->td < 48 * HOUR){
            return "yesterday";
        }
        if ($this->td < 30 * DAY){
             return floor($this->td / DAY)." days ago";
        }
        if ($this->td < 12 * MONTH){
            $months = floor($this->td / MONTH);
            return $months <= 1 ? "one month ago" : $months." months ago";
        }else{
            $years = floor($this->td / YEAR);
            return $years <= 1 ? "one year ago" : $years." years ago";
        }
     }
 }

$time = new Time();

只需将时间戳记放入新对象并以秒为单位接收时差。

$string = $time->string_time($timestamp);

漂亮的打印库，用于PHP中的时差
