我有以下格式的时间戳：2013-10-19 18:47:30

我正在使用它来转换为相对（x 分钟、小时、天前）时间，但它不会为最近的用户返回任何内容，我假设因为我的系统时间是 GMT -3 小时，所以它将它解释为未来的时间. 如果是这种情况，我如何在结果中考虑用户 GMT 偏移量？

$time = strtotime('2013-04-28 17:25:43');

echo 'event happened '.humanTiming($time).' ago';

function humanTiming ($time)
{

    $time = time() - $time; // to get the time since that moment

    $tokens = array (
        31536000 => 'year',
        2592000 => 'month',
        604800 => 'week',
        86400 => 'day',
        3600 => 'hour',
        60 => 'minute',
        1 => 'second'
    );

    foreach ($tokens as $unit => $text) {
        if ($time < $unit) continue;
        $numberOfUnits = floor($time / $unit);
        return $numberOfUnits.' '.$text.(($numberOfUnits>1)?'s':'');
    }

}

$eventTimeString = '2013-04-28 17:25:43';
$timezone = new DateTimeZone("Etc/GMT+3"); // Same as GMT-3, here you should use the users's timezone
$eventTime = new DateTime($eventTimeString , $timezone);

$diff = $eventTime->diff(new DateTime()); // Compare with

该$diff变量现在具有秒数、月数、天数等​​，因为$eventTime

object(DateInterval)#4 (15) {
  ["y"]=>
  int(0)
  ["m"]=>
  int(7)
  ["d"]=>
  int(18)
  ["h"]=>
  int(17)
  ["i"]=>
  int(35)
  ["s"]=>
  int(38)
  ["weekday"]=>
  int(0)
  ["weekday_behavior"]=>
  int(0)
  ["first_last_day_of"]=>
  int(0)
  ["invert"]=>
  int(0)
  ["days"]=>
  int(232)
  ["special_type"]=>
  int(0)
  ["special_amount"]=>
  int(0)
  ["have_weekday_relative"]=>
  int(0)
  ["have_special_relative"]=>
  int(0)
}

这是您的方法的重写，它将更加可靠/准确：

function humanTiming($time){
    $timezone=new DateTimeZone("Australia/Melbourne"); // declare whatever your user's timezone is
    $time=new DateTime($time,$timezone);  // input your datetime
    $now=new DateTime("now",$timezone); // get current datetime
    if($time>$now){
        return "event hasn't happened yet";
    }elseif($time==$now){
        return "event is happening";
    }
    $diff=(array)$time->diff($now);  // get time between now and $time, cast as array

    $labels=array("y"=>"year","m"=>"month","d"=>"day","h"=>"hour","i"=>"minute","s"=>"second");
    $readable="";       // declare as empty string
    // filter the $diff array to only  the desired elements and loop
    foreach(array_intersect_key($diff,$labels) as $k=>$v){
        if($v>0){  // only add non-zero values to $readable
            $readable.=($readable!=""?", ":"")."$v {$labels[$k]}".($v>1?"s":"");
            //  use comma-space as glue | show value | show unit | pluralize when necessary
        }
    }
    return "event happened $readable ago";
}

echo humanTiming('2013-04-28 17:25:43');

// event happened 3 years, 10 months, 23 days, 8 hours, 33 minutes, 59 seconds ago
