Question

我正在尝试创建一个将日期与当前时间进行比较的函数，并返回格式正确的字符串我已经在仓促中编写了一些代码并且它可以工作，但我正在尝试找到一种更有效的方法。这是我的代码：

    function _formatDate($dateStr)
    {
    $timestr = "";
    $t= time() - strtotime($dateStr);
    if($t < 60) {
        $timestr = "{$t} seconds ago";
    }
    elseif ($t <120) {
        $timestr = "about a minute ago";
    }
    elseif ($t < 3600) {
        $minute = floor($t/60);
        $timestr = "{$minute} minutes ago";
    }
    elseif ($t < 7200) {
        $timestr = " about an hour ago";
    }
    elseif ($t < 86400) {
        $hour = floor($t/3600);
        $timestr = "{$hour} hours ago";
    }
    elseif ($t < 172800) {
        $timestr = "a day ago";
    }
    elseif ($t < 2592000) {
        $day = floor($t/86400);
        $timestr = "{$day} days ago";
    }
    elseif ($t < 5184000){
        $timestr = "about a month ago";
    }
    else {
        $month = floor($t/2592000);
        $timestr = "{$month} months ago";
    }
    return $timestr;
}

我使用的一些代码并且它永远不会失败，只是将Unix时间戳放入，如果你在函数中使用第二个参数可以是“to”条件

echo timeDiffrence('1300392875');

function timeDiffrence($from, $to = null){
    $to = (($to === null) ? (time()) : ($to));
    $to = ((is_int($to)) ? ($to) : (strtotime($to)));
    $from = ((is_int($from)) ? ($from) : (strtotime($from)));
    $units = array
    (
    "y"   => 29030400, // seconds in a year   (12 months)
    "month"  => 2419200,  // seconds in a month  (4 weeks)
    "w"   => 604800,   // seconds in a week   (7 days)
    "d"    => 86400,    // seconds in a day    (24 hours)
    "h"   => 3600,     // seconds in an hour  (60 minutes)
    "m" => 60,       // seconds in a minute (60 seconds)
    "s" => 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) ? ("") : (""));
        $diff -= intval($diff / $mult) * $mult;
    }
    $output .= " ".$suffix;
    $output = substr($output, strlen(""));
    if($output =='go' || $output ==' ago'){$output = 'A few secs ago';}
    return $output;
}

我建议你在javascript中使用它。您可以使用TimeAgo插件进行jquery。关于这一点很酷的是它将在客户端实时更新而不需要任何页面刷新。这很简单易用，符合您的要求。
