Php 将时间戳转换为“X秒前”、“X分钟前”、“X小时前”等

如果php已经内置了功能，有人会这样做吗

谢谢，

此功能没有内置功能……但以下功能可以完成此功能

<?php
function nicetime($date)
{
    if(empty($date)) {
        return "No date provided";
    }

    $periods         = array("second", "minute", "hour", "day", "week", "month", "year", "decade");
    $lengths         = array("60","60","24","7","4.35","12","10");

    $now             = time();
    $unix_date         = strtotime($date);

       // check validity of date
    if(empty($unix_date)) {   
        return "Bad date";
    }

    // is it future date or past date
    if($now > $unix_date) {   
        $difference     = $now - $unix_date;
        $tense         = "ago";

    } else {
        $difference     = $unix_date - $now;
        $tense         = "from now";
    }

    for($j = 0; $difference >= $lengths[$j] && $j < count($lengths)-1; $j++) {
        $difference /= $lengths[$j];
    }

    $difference = round($difference);

    if($difference != 1) {
        $periods[$j].= "s";
    }

    return "$difference $periods[$j] {$tense}";
}

$date = "2009-03-04 17:45";
$result = nicetime($date); // 2 days ago

?>

只会在两天前回来

但是如果你想得到1秒前、10秒前的结果，你还需要在$date中加上秒数

$date = "2009-03-04 17:45:20";
$result = nicetime($date);

因此，当您添加一个新的db条目并立即刷新页面时，您将得到1秒前的结果，而不是本机生成的结果，但我对的回答可能对您有用。刚刚找到一个函数，该函数正是我所需要的，可能是as的副本

$date = "2009-03-04 17:45:20";
$result = nicetime($date);
