Question

所以，我有这个工作代码，它将MySQL日期转换为UNIX时间戳，并从当前日期（）中减去它，以显示“自X以来经过的时间”计时器。（从数据库中获取日期的部分缺失，因为它在另一个脚本中）

    <?php 
    function time_elapsed($secs){
        $bit = array(
            ' year'        => $secs / 31556926 % 12,
            ' week'        => $secs / 604800 % 52,
            ' day'        => $secs / 86400 % 7,
            ' hour'        => $secs / 3600 % 24,
            ' minute'    => $secs / 60 % 60,
            ' second'    => $secs % 60
            );
        foreach($bit as $k => $v){
            if($v > 1)$ret[] = $v . $k . 's';
            if($v == 1)$ret[] = $v . $k;
            }
        array_splice($ret, count($ret)-1, 0, 'and');
        $ret[] = 'ago.';

        return join(' ', $ret);
        }

    $nowtime = time() + 10; //add 10s to avoid error
    $oldtime = strtotime($mysqltime2);

    $time_elapsed = time_elapsed($nowtime-$oldtime)."\n";
    echo wordwrap($time_elapsed,35,"<br />\n"); //split long line
    ?>

如果脚本是在MySQL日期的同一时间执行的话，我设法修复了报告丢失数组的错误，或者添加10秒到当前时间戳。

我遇到的另一个问题是脚本显示“和X秒”，即使它没有分钟/小时/天/等。例如。 “和 X秒” “Y分钟和 X秒” “Z小时Y分钟和 X秒” “N天Z小时Y分钟和 X秒”

如果之前没有分钟/小时/等，我想在秒之前删除“和”。

有关如何解决此问题的任何提示？

Answer 1

我能想到的最简单的是

$time_elapsed = time_elapsed($nowtime-$oldtime))."\n";
if($nowtime-$oldtime < 61){
  $time_elapsed=str_replace('and ',' ',$time_elapsed);
}

Answer 2

您只能在需要时拼接：

if( count($ret) > 1 ) {
    array_splice($ret, count($ret)-1, 0, 'and');
}

Answer 3

不确定这是否有帮助，但为什么不在mysql中执行大部分日期数学？

以下是我在网站的评论部分列出帖子之前所做的事情，它输出＆＃34; 2小时前发布的帖子＆＃34;等

SQL：

UNIX_TIMESTAMP(NOW()) - UNIX_TIMESTAMP(made_on)  as madeon

PHP（将查询传递给此处）：

function seconds_to_textual_time_ago($seconds)
    {
    $hour = 60* 60;
    $day = 24 * $hour;
    $month = 30 * $day;
    $year = 365 * $day;

    switch(true) 
        {
        case ($seconds < 60) :
            $time_ago = "Less than 1 minute ago";
            break;

        case ($seconds >= 60 && $seconds < $hour):
            $minutes = floor($seconds /60);
            if ($minutes > 1) 
                $time_ago = "$minutes minutes ago";
            else
                $time_ago = "1 minute ago";
            break;



        case ($seconds >= $hour && $seconds < $day):
            $hours = floor($seconds /$hour);
            if ($hours > 1) 
                $time_ago = "$hours hours ago";
            else
                $time_ago = "1 hour ago";
            break;


        case ($seconds >= $day && $seconds < $month):
            $days = floor($seconds /$day);
            if ($days > 1) 
                $time_ago = "$days days ago";
            else
                $time_ago = "1 day ago";
            break;


        case ($seconds >= $month && $seconds < $year):
            $months = floor($seconds /$month);
            if ($months > 1) 
                $time_ago = "$months months ago";
            else
                $time_ago = "1 month ago";
            break;

        case ($seconds >= $year ):
            $years = floor($seconds /$year);
            if ($years > 1) 
                $time_ago = "$years years ago";
            else
                $time_ago = "1 year ago";
            break;


        default:
            break;
        }
    return $time_ago;
    }

PHP时间已过，删除＆＃34;和＆＃34;在秒之前
