Question

例如，当您提交帖子时，可能会说“提前1秒”。如果它是2周大，它会说。 SO和Reddit是否编写了这些或者是否有一个PHP / SQL函数将日期转换为更易读的相关格式？

Answer 1

我强烈建议查看John Resig漂亮的日期库：

http://ejohn.org/blog/javascript-pretty-date/

如该博客文章所示，您可以执行以下操作：

prettyDate("2008-01-28T20:24:17Z") // => "2 hours ago"
prettyDate("2008-01-27T22:24:17Z") // => "Yesterday"
prettyDate("2008-01-26T22:24:17Z") // => "2 days ago"
prettyDate("2008-01-14T22:24:17Z") // => "2 weeks ago"
prettyDate("2007-12-15T22:24:17Z") // => undefined

Answer 2

它们被称为模糊日期/时间，JavaScript和PHP有很多库。

Answer 3

有很多方法可以做到这一点，但是如果你想使用php，那么这个函数将以一种很好的方式输出它只需将一个unix时间戳放在

中

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
    (
    " Years"   => 29030400, // seconds in a year   (12 months)
    " Months"  => 2419200,  // seconds in a month  (4 weeks)
    " Weeks"   => 604800,   // seconds in a week   (7 days)
    " Days"    => 86400,    // seconds in a day    (24 hours)
    " Hours"   => 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 > $to) ? (" from now") : (" "));
    foreach($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(""));
    if($output =='go' || $output ==' ago'){$output = 'A few secs ago';}
    return 'Posted '.str_ireplace('1 Days','1 Day',trim($output,', ')).' ago';
}

StackOverflow / Reddit的日期系统是否有库或已知函数？
