函数来格式化时间差异 [英] function that formats the time difference

问题描述

我试图创建一个将日期与当前时间进行比较的函数，并返回一个格式良好的字符串。

我已经用匆忙的方式编写了一些代码并且它可以工作，但我试图找到这是一种更有效的方式。这是我的代码：

 函数_formatDate（$ dateStr）
 {
 $ timestr =; 
 $ t = time（） -  strtotime（$ dateStr）; 
 if（$ t <60）{
 $ timestr ={$ t} seconds ago; 
} 
 elseif（$ t <120）{
 $ timestr =大约一分钟前; 
} 
 elseif（$ t <3600）{
 $ minute = floor（$ t / 60）; 
 $ timestr ={$ minute} minutes ago; 
} 
 elseif（$ t <7200）{
 $ timestr =约一小时前; 
} 
 elseif（$ t <86400）{
 $ hour = floor（$ t / 3600）; 
 $ timestr ={$ hour} hours ago; 
} 
 elseif（$ t <172800）{
 $ timestr =一天前; 
} 
 elseif（$ t <2592000）{
 $ day = floor（$ t / 86400）; 
 $ timestr ={$ day} days ago; 
} 
 elseif（$ t <5184000）{
 $ timestr =大约一个月前; 
} 
 else {
 $ month = floor（$ t / 2592000）; 
 $ timestr ={$ month} months ago; 
} 
返回$ timestr; 
} 
  

解决方案

从来没有失败，只要把Unix时间戳放进去，如果你在函数中使用第二个参数，可以是to条件。 > echo timeDiffrence（'1300392875'）;

函数timeDiffrence（$ from，$ to = null）{
$ to =（（$ to === null）？（time（））：（$ to））; $（$ to $）=（（is_int（$ to））？（$ to）:( strtotime（$ to）））;
$ =（（is_int（$ from））？（$ from）：（strtotime（$ from）））;
$ units = array
（
y=> 29030400，//一年中的秒数（12个月）
month=> 2419200，//秒在一个月内（4周）
w=> 604800，//一周中的秒数（7天）
d=> 86400，//一天中的秒数）
h=> 3600，//一小时内的秒数（60分钟）
m=> 60，//一分钟内的秒数（60秒）
s=> 1 // 1秒
）;
$ diff = abs（$ from - $ to）;
$ suffix =（（$ from> $ to）？（from now）：（ago））;
foreach（$ units为$ unit => $ mult）
if（$ diff> = $ mult）
{
// $ and =（（$ mult！ = 1）？（）：（and））; $（）$（$）$（$）$（$）$（$）$（$）$（$）$ ））;
$ diff - = intval（$ diff / $ mult）* $ mult;
}
$ output。=。$ suffix;
$ output = substr（$ output，strlen（））;
if（$ output =='go'|| $ output =='ago'）{$ output ='几秒前';}
return $ output;
}

I am trying to create a function that compares a date with the current time, and returns a nicely formatted string.
I have written some code in haste and it works, but I am trying to find a more efficient way of doing it. Here is my code:

    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;
}

解决方案

Some code I use and it's never failed, just put the Unix timestamp in, if you use a second argument in the function that can be the "to" condition

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;
}
