blocks|key|1024459|text|为了找出经过的时间，我通常使用time()而不是date()和格式化的时间戳。然后得到后一个值和前一个值之间的差异，并相应地格式化。不同的是，time()不是date()的替代品，但它在计算运行时间时完全有帮助。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1024460|示例：|1024461|time()的值看起来类似于1274467343每秒递增一次。因此，您可以使用值为1274467343的$erlierTime和值为1274467500的$latterTime，然后只需执行$latterTime+-+$erlierTime即可获得以秒为单位的运行时间。|1024462|entityMap^0|F|6|O|6|1Z|6|27|6|0|0|0|6|E|A|15|A|1G|B|1U|A|25|B|2N|P|0^^$0|@$1|2|3|4|5|6|7|L|8|@$9|M|A|N|B|C]|$9|O|A|P|B|C]|$9|Q|A|R|B|C]|$9|S|A|T|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|U|8|@]|D|@]|E|$]]|$1|H|3|I|5|6|7|V|8|@$9|W|A|X|B|C]|$9|Y|A|Z|B|C]|$9|10|A|11|B|C]|$9|12|A|13|B|C]|$9|14|A|15|B|C]|$9|16|A|17|B|C]|$9|18|A|19|B|C]]|D|@]|E|$]]|$1|J|3|-4|5|6|7|1A|8|@]|D|@]|E|$]]]|K|$]]

To find out time elapsed i usually use <code>time()</code> instead of <code>date()</code> and formatted time stamps.
Then get the difference between the latter value and the earlier value and format accordingly. <code>time()</code> is differently not a replacement for <code>date()</code> but it totally helps when calculating elapsed time.

example:

The value of <code>time()</code> looks something like this <code>1274467343</code> increments every second. So you could have <code>$erlierTime</code> with value <code>1274467343</code> and <code>$latterTime</code> with value <code>1274467500</code>, then just do <code>$latterTime - $erlierTime</code> to get time elapsed in seconds.

Convert [saved_date] to timestamp. Get current timestamp.

current timestamp - [saved_date] timestamp.

Then you can format it with date();

You can normally convert most date formats to timestamps with the strtotime() function.

blocks|key|1024596|text|适用于任何版本的PHP的一种选择是执行已经建议的操作，如下所示：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1024597|$eventTime+=+'2010-04-28+17:25:43';

One option that'll work with any version of PHP is to do what's already been suggested, which is something like this:

<pre><code>$eventTime = '2010-04-28 17:25:43';
$age = time() - strtotime($eventTime);
</code></pre>

That will give you the age in seconds. From there, you can display it however you wish.

One problem with this approach, however, is that it won't take into account time shifts causes by DST. If that's not a concern, then go for it. Otherwise, you'll probably want to use the <a href="http://us2.php.net/manual/en/function.date-diff.php" rel="nofollow noreferrer">diff() method in the DateTime class</a>. Unfortunately, this is only an option if you're on at least PHP 5.3.

I think I have a function which should do what you want:

<pre><code>function time2string($timeline) {
 $periods = array('day' =&gt; 86400, 'hour' =&gt; 3600, 'minute' =&gt; 60, 'second' =&gt; 1);

 foreach($periods AS $name =&gt; $seconds){
 $num = floor($timeline / $seconds);
 $timeline -= ($num * $seconds);
 $ret .= $num.' '.$name.(($num &gt; 1) ? 's' : '').' ';
 }

 return trim($ret);
}
</code></pre>

Simply apply it to the difference between <code>time()</code> and <code>strtotime('2010-04-28 17:25:43')</code> as so:

<pre><code>print time2string(time()-strtotime('2010-04-28 17:25:43')).' ago';

Most of the answers seem focused around converting the date from a string to time. It seems you're mostly thinking about getting the date into the '5 days ago' format, etc.. right?

This is how I'd go about doing that:

<pre><code>$time = strtotime('2010-04-28 17:25:43');

echo 'event happened '.humanTiming($time).' ago';

function humanTiming ($time)
{

 $time = time() - $time; // to get the time since that moment
 $time = ($time&lt;1)? 1 : $time;
 $tokens = array (
 31536000 =&gt; 'year',
 2592000 =&gt; 'month',
 604800 =&gt; 'week',
 86400 =&gt; 'day',
 3600 =&gt; 'hour',
 60 =&gt; 'minute',
 1 =&gt; 'second'
 );

 foreach ($tokens as $unit =&gt; $text) {
 if ($time &lt; $unit) continue;
 $numberOfUnits = floor($time / $unit);
 return $numberOfUnits.' '.$text.(($numberOfUnits&gt;1)?'s':'');
 }

}
</code></pre>

I haven't tested that, but it should work. 

The result would look like

<pre><code>event happened 4 days ago
</code></pre>

or 

<pre><code>event happened 1 minute ago
</code></pre>

cheers

To improve upon @arnorhs answer I've added in the ability to have a more precise result so if you wanted years, months, days &amp; hours for instance since the user joined.

I've added a new parameter to allow you to specify the number of points of precision you wish to have returned.

<pre><code>function get_friendly_time_ago($distant_timestamp, $max_units = 3) {
 $i = 0;
 $time = time() - $distant_timestamp; // to get the time since that moment
 $tokens = [
 31536000 =&gt; 'year',
 2592000 =&gt; 'month',
 604800 =&gt; 'week',
 86400 =&gt; 'day',
 3600 =&gt; 'hour',
 60 =&gt; 'minute',
 1 =&gt; 'second'
 ];

 $responses = [];
 while ($i &lt; $max_units &amp;&amp; $time &gt; 0) {
 foreach ($tokens as $unit =&gt; $text) {
 if ($time &lt; $unit) {
 continue;
 }
 $i++;
 $numberOfUnits = floor($time / $unit);

 $responses[] = $numberOfUnits . ' ' . $text . (($numberOfUnits &gt; 1) ? 's' : '');
 $time -= ($unit * $numberOfUnits);
 break;
 }
 }

 if (!empty($responses)) {
 return implode(', ', $responses) . ' ago';
 }

 return 'Just now';
}

Improvisation to the function "humanTiming" by arnorhs. It would calculate a "fully stretched" translation of time string to human readable text version. For example to say it like "1 week 2 days 1 hour 28 minutes 14 seconds"

<pre><code>function humantime ($oldtime, $newtime = null, $returnarray = false) {
 if(!$newtime) $newtime = time();
 $time = $newtime - $oldtime; // to get the time since that moment
 $tokens = array (
 31536000 =&gt; 'year',
 2592000 =&gt; 'month',
 604800 =&gt; 'week',
 86400 =&gt; 'day',
 3600 =&gt; 'hour',
 60 =&gt; 'minute',
 1 =&gt; 'second'
 );
 $htarray = array();
 foreach ($tokens as $unit =&gt; $text) {
 if ($time &lt; $unit) continue;
 $numberOfUnits = floor($time / $unit);
 $htarray[$text] = $numberOfUnits.' '.$text.(($numberOfUnits&gt;1)?'s':'');
 $time = $time - ( $unit * $numberOfUnits );
 }
 if($returnarray) return $htarray;

I just started using the latter, does the trick, but no stackoverflow-style fallback on exact date when the date in question is too far away, nor is there support for future dates - and the API is a little funky, but at least it works seemingly flawlessly and is maintained...
