You'll have to take each individual piece of your timestamp, and convert it into Unix time. For example for the timestamp, 2009-09-12 20:57:19.

(((2008-1970)*365)+(8*30)+12)*24+20 would give you a ROUGH estimate of the hours since January 1st, 1970.

Take that number, multiply by 60 and add 57 to get the minutes.

Take that, multiply by 60 and add 19.

That would convert it very roughly and inaccurately however.

Is there any reason you can't just take the normal Unix time to begin with?

I'm aware that there are several answers here, but this is what I came up with. This only handles MySQL DATETIME values as per the original question I was responding to. The array $a needs some work. I welcome comments on how to improve. Call as:

 $csqltime = date('Y-m-d H:i:s');

 // Current time as Unix timestamp
 $ctime = strtotime($csqltime); 

 // Elapsed time
 $etime = $ctime - $ptime;

 // If no elapsed time, return 0
 if ($etime &lt; 1){
 return '0 seconds';
 }

 $a = array( 365 * 24 * 60 * 60 =&gt; 'year',
 30 * 24 * 60 * 60 =&gt; 'month',
 24 * 60 * 60 =&gt; 'day',
 60 * 60 =&gt; 'hour',
 60 =&gt; 'minute',
 1 =&gt; 'second'
 );

 $a_plural = array( 'year' =&gt; 'years',
 'month' =&gt; 'months',
 'day' =&gt; 'days',
 'hour' =&gt; 'hours',
 'minute' =&gt; 'minutes',
 'second' =&gt; 'seconds'
 );

 foreach ($a as $secs =&gt; $str){
 // Divide elapsed time by seconds
 $d = $etime / $secs;
 if ($d &gt;= 1){
 // Round to the next lowest integer 
 $r = floor($d);
 // Calculate time to remove from elapsed time
 $rtime = $r * $secs;
 // Recalculate and store elapsed time for next loop
 if(($etime - $rtime) &lt; 0){
 $etime -= ($r - 1) * $secs;

Many solutions here did not account for rounding. For example:

Event happened at 3pm two days ago. If you are checking at 2pm, it will show one day ago. If you are checking at 4pm it will show two days ago.

If you are working with unix time, this helps:

<pre><code>// how long since event has passed in seconds
$secs = time() - $time_ago;

// how many seconds in a day
$sec_per_day = 60*60*24;

// days elapsed
$days_elapsed = floor($secs / $sec_per_day);

// how many seconds passed today
$today_seconds = date('G')*3600 + date('i') * 60 + date('s');

// how many seconds passed in the final day calculation
$remain_seconds = $secs % $sec_per_day;

if($today_seconds &lt; $remain_seconds)
{
 $days_elapsed++;
}

echo 'The event was '.$days_ago.' days ago.';
</code></pre>

It is not perfect if you are worried about leap seconds and daylight savings time.

I wanted to have dutch version that supported singles and plurals. Just adding an 's' at the end would not suffice, we use completely different words so I rewrote the top answer of this post.
This will result in:
<code>2 jaren 1 maand 2 weken 1 dag 1 minuten 2 seconden</code>
or
<code>1 jaar 2 maanden 1 week 2 dagen 1 minuut 1 seconde</code>
<pre><code> public function getTimeAgo($full = false){

 $now = new \DateTime;
 $ago = new \DateTime($this-&gt;datetime());
 $diff = $now-&gt;diff($ago);

 $diff-&gt;w = floor($diff-&gt;d / 7);
 $diff-&gt;d -= $diff-&gt;w * 7;

 $string = array(
 'y' =&gt; 'jaren',
 'm' =&gt; 'maanden',
 'w' =&gt; 'weken',
 'd' =&gt; 'dagen',
 'h' =&gt; 'uren',
 'i' =&gt; 'minuten',
 's' =&gt; 'seconden',
 );
 $singleString = array(
 'y' =&gt; 'jaar',
 'm' =&gt; 'maand',
 'w' =&gt; 'week',
 'd' =&gt; 'dag',
 'h' =&gt; 'uur',
 'i' =&gt; 'minuut',
 's' =&gt; 'seconde',
 );
 // M.O. 2022-02-11 I rewrote this function to support dutch singles and plurals. Added some docs for next programmer to break his brain :)
 // For each possible notation, if corresponding value of current key is true (&gt;1) otherwise remove its key/value from array
 // If the value from current key is 1, use value from $singleString array. Otherwise use value from $string array
 foreach ($string as $k =&gt; &amp;$v) {
 if ($diff-&gt;$k) {
 if($diff-&gt;$k == 1){
 $v = $diff-&gt;$k . ' ' . $singleString[$k];
 } else {
 $v = $diff-&gt;$k . ' ' . $v;
 }
 } else {
 if($diff-&gt;$k == 1){
 unset($singleString[$k]);
 } else {
 unset($string[$k]);
 }
 }
 }

 // If $full = true, print all values.
 // Values have already been filtered with foreach removing keys that contain a 0 as value
 if (!$full) $string = array_slice($string, 0, 1);
 return $string ? implode(', ', $string) . '' : 'zojuist';
}

You should probably test it first because I am not that good of a programmer :)

I am trying to convert a timestamp of the format <code>2009-09-12 20:57:19</code> and turn it into something like <code>3 minutes ago</code> with PHP.

I found a useful script to do this, but I think it's looking for a different format to be used as the time variable. The script I'm wanting to modify to work with this format is:

<pre><code>function _ago($tm,$rcs = 0) {
 $cur_tm = time(); 
 $dif = $cur_tm-$tm;
 $pds = array('second','minute','hour','day','week','month','year','decade');
 $lngh = array(1,60,3600,86400,604800,2630880,31570560,315705600);

 for($v = sizeof($lngh)-1; ($v &gt;= 0)&amp;&amp;(($no = $dif/$lngh[$v])&lt;=1); $v--); if($v &lt; 0) $v = 0; $_tm = $cur_tm-($dif%$lngh[$v]);
 $no = floor($no);
 if($no &lt;&gt; 1)
 $pds[$v] .='s';
 $x = sprintf("%d %s ",$no,$pds[$v]);
 if(($rcs == 1)&amp;&amp;($v &gt;= 1)&amp;&amp;(($cur_tm-$_tm) &gt; 0))
 $x .= time_ago($_tm);
 return $x;
 }
</code></pre>

I think on those first few lines the script is trying to do something that looks like this (different date format math):

<pre><code>$dif = 1252809479 - 2009-09-12 20:57:19;
</code></pre>

How would I go about converting my timestamp into that (unix?) format?

我正在尝试转换2009-09-12 20:57:19格式的时间戳，并使用PHP将其转换为类似3 minutes ago的格式。我找到了一个有用的脚本来做这件事，但我认为它正在寻找一种不同的格式来用作时间变量。我想要修改的脚本是：function _ago($tm,$rcs = 0) {    $cur_tm = tim...
