PHP How to Find the Time Elapsed Since a Date Time

PHP How to find the time elapsed since a date time?

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:

$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<1)? 1 : $time;
    $tokens = array (
        31536000 => 'year',
        2592000 => 'month',
        604800 => 'week',
        86400 => 'day',
        3600 => 'hour',
        60 => 'minute',
        1 => 'second'
    );

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

}

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

The result would look like

event happened 4 days ago

or

event happened 1 minute ago

cheers

How to find the time elapsed since a date time and what time is it like notification facebook?

I have updated your function. Please add required validation

function time_elapsed_string($datetime, $full = false) {
        $now = new DateTime();

        $ago = new DateTime($datetime);
        $diff = $now->diff($ago);

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

        $string = array(
            'y' => 'year',
            'm' => 'month',
            'w' => 'week',
            'd' => 'day',
            'h' => 'hour',
            'i' => 'minute',
            's' => 'second',
        );
        foreach ($string as $k => &$v) {
            if ($diff->$k) {
                $v = $diff->$k ;//. ' ' . $v . ($diff->$k > 1 ? 's' : '');

            } else {
                unset($string[$k]);
            }
        }

        if (!$full) $string = array_slice($string, 0, 1);

     if(!empty($string['y']) || !empty($string['m']) || !empty($string['w']) )
        {
            echo showdate($datetime,'w')."<br>";
        } 
     elseif(!empty($string['d']) )
        {
            if($string['d'] > 1)
            {
              echo showdate($datetime,'w')."<br>";
            }
            else
            {
               echo showdate($datetime,'d')."<br>";
            }
        }
     elseif(!empty($string['h']) )
        {
         echo implode(', ', $string) . 'h ago';//"<br>";
        }
        elseif(!empty($string['i'])  )
        {
          echo implode(', ', $string) . 'mints ago';//"<br>";
        }
        elseif( !empty($string['s']))
       {
         echo 'just now';//"<br>";
        }
     // return $string ? implode(', ', $string) . ' ago' : 'just now';
    }


function showdate($dt,$type)
{
    $mydt  = new DateTime($dt);
    if($type == 'd')
    {
        $str = 'Yesterday at '.$mydt->format('H:i:s ');
    }
    elseif($type == 'h')
    {
        //$str = 'Yesterday at '.$mydt->format('H:i:s ');
    }
    else
    {
        $str = $mydt->format('M d');
        $str .= ' at '.$mydt->format('H:i:s ');
    }

    return $str;
}
    $created_date = '2016-06-29 04:50:00';

    echo time_elapsed_string($created_date);

PHP find the time elapsed since a date time inside a foreach loop

Thanks to @Clément Malet to point me in the right direction, DateTime::diff helped me to get the solution:

<?php foreach($comments as $comment): ?>
<?php
// foreach items
$data = $comment['cacheDate']; // this store a unix value like 1404992204999
// foreach items
<!--  html code -->
<div class="message">
<p class="data"><strong>Published: </strong>
<?php 
    $date1 = $data;
    $date2 = time();
    $subTime = $date1 - $date2;
    $y = ($subTime/(60*60*24*365));
    $d = ($subTime/(60*60*24))%365;
    $h = ($subTime/(60*60))%24;
    $m = ($subTime/60)%60;

    echo $h." hour and " . $m." minutes"; // no need for years and days
?>      
<strong>ago </strong>
</div>
<?php endforeach; ?>
<?php else: ?>
<h2>There are no comments yet</h2>
<?php endif; ?>

And the final output is like: Published: 10 hour and 25 minutes ago

Check if time elapsed since date is more than X days

You can use DateTime class for this. Example:

$dt = "2011-03-19 10:05:44";
$date = new DateTime($dt);
$now = new DateTime();
$diff = $now->diff($date);
if($diff->days > 90) {
    echo 'its greater than 90 days';
}

How do I extract the number of seconds elapsed from a specific date?

See my answer here:
Calculate number of hours between 2 dates in PHP

Date1 would be the date, when the question was posted and Date2 would be the current date. This version of comparing respects leap-seconds and leap-years and timezones, so it's more detailed than just comparing two unix-timestamps.

How to get time difference in minutes in PHP

Subtract the past most one from the future most one and divide by 60.

Times are done in Unix format so they're just a big number showing the number of seconds from January 1, 1970, 00:00:00 GMT
