PHP How to find the time elapsed since a date time? [duplicate]

Answer 1

If you use the php Datetime class you could use:

function time_ago(Datetime $date) {
  $time_ago = '';

  $diff = $date->diff(new Datetime('now'));


  if (($t = $diff->format("%m")) > 0)
    $time_ago = $t . ' months';
  else if (($t = $diff->format("%d")) > 0)
    $time_ago = $t . ' days';
  else if (($t = $diff->format("%H")) > 0)
    $time_ago = $t . ' hours';
  else
    $time_ago = 'minutes';

  return $time_ago . ' ago (' . $date->format('M j, Y') . ')';
}

I liked Mithun's code, but I tweaked it a bit to make it give more reasonable answers.

function getTimeSince($eventTime)
{
    $totaldelay = time() - strtotime($eventTime);
    if($totaldelay <= 0)
    {
        return '';
    }
    else
    {
        $first = '';
        $marker = 0;
        if($years=floor($totaldelay/31536000))
        {
            $totaldelay = $totaldelay % 31536000;
            $plural = '';
            if ($years > 1) $plural='s';
            $interval = $years." year".$plural;
            $timesince = $timesince.$first.$interval;
            if ($marker) return $timesince;
            $marker = 1;
            $first = ", ";
        }
        if($months=floor($totaldelay/2628000))
        {
            $totaldelay = $totaldelay % 2628000;
            $plural = '';
            if ($months > 1) $plural='s';
            $interval = $months." month".$plural;
            $timesince = $timesince.$first.$interval;
            if ($marker) return $timesince;
            $marker = 1;
            $first = ", ";
        }
        if($days=floor($totaldelay/86400))
        {
            $totaldelay = $totaldelay % 86400;
            $plural = '';
            if ($days > 1) $plural='s';
            $interval = $days." day".$plural;
            $timesince = $timesince.$first.$interval;
            if ($marker) return $timesince;
            $marker = 1;
            $first = ", ";
        }
        if ($marker) return $timesince;
        if($hours=floor($totaldelay/3600))
        {
            $totaldelay = $totaldelay % 3600;
            $plural = '';
            if ($hours > 1) $plural='s';
            $interval = $hours." hour".$plural;
            $timesince = $timesince.$first.$interval;
            if ($marker) return $timesince;
            $marker = 1;
            $first = ", ";

        }
        if($minutes=floor($totaldelay/60))
        {
            $totaldelay = $totaldelay % 60;
            $plural = '';
            if ($minutes > 1) $plural='s';
            $interval = $minutes." minute".$plural;
            $timesince = $timesince.$first.$interval;
            if ($marker) return $timesince;
            $first = ", ";
        }
        if($seconds=floor($totaldelay/1))
        {
            $totaldelay = $totaldelay % 1;
            $plural = '';
            if ($seconds > 1) $plural='s';
            $interval = $seconds." second".$plural;
            $timesince = $timesince.$first.$interval;
        }        
        return $timesince;

    }
}

You can get a function for this directly form WordPress core files take a look here

http://core.trac.wordpress.org/browser/tags/3.6/wp-includes/formatting.php#L2121

function human_time_diff( $from, $to = '' ) {
    if ( empty( $to ) )
        $to = time();

    $diff = (int) abs( $to - $from );

    if ( $diff < HOUR_IN_SECONDS ) {
        $mins = round( $diff / MINUTE_IN_SECONDS );
        if ( $mins <= 1 )
            $mins = 1;
        /* translators: min=minute */
        $since = sprintf( _n( '%s min', '%s mins', $mins ), $mins );
    } elseif ( $diff < DAY_IN_SECONDS && $diff >= HOUR_IN_SECONDS ) {
        $hours = round( $diff / HOUR_IN_SECONDS );
        if ( $hours <= 1 )
            $hours = 1;
        $since = sprintf( _n( '%s hour', '%s hours', $hours ), $hours );
    } elseif ( $diff < WEEK_IN_SECONDS && $diff >= DAY_IN_SECONDS ) {
        $days = round( $diff / DAY_IN_SECONDS );
        if ( $days <= 1 )
            $days = 1;
        $since = sprintf( _n( '%s day', '%s days', $days ), $days );
    } elseif ( $diff < 30 * DAY_IN_SECONDS && $diff >= WEEK_IN_SECONDS ) {
        $weeks = round( $diff / WEEK_IN_SECONDS );
        if ( $weeks <= 1 )
            $weeks = 1;
        $since = sprintf( _n( '%s week', '%s weeks', $weeks ), $weeks );
    } elseif ( $diff < YEAR_IN_SECONDS && $diff >= 30 * DAY_IN_SECONDS ) {
        $months = round( $diff / ( 30 * DAY_IN_SECONDS ) );
        if ( $months <= 1 )
            $months = 1;
        $since = sprintf( _n( '%s month', '%s months', $months ), $months );
    } elseif ( $diff >= YEAR_IN_SECONDS ) {
        $years = round( $diff / YEAR_IN_SECONDS );
        if ( $years <= 1 )
            $years = 1;
        $since = sprintf( _n( '%s year', '%s years', $years ), $years );
    }

    return $since;
}

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"

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

Answer 5

Use This one and you can get the

    $previousDate = '2013-7-26 17:01:10';
    $startdate = new DateTime($previousDate);
    $endDate   = new DateTime('now');
    $interval  = $endDate->diff($startdate);
    echo$interval->format('%y years, %m months, %d days');

Refer this http://ca2.php.net/manual/en/dateinterval.format.php

Wrote my own

function getElapsedTime($eventTime)
{
    $totaldelay = time() - strtotime($eventTime);
    if($totaldelay <= 0)
    {
        return '';
    }
    else
    {
        if($days=floor($totaldelay/86400))
        {
            $totaldelay = $totaldelay % 86400;
            return $days.' days ago.';
        }
        if($hours=floor($totaldelay/3600))
        {
            $totaldelay = $totaldelay % 3600;
            return $hours.' hours ago.';
        }
        if($minutes=floor($totaldelay/60))
        {
            $totaldelay = $totaldelay % 60;
            return $minutes.' minutes ago.';
        }
        if($seconds=floor($totaldelay/1))
        {
            $totaldelay = $totaldelay % 1;
            return $seconds.' seconds ago.';
        }
    }
}
