减去发布多少分钟前的时间[重复]

Question

This question already has an answer here:

• Calculate relative time in C# 37 answers
• How to display “12 minutes ago” etc in a PHP webpage? [closed] 3 answers

So my current $item['date'] function gets the time and date of the post in this format Y-m-d H:i:s.

I want to display how many minutes was the post posted or if it is more than 24 hours, how many days ago was it posted OR like 0 days and 20 hours ago? something like that

Why doesn't the minus operator work here my code?

My current code:

<p><?php echo date('Y-m-d H:i:s') - $item['date'] ?> minutes ago</p>

</div>

I usually use this function. Use it like this time_ago('2014-12-03 16:25:26')

function time_ago($date){
    $retval = NULL;
    $granularity=2;
    $date = strtotime($date);
    $difference = time() - $date;
    $periods = array('decade' => 315360000,
        'year' => 31536000,
        'month' => 2628000,
        'week' => 604800, 
        'day' => 86400,
        'hour' => 3600,
        'minute' => 60,
        'second' => 1);

    foreach ($periods as $key => $value) 
    {
        if ($difference >= $value) 
        {
            $time = round($difference/$value);
            $difference %= $value;
            $retval .= ($retval ? ' ' : '').$time.' ';
            $retval .= (($time > 1) ? $key.'s' : $key);
            $granularity--;
        }
        if ($granularity == '0') { break; }
    }
    return $retval.' ago';      
}
