How to calculate minute difference between two date-times in PHP?
I think this will help you
function calculate_time_span($date){
$seconds = strtotime(date('Y-m-d H:i:s')) - strtotime($date);
$months = floor($seconds / (3600*24*30));
$day = floor($seconds / (3600*24));
$hours = floor($seconds / 3600);
$mins = floor(($seconds - ($hours*3600)) / 60);
$secs = floor($seconds % 60);
if($seconds < 60)
$time = $secs." seconds ago";
else if($seconds < 60*60 )
$time = $mins." min ago";
else if($seconds < 24*60*60)
$time = $hours." hours ago";
else if($seconds < 24*60*60)
$time = $day." day ago";
else
$time = $months." month ago";
return $time;
}
