I am trying to calculate the difference between $timenow and $time.
$time = 2016-09-15 20:10:35
$timenow = 2016-09-15 20:40:42
I converted them to dateTime.
$time = new DateTime($time);
$timenow = new DateTime($timenow);
And then did the calculation:
$interval = $timenow->diff($time);
echo $interval;
Error: Catchable fatal error: Object of class DateInterval could not be converted to string
I looked at these difference between 2 timestamps in php and Wrong hour difference between 2 timestamps (hh:mm:ss)
Those didn't help.
