How do i convert the

Answer 1

There is a function format for this. But it wont return the number of seconds. To get number of seconds you use this technique

$seconds = abs($datetime1->getTimestamp()-$datetime2->getTimestamp());

If you really want to use $interval you need to calculate it.

$seconds = $interval->days*86400 + $interval->h*3600 
           + $interval->i*60 + $interval->s;

Here

• 86400 is the number of seconds in a day
• 3600 is the number of seconds in an hour
• 60 is the number of seconds in a minute
