DateInterval string Problems

Question

I'm trying to do a math problem using datetime in php. The problem that the string that I'm creating is dynamic. If I add as a static string it runs fine, but If I make the string dynamic it fails. Here's a code example.

 $now = new DateTime();
$datetime_interval = 'P' . $filledOrder->hours . 'H'; // hours comes from an object
$now->add(new DateInterval($datetime_interval));

If I add static string to DateInterval is working fineenter code here

$now->add(new DateInterval('P10H'));

Any help would be greatly appreciated.

Do you get an error? If `$filledOrder->hours` was null or empty that would lead to sth. like bad format error. Also note your (static) format is incorrect: From the interval spec: "If the duration contains time elements, that portion of the specification is preceded by the letter T". So it should be 'PT' . $hours . 'H' — macghriogair, Jun 09 '17 at 20:17
No I'm not getting an error and when I debug I see that the property of that object does have a value — Eric Evans, Jun 09 '17 at 20:22

You Should consider entering full string as format like this way.
