Add 1 hour to current DateTime in PHP - Call to a member function add() on a non-object

Question

I've tried multiple examples/questions around and so far I cannot get this to work. i am trying to take the current DateTime, add 1 hour, then set the minutes to 30. Here is what I have:

Current Time:

$date = date('Y-m-d h:i:s'); //this works and echos properly

Add hour:

$date->add(new DateInterval("PT1H"));

I receive the following error

Call to a member function add() on a non-object

Then once that is done I'm planning to add:

$date->format('Y-m-d h:30:00'); //commented out on my script until I get the above piece working.

date() does not produce a DateTime() object which is required to use DateTime::add(). Change:

$date = date('Y-m-d h:i:s');

to

$date = new DateTime();

Try doing:

$date = new DateTime('NOW');
$date->add(new DateInterval("PT1H"));

`'NOW'` is not necessary. An empty constructor defaults to "now". – John Conde Jul 07 '15 at 18:12

Yup, you are right! It isn't wrong to add it though. – Mindastic Jul 07 '15 at 18:14
