PHP DateTime Functions

Question

I have the following code fragment:

$now = '2011-12-01 22:32:33';
$datetime = '2011-12-01 00:07:27';  


$nowObj = new DateTime($now);
$datetimeObj = new DateTime($datetime);

$diff = $datetimeObj->diff($nowObj); //leaving this in screws up the next line

number_format(1134); //this becomes NaN

When I am running through this code and leave the $diff = ... line in, it messes with other numbers and math that I do later in the code. For instance, my number_format(1134); later on becomes NaN. I am using a XAMPP stack with PHP 5.3.1. Is this a bug?

Answer 1

Could this be related, hmm ...

If you are on windows, I would make sure time zone settings are set correctly. The comments on php.net point out a couple of quirks and buggy behavior under windows, maybe seriously consider using an alternate method for diffing your dates if issues persist.
