Sort array of objects by date field

Question

How can I re-arrange a array of objects like this:

 [495] => stdClass Object
        (
         [date] => 2009-10-31 18:24:09
         ...
        )
 [         


        

Answer 1

I wanted to expand on arnaud576875 and Michael Irigoyen.

Same issue with object containing dateTime with Symphony.

I coudn't use $a['date'] because it was not an key array.

usort($verifications, function($a, $b) {
   return $a->getDate()->format('U') - $b->getDate()->format('U');
});

This solved my problem
