However, if the object is called elsewhere first (for example, in a var_dump() or json_encode()) the attributes can be tested with empty(). Tested on 5.3.3 and 5.5.9-ubuntu. Test script: --------------- <?php $date = new DateTime('2014-08-25'); $today = new DateTime('2014-08-29'); $interval = date_diff($date, $today); // json_encode($interval); if (!empty($interval->days)) { echo $interval->days; } else if (!empty($interval->h)) { echo $interval->h; } else { echo 'No matches'; } Expected result: ---------------- 4 Actual result: -------------- string: 'No matches' ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=67934&edit=1
