The datetime class needs to be run multiple times to get the NAN result (for ($a=0;$a<2;$a++){). Test script: --------------- for ($a=0;$a<2;$a++){ $lastResponse = date("Y-m-d"); $noResponse = date("Y-m-d"); $dateCreated = new DateTime(date("Y-m-d", strtotime($lastResponse))); $dateNotCreated = new DateTime(date("Y-m-d", strtotime($noResponse))); $today = new DateTime(date("Y-m-d")); if(isset($lastResponse)) { $diff = $today->diff($dateCreated); } else { $diff = $today->diff($dateNotCreated); } } echo 240 / 23; Expected result: ---------------- Not NAN Actual result: -------------- NAN ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=52920&edit=1
