Bug Type: Bug
Bug description:Division equations are overridden
Description:
------------
The result of this equation (echo 240 / 23;) is NAN in each occurrence when
I run DateTime class before the equation. 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
