PHP Bug Type: Reproducible crash
Bug description: Calculation not taking place
Description:
------------
This code is part of a larger while loop which stops when "$dayloop ==
false".
This page is a report of employee clock-in and clock-out times. It shows
the employee, followed by each day that the report includes, and their
times.
This code works in some circumstances, but most of the time, the 3rd line
simply does not execute, or rather the value is never updated - thus
resulting in an endless loop (because $dayloop stays true).
It used to work perfectly (for over 6 months...) on several versions of
PHP, so I do not believe this to be something version-related.
Reproduce code:
---------------
At this point, $thisday would be a date in the format "YYYY-mm-dd".
$timestamp = strtotime($thisday);
$timestamp = $timestamp + (60 * 60 * 24); <-- this line does not work
if ($timestamp > strtotime($enddate)) {
$dayloop = false;
}
$thisday = date("Y-m-d", $timestamp); <-- creates the above value
Expected result:
----------------
$timestamp = $timestamp + (60 * 60 * 24)
I expect the value of $timestamp to increase by 86400.
Actual result:
--------------
Sometimes the code works for a few cycles, but eventually it will stop
incrementing the value of $timestamp and the script will time out.
