Bug description: Function checkdate() accepts float values as valid parameters
Description:
------------
Function checkdate(mon, day, year) accepts float values as valid
parameters.
Reproduce code:
---------------
$day1 = 13.7;
$mon1 = 5.1;
$year1 = 2000.75;
if (checkdate($mon1, $day1, $year1))
echo "Valid date";
else
echo "Invalid date";
$day2 = "4e4";
$mon2 = 5.1;
$year2 = "2000.75";
if (checkdate($mon2, $day2, $year2))
echo "Valid date";
else
echo "Invalid date";
Expected result:
----------------
I expected the script to echo two times 'Invalid date' since only integer
parameters should be accepted.
Actual result:
--------------
The script echoed two times 'Valid date'. The first date is a clear case.
I guess the second date is considered valid because of the string "4e4"
being taken as "4" (the number 4), which is also wrong.
