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. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=25530&edit=1
