A validity enhancement to the previous note using is_numeric in addition to checkdate:
Since the checkdate function has a bug in it (bug #25530), I think you should be checking for
is_int() instead of is_numeric(), at least before the bug is fixed.
// Example 1
$day = "4e4";
$mon = "5";
$year = "2000";
if (is_numeric($day) && is_numeric($mon) &&
is_numeric($year) && checkdate( $mon, $day, $year ))
{
echo "Valid 1";
}
// Result: prints 'Valid 1'
// Example 2
if (is_int($day) && is_int($mon) &&
is_int($year) && checkdate( $mon, $day, $year ))
{
echo "Valid 2";
}
// Result: prints nothing
I hope you can see the difference.
