What about first converting the integer to a date using the "date"
function. From here you can see if it validates to a real date by
using PHP's built-in "checkdate" function, and then go from there. You
will have to do additional testing if the converted integer from the
first step turns out to be "12-31-1969," as most numbers 5-digits or
less will.
ie
date('m-d-Y',12345) returns "12-31-1969"
