It is possible with PHP when that 'start' date and the 'end' date are known
BEFORE the user requests that page. Simply generate all possible dates
between those two values, and commit them to select boxes. If they're not
known, or they cross month or year barriers, you'll have to rely on
javascript to limit the options (and make unlimited options available
without javascript, on a date outside the possibilities you will produce an
error on submitting).

Ofcourse, on submitting, whether javascript is enabled or not, you'll
always have to check start, interim, and end date on submitting to make
sure it's valid.

On HOW to make a date confirm by js, I'd suggest a trip to
comp.lang.javascript.
