How to allow user to choose date/time - in PHP only?
<p>I want a complete server side solution, so no JS, etc.</p>

<p>All that I can think of is three combo boxes for day/month/tear, but of course the user can then select an invalid day/month combination.</p>

<p>What's the best way to let use select a date when I am not allowed to use any client side code?</p>
