Some Possible PHP in Templates

I've read the posts around here concerning PHP in templates and found that it is nearly impossible. I was wondering if there were possibly ways around it. Here's what I'm trying to do:

I'm designing a new feature for our RX-8 Club. It allows you to add your vehicle information into your profile. We have three types of owners we're aiming at: Mazda Protege, Mazda RX-7, and Mazda RX-8. Now... when a user's goes to add their car, they have 4 HTML form boxes: Year, Model, Color, and Options. These boxes are automatically filled from an SQL database when they select a certain item. Such as, if they select 2004, only the Prot?g? and RX-8 will be available Models... If they Select 1995, only the Prot?g? and the RX-7 will be available Models... and so on for Color and Options. Now - These HTML select boxes operate off of PHP code. This is an example of one of the select boxes' code:

<?php
SelectBox ("Year", "reg_caryear");
?>

That's for the Vehicle Year (also has Model, Color, Options). Then, also I need this PHP function:

<?php
function SelectBox( $Label, $selectName ){
?>
<tr ALIGN="LEFT">
<td width="15%"><?php echo $Label ?></td>
<td align="left">
<select name="<?php echo $selectName ?>">
<option></option><option></option><option></option>
<option>--------- Not Yet Loaded ---------</option>
</select>
</td>
</tr>
<?php
}
?>

Here's a demo of what I'm talking about:

Is this possible any other way? This is the only way I have figured out how to do auto-populated form boxes... Thanks everyone for your help.

to my knowledge the closest you'll get is the 'conditional templates hack' but don't quote me on that

sabe is right. Except that will only allow things such as
if ()
{

}

etc etc (IIRC)
