Hello,

I have this little function that work well for me, but I was 
wondering if it could be optimized. I use it to set the default value 
of checked radio buttons. Also, while doing this function, I 
discovered that PHP can autoinstantiate associative arrays in depth. 
For ex.

$ar = array ();
$ar['one']['two']['three'] = 'hello world';

echo $ar['one']['two']['three'];

--> hello world

I must say that PHP's array are one of the nicest feature of the language.

--------------------------------------------------------
Here's what it look inserted in the HTML page:
--------------------------------------------------------

<hr>
<form>
Are you ugly?
Yes
<input type="radio" name="choice_1" value="1" <?php echo 
$radioGroup['1']['1'] ?>>
No
<input type="radio" name="choice_1" value="1" <?php echo 
$radioGroup['1']['2'] ?>>
<hr>
Are you tall?
Yes
<input type="radio" name="choice_2" value="1" <?php echo 
$radioGroup['2']['1'] ?>>
No
<input type="radio" name="choice_2" value="1" <?php echo 
$radioGroup['2']['2'] ?>>
<hr>
Are you funny?
Yes
<input type="radio" name="choice_3" value="1" <?php echo 
$radioGroup['3']['1'] ?>>
No
<input type="radio" name="choice_3" value="1" <?php echo 
$radioGroup['3']['2'] ?>>
</form>

--------------------------------------------------------
And here's the function:
--------------------------------------------------------

function assignValues ($maxOutArrays, $maxInArrays, $arSelection) {

   $counter1   = 1;
   while ( $counter1 <= $maxOutArrays ) {

     $counter2 = 1;
     while ( $counter2 <= $maxInArrays ) {
       if ( !isset ($arSelection[$counter1][$counter2]) ) {
         $arSelection[$counter1][$counter2] = '';
       }
       $counter2++;
     }
     $counter1++;
   }
   return $arSelection;
}

$radioGroupDefaultValues['1']['2'] = 'checked';
$radioGroupDefaultValues['2']['1'] = 'checked';
$radioGroupDefaultValues['3']['1'] = 'checked';

$radioGroup = assignValues (3, 2, $radioGroupDefaultValues);

--------------------------------------------------------
And the output show with var_dump ($radioGroup)
--------------------------------------------------------

array(3) {
   [1]=>
   array(2) {
     [2]=>
     string(7) "checked"
     [1]=>
     string(0) ""
   }
   [2]=>
   array(2) {
     [1]=>
     string(7) "checked"
     [2]=>
     string(0) ""
   }
   [3]=>
   array(2) {
     [1]=>
     string(7) "checked"
     [2]=>
     string(0) ""
   }
}

Now I have a big form with 50 radio buttons in 10 groups of 5 radio 
buttons. I didn't benchmark this function, it seems that it run well, 
but if there is a better way to do it, I'd like to hear it.

TIA
