logic issue

[lazzerous]

ok...

I have a multi-dimensional array that is completely dynamic in the size of it's attributes.

Here's an example of how part of one is set up:

$specs = array();
$specs[0][name] = "DC Connector";
$specs[0][options][0][value] = "DC";
$specs[0][options][0][description] = "DuraCon";
$specs[1][name] = "Insulator Type";
$specs[1][options][0][value] = "D";
$specs[1][options][0][description] = "Thermoplastic Glass Reinforced";
$specs[2][name] = "No. of Contacts";
$specs[2][options][0][value] = "9";
$specs[2][options][1][value] = "15";
$specs[2][options][2][value] = "21";
$specs[2][options][3][value] = "25";
$specs[2][options][4][value] = "31";
$specs[2][options][5][value] = "37";
$specs[2][options][6][value] = "51";
$specs[3][name] = "Contact Type";
$specs[3][options][0][value] = "P";
$specs[3][options][0][description] = "Pin (Plug)";
$specs[3][options][1][value] = "2";
$specs[3][options][1][description] = "Socket (Receptacle)";

As you might have guessed, this array is used to populate a dynamic number of select boxes.

The first show option for the user is a dash, meaning no selection for that option set.

Let's say the user selects 5 of the X options, and wants to see all remaining combinations, using what he/she has selected, and looping through all the possibilities of what he/she/ didnt select...

I know, this is a lot to take in...

With a static number of option sets, lets say 6, I know that I could put 6 for loops, all within each other
for() {
for () {
for () {
etc

However, with an unknown number of option sets (select boxes), and an unknown number of options within each of those option sets, how can I loop through everything and generate all remaining combinations?

Thank you all in advance for your assistance - I really appreciate it

Would using foreach help as a generic array iterator? Or [man]count[/man] to find out how many elements an array has?

makes sense - tis along the line i was going, but I cant seem to get my logic right...

I've re-arranged the multi-dimensional array to makes things easier on the eyes

here's how i have it set up right now:

<?
$optionsets[count] = "9";
$optionsets[0][0] = "DC";
$optionsets[1][0] = "D";
$optionsets[2][0] = "A";
$optionsets[3][0] = "9";
$optionsets[3][1] = "15";
$optionsets[3][2] = "21";
$optionsets[3][3] = "25";
$optionsets[3][4] = "31";
$optionsets[3][5] = "37";
$optionsets[3][6] = "51";
$optionsets[4][0] = "P";
$optionsets[4][1] = "S";
$optionsets[5][0] = "5";
$optionsets[5][1] = "6";
$optionsets[5][2] = "S";
$optionsets[6][0] = "E";
$optionsets[6][1] = "C";
$optionsets[7][0] = "B";
$optionsets[7][1] = "F";
$optionsets[7][2] = "R";
$optionsets[7][3] = "K";
$optionsets[7][4] = "L";
$optionsets[7][5] = "P";
$optionsets[8][0] = "00.5";
$optionsets[8][1] = "01.0";
$optionsets[8][2] = "02.0";
$optionsets[8][3] = "18.0";
$optionsets[8][4] = "24.0";
$optionsets[8][5] = "36.0";
$optionsets[8][6] = "48.0";
$optionsets[9][0] = "1";
$optionsets[9][1] = "2";
$optionsets[9][2] = "3";
$optionsets[9][3] = "4";
$optionsets[9][4] = "5";
$optionsets[9][5] = "System 1";

for($i=0; $i<$optionsets[count]; $i++)
	{
	${"on_$i"} = "0";
	}

for($i=0; $i<$optionsets[count]; $i++)
	{
	if ($i != "0")
		{
		for ($j=0; $j<$i; $j++)
			{
			if ($j > sizeof($optionsets[$j]))
				{
				$on = sizeof($optionsets[$j]);
				}
			else
				{
				$on = ${"on_j"}++;
				}
			echo $optionsets[$j][$on];
			}
		}


if (sizeof($optionsets[$i]) > ${"on_$i"})
	{
	$on = ${"on_i"}++;
	}
echo $optionsets[$i][${"on_$i"}];

for ($j=$i+1; $j<$optionsets[count]; $j++)
	{
	if ($j > sizeof($optionsets[$j]))
		{
		$on = sizeof($optionsets[$j]);
		}
	else
		{
		$on = ${"on_j"}++;
		}
	echo $optionsets[$j][$on];
	}

echo "<br>\n";
}
?>

This, currently, should show all possible combinations of all elements, with no limiter. However, the following is all it outputs:

DC15
D25
A51
9
P
5
E
B
00.5

I really should have paid more attention in math class back in college....
