create tree from mysql results

[kosmidd]

Here is what I want to do:
Lets say I have this table (or returned recordset)
A | A | B | C | C
1 | 2 | 1 | 3 | 5
i | ii | ii | i | iv

This is translated into to a tree like this:

A
  +-1
      +-i
  +-2
      +-ii
B
  +-1
      +-ii
C
  +-3
     +-i
  +-5
      +-iv

I am trying actually to convert the above table into a multidimensional array.
Then the array will be convertet to a tree using <ul>.
You can see the result here : http://www.e-forologia.gr/seminaria/new,
but this is not done exactly with this way. I used recursive functions.
I want to make a class to pass the table and return this

	function Table2Array($TreeTable) {
		$iDepth=mysql_num_fields($TreeTable);
		$iRows=mysql_num_rows($TreeTable);
		/*Create Field array*/
		$arFields=Array();
		for($i=0; $i<$iDepth; $i++){
			${arField.$i}=Array();
			array_push($arFields,${arField.$i});
		}

	while($arRow=mysql_fetch_array($TreeTable)) {
		for($i=0; $i<count($arFields); $i++) {
			array_push($arFields[$i],$arRow[$i]);
		}
	}
