dynamic numbered list

[mykg4orce]

I have a function that calls itself to create the following structure for a tree menu.

About
[INDENT]History
[INDENT]Working here[/INDENT]
Careers
[INDENT]Postings[/INDENT][/INDENT]

Investors
[INDENT]Financial
[INDENT]Annual Report[/INDENT][/INDENT]

I need to number the above like below:

1. About
   [INDENT]1.1 History
   [INDENT]1.1.1 Working here[/INDENT]
   1.2 Careers
   [INDENT]1.1.2 Postings[/INDENT][/INDENT]

2. Investors
   [INDENT]2.1 Financial
   [INDENT]2.1.1Annual Report[/INDENT][/INDENT]

here is the PHP function that generates the unordered list

function specs($parent_id, $cabinet_id) {
	global $_CONFIG;
	$db = new DB('mysql');

$db->query("SELECT something semething");


while ($data = $db->results()) {
	echo '<ul>';

	echo '<li>'.$data['name'].'</li>';
	// recall tree on any child ids 
	// this will delete the family recursivley

	specs($data['content_id'], $cabinet_id);		
	echo '</ul>';
}
}

I have tried several methods but can not figure out how to make the numbering recursive.

here is the solution

function specs($parent_id, $cabinet_id, $j=NULL) {
	global $_CONFIG;
	$db = new DB('mysql');


$db->query("SELECT something");

$i=1;

while ($data = $db->results()) {
	echo '<div style="padding-left:20px;">';


	if (isset($j)) {
		echo '<strong>'.$j.'.'.$i.'</strong> ';
		$parent = $j.'.'.$i;
	} else {
		echo '<strong>'.$i.'</strong> ';
		$parent = $i;
	}

	echo $data['name'].'<br />';



	specs($data['content_id'], $cabinet_id, $parent);		
	echo '</div>';

	$i++;
}
}
