categories listing

I'd like to print a list of all terms of a vocabulary, since i need to show a links collection to all categories. I used this snipped in my php page:

			
			$termini = taxonomy_get_tree(3);
			var_dump(($termini[0]));
			$limite = count($termini);
			for($i=0; $i < $limite; $i++) print $termini[$i]["name"];

var_dump() shows me the entire struct:

object(stdClass)(7) { ["tid"]=> string(1) "4" ["vid"]=> string(1) "3" ["name"]=> string(8) "speciale" ["description"]=> string(0) "" ["weight"]=> string(1) "0" ["depth"]=> int(0) ["parents"]=> array(1) { [0]=> string(1) "0" } }

problems:

1. $termini[$i]["name"] doesnt work. why i cant access object atributes? i tried also $termini[$i].name but...same results

2. i need a links collection associative array to pass to theme('links', $collections) function. how this array has to be formed?

tnx for help! :)
