Make a recursive function which work on global var or on var passed on reference
function rec($parent_id, &$the_parent_array){
/// select name, theme_id from some_table where par_id=$parent_id;
while ($arr = mysql_fetch_assoc($res)){
$the_parrent_array[$arr['theme_id']]=array('name'=>$arr['name']);
rec($arr['theme_id'],$the_parent_array[$arr['theme_id']']);
}
}
$your_array = array();
rec(1,$your_array);
