Marcus,
some facts:
1. you CAN return 'proper' values from a recursive function call.
2. you DONT need a recursive function call to retrieve the properties
of these objects.
3. you DONT need a recursive function to build a nested data structure
(using the parent<->child ID relationship)
with regard to number 3 try having a look at the following code
snippet (I leave it as an exercise to you to figure out how to
translate it to your own situation (my example happens to
use arrays because that's how the data was retrieved from a DB,
you'll want to stick with the collection of objects you get bgack from
the SOAP call - the principle is the same):
the trick is the use of the $parents 'stack' (array) in conjunction
with references to track parents ...
// return data array (will contain a nested structure)
$data = array();
$parents = array();
while(!empty($rows)) {
foreach ($rows as $key => $row) {
// add some tree related elements with default values.
$row['selected'] = false;
$row['childselected'] = false;
$row['children'] = array();
if (!$row['parentid']) {
$dCount = count($data);
$data[ $dCount ] = $row;
$parents[ $row['nodeid'] ] =& $data[ $dCount ];
} else if (isset($parents[ $row['parentid'] ])) {
$dCount = count($parents[ $row['parentid'] ]['children']);
$parents[ $row['parentid'] ]['children'][ $dCount ] = $row;
$parents[ $row['nodeid'] ] =& $parents[ $row['parentid'] ]['children'][ $dCount ];
}
unset($rows[$key]);
}
}
