If I try
```
$docArray = $modx->getCollection('modResource',array(
    'parent' => 3,
    'published' => 1,
    'hidemenu' => 0
));
```
and I print_r the results, I get this absolutely appalling array of objects in return, consisting of 157,858 lines, with the entire site's alias maps and cached elements, as well as 156 lines consisting of *RECURSION*, whatever that may mean! All to simply get a collection which I would expect to consist of four resource objects???

How can I go about getting the IDs of the children of #3 that fit certain criteria, without this kind of outrageous bloat?

Ok, getChildIds(...) is what I want.

Turns out getChildIDs alone doesn't do what I want; a StackOverflow response let me to this, giving me a list of resources not showing in menus like My Resources, Your Resources, Our Resources, ...
```
<?php
$array_ids = $modx->getChildIds(3, 2, array('context' => 'web',));

$docs = $modx->getCollection('modResource', array(
    'id:IN' => $array_ids
    ,'hidemenu: =' => 1
    ,'pagetitle: LIKE' => '%Resources'
));

foreach ($docs as $doc) {
    $output .= $doc->get('pagetitle') . '<br/>';
}

return $output;
```
