Get a setting into perch_collection's 'each' callback

How do I pass a setting into the 'each' callback of perch_content_custom?

  $currentCat = getThemeCat();
  $doThat = true;
  $items = perch_collection('Beispiele', [
    'skip-template' => true,
    'category' => $currentCat,
    'sort'=>'projectTitle',
    ),
    'each' => function($item) {
      if(!empty($doThat)){
        // do that
      }
      else {
        // do this
      }
    },
  ],true);

The part that's not working is the if(!empty($doThat)) bit, probably because $doThat is not in the scope of the 'each' callback.

Is there a recommended way to pass $doThat into the callback?

Got it! The callback is called a closure, and it can access variables outside it's scope with the "use" keyword:

  $currentCat = getThemeCat();
  $doThat = true;
  $items = perch_collection('Beispiele', [
    'skip-template' => true,
    'category' => $currentCat,
    'sort'=>'projectTitle',
    ),
    'each' => function($item) use($doThat) {
      if(!empty($doThat)){
        // do that
      }
      else {
        // do this
      }
    },
  ],true);

And then it turned out I don't really need to do that :-)
