I didn't understand what to do with this statement:

RecursiveIteratorIterator::setMaxDepth ([ int $max_depth = -1 ] ) : void

So, after finding the answer, this is how you incorporate it (for anyone else who was stuck for a while like me!):

/ define the depth of the tree to which you want to search
/ where -1 = show all layers below the parent
/ and 1 = show the first layer, etc, etc
$max_depth = -1;  

/ set the path to the directory
$this_directory

/ do the search
$recursive = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($this_directory));

/ now adjust the contents to your desired depth
$recursive->setMaxDepth($max_depth);
