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);
