codeigniter get directory info in view - php

Question

I'm essentially having difficulty pass dynamic variables to a view.
I have php functions as the following:
public function scandir_recursive($directory, $filter=FALSE)
{
// if the path has a slash at the end we remove it here
if(substr($directory,-1) == '/')
{
$directory = substr($directory,0,-1);
}
// if the path is not valid or is not a directory ...
if(!file_exists($directory) || !is_dir($directory))
{
// ... we return false and exit the function
return FALSE;
// ... else if the path is readable
}elseif(is_readable($directory))
{
// initialize directory tree variable
$directory_tree = array();
// we open the directory
$directory_list = opendir($directory);
// and scan through the items inside
while (FALSE !== ($file = readdir($directory_list)))
{
// if the filepointer is not the current directory
// or the parent directory
if($file != '.' && $file != '..')
{
// we build the new path to scan
$path = $directory.'/'.$file;
// if the path is readable
if(is_readable($path))
{
// we split the new path by directories
$subdirectories = explode('/',$path);
// if the new path is a directory
if(is_dir($path))
{
// add the directory details to the file list
$directory_tree[] = array(
'path' => $path,
'name' => end($subdirectories),
'kind' => 'directory',
// we scan the new path by calling this function
'content' => scandir_recursive($path, $filter));
// if the new path is a file
}elseif(is_file($path))
{
// get the file extension by taking everything after the last dot
$extension = end(explode('.',end($subdirectories)));
// if there is no filter set or the filter is set and matches
if($filter === FALSE || $filter == $extension)
{
// add the file details to the file list
$directory_tree[] = array(
'path' => $path,
'name' => end($subdirectories),
'extension' => $extension,
'size' => filesize($path),
'kind' => 'file');
}
}
}
}
}
// close the directory
closedir($directory_list);
// return file list
return $directory_tree;
// if the path is not readable ...
}else{
// ... we return false
return FALSE;
}
}
</code>
I need to make such a function operable in the sense I can echo the data retrieved from the directories recursively and pass this data to the view.

In the controller do the following:
$data['directory_tree'] = scandir_recursive($directory);
$this->load->view('my_view', $data);
In the view you can access the variable like this:
echo $directory_tree['path'];
