我基本上很难将动态变量传递给视图。

我有如下的php函数： 

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>

我需要使这样的函数可操作，因为我可以递归地回显从目录中检索到的数据并将这些数据传递给视图。

在控制器中执行以下操作：

$data['directory_tree'] = scandir_recursive($directory);
$this->load->view('my_view', $data);

在视图中，您可以像这样访问变量：

echo $directory_tree['path'];
