# Directory Helper

The Directory Helper file contains functions that assist in working with directories.

- Loading this Helper
- Available Functions

## Loading this Helper

This helper is loaded using the following code:

    $this->load->helper('directory');

## Available Functions

The following functions are available:

`directory_map`($source_dir[, $directory_depth = 0[, $hidden = FALSE]])

  Parameters: | $source_dir (string) – Path to the source directory $directory_depth (int) – Depth of directories to traverse (0 = fully recursive, 1 = current dir, etc) $hidden (bool) – Whether to include hidden directories
  Returns: | An array of files
  Return type: | array

  Examples:

      $map = directory_map('./mydirectory/');

  Note

  Paths are almost always relative to your main index.php file.

  Sub-folders contained within the directory will be mapped as well. If you wish to control the recursion depth, you can do so using the second parameter (integer). A depth of 1 will only map the top level directory:

      $map = directory_map('./mydirectory/', 1);

  By default, hidden files will not be included in the returned array. To override this behavior, you may set a third parameter to true (boolean):

      $map = directory_map('./mydirectory/', FALSE, TRUE);

  Each folder name will be an array index, while its contained files will be numerically indexed. Here is an example of a typical array:

      Array (
              [libraries] => Array
                      (
                              [0] => benchmark.html
                              [1] => config.html
                              ["database/"] => Array
                                      (
                                              [0] => query_builder.html
                                              [1] => binds.html
                                              [2] => configuration.html
                                              [3] => connecting.html
                                              [4] => examples.html
                                              [5] => fields.html

                                              [7] => queries.html
                                      )
                              [2] => email.html
