Belajar PHP: Membuat Peta Folder (Map Directory)

Peta Folder atau Map Directory yang saya maksud adalah peta folder dan file yang ada pada suatu folder target, tersusun secara hierarkis dan dapat digunakan untuk keperluan lebih lanjut, seperti membangun interface treeview layaknya Windows Explorer.

Untuk membangun peta folder/map directory tersebut, saya menemukan fungsi menarik yang terpaketkan bersama CodeIgniter 2.0 (directory_helper.php). Berikut fungsinya:

[sourcecode language=”php”]
/**
* Create a Directory Map
*
* Reads the specified directory and builds an array
* representation of it. Sub-folders contained with the
* directory will be mapped as well.
*
* @access public
* @param string path to source
* @param int depth of directories to traverse (0 = fully recursive, 1 = current dir, etc)
* @return array
*/
function directory_map($source_dir, $directory_depth = 0, $hidden = FALSE)
{
if ($fp = @opendir($source_dir))
{
$filedata = array();
$new_depth = $directory_depth – 1;
$source_dir = rtrim($source_dir, DIRECTORY_SEPARATOR).DIRECTORY_SEPARATOR;

while (FALSE !== ($file = readdir($fp)))
{
// Remove ‘.’, ‘..’, and hidden files [optional]
if ( ! trim($file, ‘.’) OR ($hidden == FALSE && $file[0] == ‘.’))
{
continue;
}

if (($directory_depth < 1 OR $new_depth > 0) && @is_dir($source_dir.$file))
{
$filedata[$file] = directory_map($source_dir.$file.DIRECTORY_SEPARATOR, $new_depth, $hidden);
}
else
{
$filedata[] = $file;
}
}

closedir($fp);
return $filedata;
}

return FALSE;
}
[/sourcecode]

Untuk mencobanya, silakan buat satu script PHP kecil:
[sourcecode language=”php”]
$map =directory_map(‘./wp-admin’,2);
echo ‘<pre>’;
print_r($map);
echo ‘</pre>’;
[/sourcecode]

Contoh diatas akan membangun peta folder dari folder wp-admin dengan kedalaman hierarkis 2 layer. hasilnya:
