php RecursiveDirectoryIterator：ドットとダブルドットでディレクトリパスを除外する方法は？

Question

RecursiveDirectoryIterator

define ('WEBSITE_DOCROOT', str_replace('\\', '/', dirname(__FILE__)).'/'); 

print_r(WEBSITE_DOCROOT); 

// List all the class directories in the array. 
$main_directories = array(
    'core/model/', 
    'core/helper/', 
    'core/ext/' 
); 

// Set other vars and arrays. 
$sub_directories = array(); 

// List any sub dirs in the main dirs above and store them in an array. 
foreach($main_directories as $path_directory) 
{ 
    $iterator = new RecursiveIteratorIterator 
    (
     new RecursiveDirectoryIterator(WEBSITE_DOCROOT.$path_directory), // Must use absolute path to get the files when ajax is used. 
     RecursiveIteratorIterator::SELF_FIRST 
    ); 

    foreach ($iterator as $fileObject) 
    { 
     if ($fileObject->isDir()) 
     { 
      //if($fileObject->isDir() === '.' || $fileObject->isDir() === '..') {continue;} 

      // Must trim off the WEBSITE_DOCROOT. 
      $sub_directories[] = preg_replace('~.*?(?=core|local)~i', '', str_replace('\\', '/', $fileObject->getPathname())) .'/'; 
     } 
    } 
} 

// Mearge the main dirs with any sub dirs in them. 
$merged_directories = array_merge($main_directories,$sub_directories); 
print_r($merged_directories); 

がローカルホスト、

(
    [0] => core/model/ 
    [1] => core/helper/ 
    [2] => core/ext/ 
) 

ライブサーバー、だから、

(
    [0] => core/model/ 
    [1] => core/helper/ 
    [2] => core/ext/ 
    [3] => core/model/./ 
    [4] => core/model/../ 
    [5] => core/helper/./ 
    [6] => core/helper/../ 
    [7] => core/ext/./ 
    [8] => core/ext/../ 
) 

、どのように私は除外することができ、私に私はlocalhostとライブサーバーからの二つの異なる結果を与えているようですディレクトリパスとドットとダブルドット？

EDIT：

ライブサーバー - PHPのバージョン5.3.27 ローカルホスト - PHPのバージョン5.5

で試してみてください：

new RecursiveDirectoryIterator(WEBSITE_DOCROOT.$path_directory, RecursiveDirectoryIterator::SKIP_DOTS);
