php RecursiveDirectoryIterator:如何排除带有点和双点的目录路径


php RecursiveDirectoryIterator: how to exclude directory paths with a dot and double dots?

RecursiveDirectoryIterator似乎给了我来自本地主机和实时服务器的两个不同的结果,

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);

本地主机,

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

实时服务器,

(
    [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/../
)

那么,如何排除带有点和双点的目录路径?

编辑:

实时服务器 - PHP 版本 5.3.27本地主机 - PHP 版本 5.5

尝试:

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