PHP only first level of subdirectories into an array

Question

I'm trying to get only the first level of subdirectories into an array. Does someone know a slimmer and faster way to do this?

    $dirs =  new RecursiveDirectoryIterator('myroot', RecursiveDirectoryIterator::SKIP_DOTS);
    $files = new RecursiveIteratorIterator($dirs, RecursiveIteratorIterator::SELF_FIRST);

    $dir_array = array();
    foreach( $files AS $file) 
    {           
        if($files->isDot()) continue;
        if($files->getDepth() > 0) continue;

        if( $files->isDir() )
        {
            $dir_array[] = $file->getFilename();
        }
    }

Simple as this:

$array = glob('myroot/*', GLOB_ONLYDIR);

To get only the base directory name and not the full path:

$array = array_map('basename', glob('myroot/*', GLOB_ONLYDIR));

See http://php.net/glob

yes, absolutely. There are iterators for recursively iterating as you already know.

ok, but that gives me the full paths rather than an array with only the subdir names like above.

@Mike: Map the array with basename
