php - Get List Of First Children Directory Names

Question

How to get a list of first children directory names inside a directory?

Here is an example tree:

dir / dir_first a / dir second aa dir second ab dir second ac dir_first b / dir second ba dir second bb dir second bc dir first c / dir second ca dir second cb dir second cc

I found the way of iterating through the dir here, but this is listing all the second level childrens too and also their full paths, while I want only the directory's name like dir_first a etc.:

$iterator = new RecursiveIteratorIterator( new RecursiveDirectoryIterator($dir_path), RecursiveIteratorIterator::SELF_FIRST); foreach($iterator as $file) { if($file->isDir()) { echo $file->getRealpath(); } }

If I understand your question right and you need same thing that is output right now but without the full path - use basename. echo basename($file->getRealpath()); — DannyPhantom

isn't it will output the last or in this case the second level directories? — Ari

glob allows you to enter a path and then use a flag to return only directories.

$files = glob('mydir/*',GLOB_ONLYDIR); var_dump($files);

o, yes! that is! is there a way to select the output order? I mean ascending or descending? I am still prefer to use the RecursiveDirectoryIterator, but I will accept this if this is the only way.

The GLOB_NOSORT will return the files in the order listed in the directory. If that doesn't work the way you want it to, you could use PHP's sort functions.
