Question

The function below returns all folders in a given directory down to multiple levels.

I only need one level depth though, just folders in the target directory, no subfolders.

Also the function returns the full path to the folder, I only want the folder name. I’m sure I’m missing something simple.

How can I modify the function to return only the folder names of the given directory? (not the full paths to each folder)

$myArray = get_dirs(‘../wp-content/themes/mytheme/images’);

<?php
  function get_dirs( $path = '.' ){
    return glob( 
      '{' . 
        $path . '/*,'    . # Current Dir
        $path . '/*/*,'  . # One Level Down
        $path . '/*/*/*' . # Two Levels Down, etc.
      '}', GLOB_BRACE + GLOB_ONLYDIR );
  }
?>

btw, thanks to Doug for the original function help!

Instead of using glob(), I would suggest using the DirectoryIterator class.

function get_dirs($path = '.') {
    $dirs = array();

    foreach (new DirectoryIterator($path) as $file) {
        if ($file->isDir() && !$file->isDot()) {
            $dirs[] = $file->getFilename();
        }
    }

    return $dirs;
}
