    Number of Subdirectories in Themes Directory
    The function below informs about the number of subdirectories in the themes directory. Note that this doesn’t necessarily match the number of themes recognized by WordPress.

    <?php
    function display_themes_subdirs_count_info()
      $theme_root = get_theme_root();
      $files_array = glob("$theme_root/*", GLOB_ONLYDIR);
      echo "There are " . count($files_array) . " subdirectories in the " . $theme_root . " directory"; 
    }
    ?>
    

    Example output:

    There are 5 subdirectories in the /home/user/public_html/wp-content/themes directory.
