Very simple to use.

**Calling:**

    $files = dirContents(DIR_PATH, [FILTER, [TYPE]]);

**Examples:**

    $files = dirContens("my-dir");
_$files_ is array containing all, both files either directories

    $files = dirContens("my-dir", "img[0-9]");
_$files_ is array containing files or directories with 'img0', 'img1', 'img2', etc. in their names

    $files = dirContents("my-dir/", "\.php", 1);
_$files_ is array containing only files with '.php' in their names

**Tip:**
After calling _dirContents()_ try to call *print_r* for showing the array of files

    echo '<pre>';
    print_r($files);
    echo '</pre>';
