To scan the directory of a folder which is

Answer 1

The quick and dirty way:

$folders = glob("<path>/*", GLOB_ONLYDIR);

A more versatile and object-oriented solution, inspired by earlier answers using DirectoryIterator but slightly more concise and general purpose:

    $path = '<path>';
    $folders = [];

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

Answer 2

To determine whether or not you have a folder or file use the functions is_dir() and is_file()

For example:

$path = 'extracted/' . $name[0];
$results = scandir($path);

foreach ($results as $result) {
    if ($result === '.' or $result === '..') continue;

    if (is_dir($path . '/' . $result)) {
        //code to use if directory
    }
}

Answer 3

First off, rmdir() cannot delete a folder with contents. If safe mode is disabled you can use the following.

exec("rm -rf folder/"); 

Also look at is_dir()/is_file() or even better the PHP SPL.
