How to list files inside public folder?

I have a persistent volume defined in server under www/public/images/logo/

I want to list all the files inside that folder. So far I have done following lines with no luck.

public function getFiles($url) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_URL, $url);

    $data = curl_exec($ch);
    curl_close($ch);

    return $data;
}


    $url = 'https://myurl.de/images/logo/';

    $data = $this->getFiles($url);

Can anybody please help ?

Answer

If you are want to list all files on same server then you can use php function scandir();

If you are want to list all files on remote server then you need to connect it using ftp like below code.

    $connection = ftp_connect("HOST_NAME");
    $login = ftp_login($connection, "FTP_USERNAME","FTP_PASSWORD");
    ftp_pasv($connection, true);
    $fileList = ftp_nlist($connection,'DIRECTORY_ON_FTP');
    ftp_close($connection);
