<?php

// Connect to FTP server

// Assign ftp server to the variable
$ftp_server = "ftp.xxxxxxx.com";

// Use correct ftp username
$ftp_username = "yyyyy";

// Use correct ftp password corresponding
// to the ftp username
$ftp_userpass = "zzzzz";

// Folder contains subfolders and files into it
$filesAndFolders = "/public_html/yourfolder";

// Establishing ftp connection
$ftp_connection = ftp_connect($ftp_server)
    or die("Could not connect to $ftp_server");

if ($ftp_connection) {
    echo "successfully connected to the ftp server!";

    // Logging in to established connection with
    // ftp username and password
    $login = ftp_login($ftp_connection, $ftp_username, $ftp_userpass);

    if ($login) {

        // Checking whether logged in successfully or not
        echo "<br>logged in successfully!";
        removeFtpFolders($ftp_connection, $filesAndFolders);
        echo "<br>Deleted!";
    } else {
        echo "<br>login failed!";
    }

    // Closing connection
    if (ftp_close($ftp_connection)) {
        echo "<br>Connection closed Successfully!";
    }
}

function removeFtpFolders($ftp_connection, $directory)
{
    if (count(ftp_mlsd($ftp_connection, $directory)) <= 2) {
        // folder is empty
        ftp_rmdir($ftp_connection, $directory);
    } else {
        $lists = ftp_mlsd($ftp_connection, $directory);

        foreach ($lists as $key => $list) {
            $subFolderPath = $directory . '/' . $list['name'];
            // finding subfolders
            if ($list['type'] == 'dir') {
                removeFtpFolders($ftp_connection, $subFolderPath);
            } else {
                // delete file
                ftp_delete($ftp_connection, $subFolderPath);
            }
        }
