How can you download an entire folder via FTP in PHP and save it locally?

To download an entire folder via FTP in PHP and save it locally, you can use the FTP functions in PHP to recursively download all files and subfolders within the specified folder. You will need to establish an FTP connection, navigate to the folder you want to download, retrieve a list of files and subfolders, and download each one individually. Finally, save the downloaded files to a local directory on your server.

<?php
// FTP server details
$ftp_server = 'ftp.example.com';
$ftp_user = 'username';
$ftp_pass = 'password';

// Local directory to save files
$local_dir = '/path/to/save/files/';

// Connect to FTP server
$ftp_conn = ftp_connect($ftp_server);
ftp_login($ftp_conn, $ftp_user, $ftp_pass);

// Change to the directory you want to download
ftp_chdir($ftp_conn, '/path/to/remote/folder/');

// Get the list of files and folders
$files = ftp_nlist($ftp_conn, '.');

// Download each file
foreach ($files as $file) {
    ftp_get($ftp_conn, $local_dir . basename($file), $file, FTP_BINARY);
}

// Close FTP connection
ftp_close($ftp_conn);
?>
