What is the best practice for allowing FTP access to modify files uploaded via PHP?

When allowing FTP access to modify files uploaded via PHP, it is important to ensure that proper security measures are in place to prevent unauthorized access. One approach is to restrict FTP access to a specific directory where uploaded files are stored, and to use secure FTP credentials. Additionally, it is recommended to sanitize and validate file names before allowing them to be modified via FTP. 

// Example code snippet for allowing FTP access to modify files uploaded via PHP

$ftp_server = "ftp.example.com";
$ftp_username = "username";
$ftp_password = "password";
$ftp_directory = "/path/to/uploaded/files/";

// Connect to FTP server
$ftp_conn = ftp_connect($ftp_server);
$login = ftp_login($ftp_conn, $ftp_username, $ftp_password);

// Change directory to the upload directory
ftp_chdir($ftp_conn, $ftp_directory);

// Perform FTP actions such as uploading, downloading, or deleting files
// Make sure to validate and sanitize file names before allowing modifications

// Close FTP connection
ftp_close($ftp_conn);
