What are the best practices for handling FTP URLs in PHP when using functions like yaml_parse_url?

When working with FTP URLs in PHP and using functions like yaml_parse_url, it is important to properly handle the FTP credentials in the URL to ensure secure access to the FTP server. One common best practice is to extract the FTP credentials from the URL and pass them separately to the FTP functions, rather than including them directly in the URL string. This helps prevent sensitive information from being exposed in the URL. 

// Example of handling FTP URLs in PHP using yaml_parse_url
$url = "ftp://username:password@ftp.example.com/path/to/file.txt";

$parsed_url = parse_url($url);

$ftp_server = $parsed_url['host'];
$ftp_user = $parsed_url['user'];
$ftp_pass = $parsed_url['pass'];

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

// Additional FTP operations can be performed here

// Close FTP connection
ftp_close($ftp_conn);
