What best practices should be followed when working with FTP directory information in PHP to ensure accurate and reliable results?

When working with FTP directory information in PHP, it is important to ensure accurate and reliable results by properly handling errors and checking for successful operations. One best practice is to use error handling functions to catch any potential issues that may arise during FTP operations. Additionally, it is recommended to check for the existence of directories or files before attempting to access or manipulate them to avoid errors. 

// Connect to FTP server
$ftp_server = 'ftp.example.com';
$ftp_user = 'username';
$ftp_pass = 'password';
$ftp_conn = ftp_connect($ftp_server);
$login = ftp_login($ftp_conn, $ftp_user, $ftp_pass);

// Check for successful connection
if ((!$ftp_conn) || (!$login)) {
    die('FTP connection failed');
}

// Get directory listing
$files = ftp_nlist($ftp_conn, '/path/to/directory');

// Check if directory exists
if (!$files) {
    die('Directory does not exist');
}

// Loop through files
foreach ($files as $file) {
    echo $file . "<br>";
}

// Close FTP connection
ftp_close($ftp_conn);
