What are some best practices for handling FTP server status checks in PHP to improve efficiency and accuracy?

Issue: When handling FTP server status checks in PHP, it is important to ensure efficiency and accuracy to prevent unnecessary delays or errors in the process. One way to improve this is by using built-in PHP functions specifically designed for FTP operations, such as ftp_connect and ftp_login, and implementing proper error handling to catch any potential issues. Code snippet: 

// FTP server status check
$ftp_server = 'ftp.example.com';
$ftp_user = 'username';
$ftp_pass = 'password';

// Connect to FTP server
$conn_id = ftp_connect($ftp_server);

if (!$conn_id) {
    die('Unable to connect to FTP server');
}

// Login to FTP server
$login_result = ftp_login($conn_id, $ftp_user, $ftp_pass);

if (!$login_result) {
    die('Unable to login to FTP server');
}

// Check if FTP server is online
if (ftp_pwd($conn_id) !== false) {
    echo 'FTP server is online';
} else {
    echo 'FTP server is offline';
}

// Close FTP connection
ftp_close($conn_id);
