What are best practices for verifying the success of FTP operations in PHP before proceeding with additional steps?

When performing FTP operations in PHP, it is important to verify the success of each operation before proceeding with additional steps to ensure data integrity. One way to do this is by checking the return value of FTP functions for success or failure. This can be achieved by using conditional statements to handle different outcomes based on the result of the FTP operation. 

// Connect to FTP server
$ftp_server = 'ftp.example.com';
$ftp_username = 'username';
$ftp_password = 'password';
$conn_id = ftp_connect($ftp_server);
$login_result = ftp_login($conn_id, $ftp_username, $ftp_password);

// Check if connection and login were successful
if ($conn_id && $login_result) {
    // FTP operation was successful, proceed with additional steps
    echo 'FTP connection successful.';
    
    // Perform additional FTP operations here
    
    // Close FTP connection
    ftp_close($conn_id);
} else {
    // FTP operation failed, handle error
    echo 'FTP connection failed.';
}
