What are some common reasons for FTP connection issues in PHP scripts?

Common reasons for FTP connection issues in PHP scripts include incorrect server credentials, firewall restrictions blocking the connection, or passive mode not being properly configured. To solve these issues, double-check the FTP server credentials, ensure the correct ports are open on the server's firewall, and set passive mode in the FTP connection. 

// FTP connection settings
$ftp_server = 'ftp.example.com';
$ftp_username = 'username';
$ftp_password = 'password';
$ftp_port = 21;

// Connect to FTP server
$conn_id = ftp_connect($ftp_server, $ftp_port);
if (!$conn_id) {
    die('Failed to connect to FTP server');
}

// Login to FTP server
$login_result = ftp_login($conn_id, $ftp_username, $ftp_password);
if (!$login_result) {
    die('Failed to login to FTP server');
}

// Set passive mode
ftp_pasv($conn_id, true);

// Proceed with FTP operations
// ...

// Close FTP connection
ftp_close($conn_id);
