What are common issues when trying to establish a connection to an FTP server using PHP?

Common issues when trying to establish a connection to an FTP server using PHP include incorrect credentials, firewall restrictions, or server configuration issues. To solve these problems, double-check the FTP server address, username, and password for accuracy, ensure that the server allows FTP connections from your IP address, and verify that the necessary PHP FTP extension is installed and enabled. 

$ftp_server = 'ftp.example.com';
$ftp_user = 'username';
$ftp_pass = 'password';

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

$login = ftp_login($conn_id, $ftp_user, $ftp_pass);
if (!$login) {
    die('Login failed');
}

// Continue with FTP operations
