What are some common pitfalls when trying to connect to an FTP server using PHP?

Common pitfalls when trying to connect to an FTP server using PHP include incorrect credentials, passive mode not being set correctly, and firewall issues blocking the connection. To solve these issues, make sure you are using the correct username and password, set passive mode to true, and ensure that the firewall allows connections to the FTP server. 

$ftp_server = 'ftp.example.com';
$ftp_username = 'your_username';
$ftp_password = 'your_password';

$ftp_conn = ftp_connect($ftp_server);
if (!$ftp_conn) {
    die('Could not connect to FTP server');
}

$login = ftp_login($ftp_conn, $ftp_username, $ftp_password);
if (!$login) {
    die('Could not login to FTP server');
}

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

// Now you can perform FTP operations here

ftp_close($ftp_conn); // Close the FTP connection
