What potential pitfalls should be considered when using PHP to interact with FTP servers?

One potential pitfall when using PHP to interact with FTP servers is the lack of error handling, which can lead to unexpected behavior or security vulnerabilities. To mitigate this, it is important to implement proper error handling and validation in your PHP code to handle any potential issues that may arise during FTP interactions. 

// Connect to FTP server with error handling
$ftp_server = "ftp.example.com";
$ftp_user = "username";
$ftp_pass = "password";

$conn_id = ftp_connect($ftp_server) or die("Could not connect to $ftp_server");

// Login to FTP server with error handling
if (!ftp_login($conn_id, $ftp_user, $ftp_pass)) {
    die("Login failed");
}

// Close FTP connection with error handling
if (!ftp_close($conn_id)) {
    die("Failed to close FTP connection");
}
