What are potential security risks when using FTP login credentials in PHP code?

Using FTP login credentials in PHP code can pose a security risk because the credentials are stored in plain text, making them vulnerable to being accessed by malicious actors. To mitigate this risk, it is recommended to store the credentials in a separate configuration file outside of the web root directory and include this file in your PHP scripts. 

//config.php
define('FTP_HOST', 'ftp.example.com');
define('FTP_USER', 'username');
define('FTP_PASS', 'password');

//ftp_script.php
require_once('config.php');

$ftp_conn = ftp_connect(FTP_HOST);
$login = ftp_login($ftp_conn, FTP_USER, FTP_PASS);

if(!$ftp_conn || !$login) {
    die('FTP login failed');
}

// continue with FTP operations
