What are the potential security risks of using PHP scripts to replicate files between two remote machines?

One potential security risk of using PHP scripts to replicate files between two remote machines is the possibility of exposing sensitive information, such as login credentials or file paths, in the code itself. To mitigate this risk, it is recommended to store sensitive information in environment variables or configuration files outside of the web root. 

// Example of securely storing sensitive information in environment variables
$remoteHost = getenv('REMOTE_HOST');
$remoteUser = getenv('REMOTE_USER');
$remotePass = getenv('REMOTE_PASS');

// Use the stored variables to establish a secure connection and transfer files
