What are some potential security risks associated with publicly sharing secret codes in PHP scripts, as seen in the forum thread?

Sharing secret codes in PHP scripts publicly can pose a significant security risk as it exposes sensitive information that can be used by malicious actors to gain unauthorized access to systems or data. To mitigate this risk, it is recommended to store secret codes in environment variables or configuration files that are not publicly accessible.

// Store secret code in environment variable
$secret_code = getenv('SECRET_CODE');
