What are the potential risks of leaving debugging lines in PHP code and how can they be mitigated?

Leaving debugging lines in PHP code can expose sensitive information about the application, such as database credentials or internal logic. This can be a security risk if the code is deployed to a production environment. To mitigate this risk, all debugging lines should be removed before deploying the code. 

// Before deploying to production, remove all debugging lines
// For example, remove any var_dump(), print_r(), or echo statements

// Debugging line to be removed
var_dump($someVariable);
