What are the security implications of parsing error messages for data extraction in PHP applications?

Parsing error messages for data extraction in PHP applications can expose sensitive information about the application's inner workings to potential attackers. This information can be used to launch targeted attacks against the application, such as SQL injection or code injection attacks. To mitigate this risk, error messages should be logged and monitored internally, but not displayed to users in a production environment.

// Example of logging errors instead of displaying them to users
ini_set('display_errors', 0);
ini_set('log_errors', 1);
ini_set('error_log', '/path/to/error.log');
