How can PHP error messages from directly accessed scripts pose security threats?

Directly accessing PHP scripts can expose error messages that may reveal sensitive information about the server configuration, file paths, or database structure, which can be exploited by attackers. To prevent this, error messages should be disabled or logged to a secure location instead of being displayed to users. 

// Disable error messages from being displayed to users
ini_set('display_errors', 0);
ini_set('display_startup_errors', 0);

// Log errors to a file instead
ini_set('log_errors', 1);
ini_set('error_log', '/path/to/error.log');
