How can the display_errors setting in the php.ini file impact the output of exceptions in PHP scripts?

Setting the display_errors directive to On in the php.ini file will cause PHP to display error messages, including exceptions, directly on the screen. This can be useful for debugging during development but can also expose sensitive information to potential attackers in a production environment. To prevent this, it is recommended to set display_errors to Off and log errors to a file instead.

// Set display_errors to Off in php.ini file
ini_set('display_errors', 0);
// Log errors to a file
ini_set('log_errors', 1);
ini_set('error_log', '/path/to/error.log');
