How can the error reporting and display errors settings in the php.ini file affect PHP error messages?

The error reporting and display errors settings in the php.ini file control how PHP error messages are displayed. If error reporting is set to display errors, PHP errors will be shown directly on the webpage, potentially exposing sensitive information to users. To prevent this, it's recommended to set error reporting to "E_ALL & ~E_NOTICE" and display errors to "Off" in the php.ini file.

// Set error reporting level to show all errors except notices
error_reporting(E_ALL & ~E_NOTICE);

// Turn off display errors
ini_set('display_errors', 0);
