How does error reporting impact the display of variables in PHP?

Error reporting in PHP can impact the display of variables by potentially revealing sensitive information to users if error messages contain variable values. To prevent this, it is recommended to set error reporting to a lower level in production environments to avoid displaying variable values in error messages. 

// Set error reporting to not display variable values in error messages
error_reporting(E_ALL & ~E_NOTICE);
