How can PHP errors or bugs lead to the exposure of PHP source code to visitors, and how can this be prevented?

PHP errors or bugs can lead to the exposure of PHP source code to visitors if error messages containing code snippets are displayed on the webpage. To prevent this, error reporting should be turned off in the production environment to ensure that any errors are logged without displaying sensitive information to visitors. 

// Turn off error reporting in production environment
ini_set('display_errors', 0);
ini_set('display_startup_errors', 0);
error_reporting(0);
