How can PHP.ini settings be adjusted to display errors and aid in debugging PHP Fusion websites?

To display errors and aid in debugging PHP Fusion websites, you can adjust the settings in the PHP.ini file. You can set the error_reporting directive to E_ALL to display all types of errors, and also set display_errors to On to show errors directly on the webpage. Additionally, you can enable the log_errors directive to log errors to a file for further analysis.

error_reporting(E_ALL);
ini_set('display_errors', 1);
ini_set('log_errors', 1);
