Are there specific settings in php.ini that need to be adjusted to ensure error messages are shown in PHP?

To ensure error messages are shown in PHP, you need to adjust the settings in the php.ini file. Specifically, you should set the "display_errors" directive to "On" and the "error_reporting" directive to a level that includes all types of errors you want to see. This will allow PHP to display error messages on the screen, making it easier to debug and troubleshoot issues.

// Adjust settings in php.ini to show error messages
ini_set('display_errors', 1);
ini_set('error_reporting', E_ALL);
