How can PHP be configured to display errors in the source code?

To display errors in the source code, you can configure PHP to show error messages directly in the browser by setting the `display_errors` directive to `On` in the php.ini file or using the `ini_set` function in your PHP script. This can be helpful for debugging and identifying issues in your code.

// Set display_errors directive to On in php.ini file
display_errors = On;

// OR use ini_set function in your PHP script
ini_set('display_errors', 1);
