Why Aren't My PHP Errors Displaying, Even with `display_errors` Enabled?

Troubleshooting Unseen PHP Errors

Despite enabling display_errors and setting error reporting to E_ALL, you may still encounter issues with PHP errors not being displayed in your browser. Here are additional troubleshooting steps:

DEV Environment

Ensure the following settings are included at the top of your script:

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

Verify that your php.ini (or php-fpm.conf) contains the following line:

display_errors = on

Alternatively, you can add the following to your .htaccess file:

php_flag display_errors 1

PROD Environment

In a production environment, it's recommended to disable display_errors and enable logging:

display_errors = off
log_errors = on

This will allow you to view errors in the error log. See "Where to find PHP error log" for more information.

AJAX Calls

If you are encountering issues with AJAX calls, you can inspect the response in the browser's DevTools (F12) under the Network tab. In a production environment, check the error log instead.
