Why Aren't My PHP Errors Showing Up, and How Can I Fix It?

How to Display PHP Errors

Despite setting display_errors and error_reporting in php.ini, PHP errors remain hidden. This article provides comprehensive solutions to rectify this issue.

DEV Environment

To display PHP errors in a development environment, use the following code at the beginning of your script:

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

If this does not display parse errors in the same file, or if PHP settings are overridden, modify php.ini (or php-fpm.conf) by adding:

display_errors = on

Alternatively, for Apache servers, you can include the following line in .htaccess:

php_flag display_errors 1

PROD Environment

In a production environment, error display should be disabled:

display_errors = off
log_errors = on

This ensures errors are logged instead of being displayed on the page.

AJAX Calls

For AJAX calls, open the Network tab in DevTools (F12) and initiate the request. Click on the request in the Network tab and select the Response tab to view the error output. In a production environment, check the error log for AJAX errors.
