Why Aren't My PHP Errors Displaying in My Browser?

Troubleshooting PHP Error Display Issues

When PHP scripts encounter errors, it's crucial to be able to view these errors for quick resolution. Despite enabling display_errors and setting error reporting to E_ALL, errors may still not appear in browser output.

Steps to Ensure Error Display:

1. Verify PHP.ini Settings:
   Confirm that error reporting is enabled by setting error_reporting(E_ALL) and display_errors to 1 in php.ini.
2. Restart Web Server:
   Restart the Apache webserver to apply the changes made in PHP.ini.

3. Add Display Error Code:
   Include the following code at the beginning of the problematic PHP script:

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

Additional Considerations:

• Parse Errors:
  For parse errors that occur in the same file, modify the php.ini file with display_errors = on.
• Overriding of Settings:
  PHP settings can be overridden by the script itself. In such cases, modify php.ini or php-fpm.conf instead.
• htaccess Override:
  If you cannot access php.ini, consider adding php_flag display_errors 1 to the .htaccess file.

Production Environment:

In production environments, it's recommended to disable error display for security reasons:

display_errors = off
log_errors = on

AJAX Call Errors:

• Development Server:
  Check the Response tab in the Network tab of DevTools for the AJAX response containing the error.
• Production Server:
  Inspect the error log for details.
