Detecting nothing is normal.
Well-configured sites hide those headers. It does not mean they are not running PHP.
PHP, WordPress and Drupal check
Is your site still getting security patches?
Enter your website address. We check what any visitor can see and tell you whether the PHP, WordPress or Drupal versions it exposes are still supported, and whether any is covered by a critical security advisory.
Confirm you are not a robot to keep checking.
What the result means
A visible version does not tell you whether it is patched.
Many providers apply security fixes without changing the version number. It is a lead to verify, not a diagnosis.
We only look at what is public.
No sign-in, no code execution, no admin paths. Exactly what any visitor would see.
