PHP Version Checker
Check the PHP version of a website – free and online
Enter a domain and PHP Checker shows which PHP version the site publicly reveals, whether that version is still supported and whether the latest PHP vulnerabilities are patched.
Free, no sign-up, results in seconds.
What the PHP version checker looks at
- Public version hints: headers such as
X-Powered-Byand other signals a site sends. - Patch level: compared with the official php.net fixes (PHP 8.2.35, 8.3.36, 8.4.27, 8.5.12).
- Clear verdict: “Vulnerable”, “Not vulnerable” or “Still unclear” – with reasons.
- Instant help: a wizard walks you through updating PHP and re-checks afterwards.
When a site hides its PHP version
Well-configured servers often hide the PHP version. PHP Checker then offers two more options: enter the version yourself (e.g. from your hosting panel) or upload a small verification file that reports the exact version and proves you control the site.
Who is it for?
