About PHP Version Checker

A large share of the web still runs on PHP versions that no longer get security patches. Site owners often don’t know which version their host uses, and agencies, developers and security reviewers need a quick way to check many sites without logging in to each server.

This tool answers that in a few seconds, without sign-up, and is honest about how sure it is. See the checker on the home page for how the detection and confidence levels work.

• Public information only. We load the page once, like a browser does (following redirects), and read what the site already sends to every visitor: HTTP headers, cookies and HTML.
• No scanning. We don’t probe ports, guess URLs, log in or try to exploit anything.
• Evidence, not guesses. Every result lists the signals that were found, so you can verify the answer yourself.
• Private networks are off limits. Requests to localhost, private IP ranges and cloud metadata addresses are refused.

Release, active-support and end-of-life dates come from the official PHP project: php.net supported versions and the unsupported branches list. The PHP versions table is updated when a new PHP version is released, usually in late November.

Many servers hide their PHP version on purpose, for example with expose_php = Off or by stripping headers at a CDN. In that case we can often tell that a site runs PHP, but not the exact version. Only someone with server access can always see it, using php -v or phpinfo().
