PHP Version Checker Online

Just paste the domain into our online PHP checker and run the scan. The tool looks for public server signals that may reveal the PHP version a website is using. It is the fastest way to get a best-effort public PHP version check without logging into hosting, cPanel, or WordPress.

You can try checking any website, but not every site exposes enough public information for PHP version detection. Some websites intentionally hide those details through server settings, security layers, CDNs, or reverse proxies. That means the tool can often detect a version, but not always. When a website keeps its server details hidden, the result may come back as not detectable.

Usually, that means the website is configured to hide PHP version details from public view. In some cases, it can also happen because the site is behind a CDN, proxy, security layer, or a setup that strips server headers. It can also mean the site is not running PHP at all. So "Not detectable" does not automatically mean there is a problem. It usually just means the version is not publicly visible.

When the tool finds a PHP version with strong public evidence, the result is usually accurate. But it is still a public detection method, not a direct server login or hosting-panel check. That means you should treat the result as best public detection, not as an absolute guarantee in every setup. If you own the site, checking from inside WordPress or hosting is always the most reliable method.

If you want to check a WordPress website from the outside, this tool is a quick first step. It can detect the PHP version when the site exposes enough public signals. If you own the WordPress site, the more reliable method is to open Dashboard → Tools → Site Health → Info → Server. That will show the actual PHP version directly inside WordPress.

Right now, the latest PHP version is PHP 8.5. If you are reviewing your stack, that makes it a strong reference point for what "current" looks like. Newer supported PHP versions usually give you better performance, better security, and stronger long-term compatibility than older branches.

In most cases, the best choice is a currently supported PHP version that works cleanly with your CMS, theme, plugins, and hosting setup. For most modern WordPress sites, that means staying on a recent supported branch instead of lingering on older versions. Our top picks are PHP 8.5 and PHP 8.4 because they offer the best mix of performance, security, and future-readiness.

You should plan a PHP upgrade. Newer PHP versions usually improve security and performance, and they reduce the risk of compatibility issues building up over time. The safest path is to back up the site first, confirm plugin and theme compatibility, then test key functions after upgrading. If you want zero guesswork, our team can handle the PHP upgrade for you.

No. This tool only runs the PHP version check and returns the result. We do not store a list of checked domains and we do not collect personal data through the tool itself. That makes it a simple and privacy-friendly way to check a site's publicly detectable PHP version.
