What does the PHP Version Checker check?

The PHP version your server reveals publicly

End of life: does the version still get security updates?

Warning when support for your version is about to end

Web server software and hosting provider

WordPress version and its update status

Minimum PHP version required by the detected plugins

How the PHP version check works

From URL to PHP version and support status in 4 steps

  1. 1 Step 1

    Enter URL

    Enter the address of the website. No server access, no plugin and no registration needed.

  2. 2 Step 2

    Read server headers

    We request the page and evaluate the response headers X-Powered-By and Server.

  3. 3 Step 3

    Compare with support periods

    The detected version is rated: current, support ending soon or end of life.

  4. 4 Step 4

    Plan the update

    Check the PHP requirements of your plugins in the report and switch the version in your hosting panel.

PHP versions and their support status

This is how the report rates the detected PHP version

Version Security updates until Status What it means
PHP 7.4 2022 End of life The last version of the PHP 7 series. Still found on many older websites, but without security fixes for years. Update urgently.
PHP 8.0 2023 End of life The first PHP 8 version. No longer maintained. A switch to a current 8.x version is usually unproblematic.
PHP 8.1 2025 End of life No longer receives security updates. Many plugins still support it, but you should not wait any longer.
PHP 8.2 2026 Support ending Only receives security fixes, and only for a short time. Plan the switch to 8.3 or 8.4 now.
PHP 8.3 2027 Supported A safe choice with broad plugin compatibility and security updates for the foreseeable future.
PHP 8.4 2028 Supported The version with the longest remaining support in this list. Before switching, check that all plugins are compatible.

All versions older than PHP 7.4 have reached their end of life and are rated as critical in the report. Newer versions that are not yet in this list are rated as supported.

Where the PHP version comes from

A check from the outside only sees what the server reveals

X-Powered-By header
The most common source. PHP adds this header itself, for example X-Powered-By: PHP/8.3.6, unless the setting expose_php is switched off.
Server header
Some web servers list their modules in the Server header, for example Apache/2.4 PHP/8.2.12. If X-Powered-By is missing, we evaluate this header.
Version hidden
If neither header names PHP, the version cannot be determined from the outside. The report then shows no PHP version. That says nothing about how up to date your version is.
Looking it up yourself
In WordPress the version is listed under Tools › Site Health › Info › Server. Alternatively, your hosting panel shows it, usually where you can also change it.
PHP Version Checker: check the PHP version of a website

Check the PHP version of a website without server access

Which PHP version a website runs on is normally something you look up in the hosting panel. The InspectWP PHP Version Checker gets it from the outside: we request your page and read the response headers of the server. Many servers state their PHP version there, in the X-Powered-By header or in the Server header. We read the version and tell you straight away whether it still receives security updates, whether support is about to end or whether it has already reached its end of life.

Why an outdated PHP version is a problem

Every PHP version is maintained for a limited time. After that, security holes are no longer fixed, no matter how serious they are. An outdated version is therefore a risk even if WordPress and all plugins are up to date. It also costs performance, because newer PHP versions process the same code noticeably faster. And it increasingly causes compatibility problems: plugins raise their minimum requirements, and at some point updates can no longer be installed. The report shows the PHP version each detected plugin requires, so you can see before an upgrade whether your setup is ready.

Frequently asked questions about the PHP Version Checker

How detection works, where its limits are and how to update

InspectWP requests your page and evaluates the HTTP response headers. If the server sends an X-Powered-By header such as PHP/8.2.12, or names PHP in the Server header, we read the version from it and compare it with the official support periods.
