Here's the process: 1. **Paste a URL**, enter any website address. The tool automatically normalizes it and tries both root and common paths. 2. **Server scan**, the checker inspects HTTP response headers (like `X-Powered-By` and `Server`) for PHP version signatures. 3. **Result**, if the server exposes PHP info, you get the detected version with a confidence level. If the site hides its stack, you'll see "Not detectable." No login, no hosting access, no WordPress dashboard needed. Just a URL and a few seconds. ## Why Check Your PHP Version? PHP is the engine behind most of the web, WordPress, WooCommerce, Drupal, Laravel, and millions of custom sites all run on it. But unlike a car dashboard, most websites don't show you what version is under the hood. That matters because outdated PHP versions stop receiving security patches. Once a version hits end-of-life, every newly discovered vulnerability stays permanently unfixed. Your site keeps running, but the lock on the door is broken and nobody's coming to fix it. Run a [security headers check](https://webaloha.co/tools/security-headers-checker/) alongside this to get a full picture of your server's security posture. Performance is the other side. PHP 8.4 and 8.5 are significantly faster than older branches, we're talking [up to 33% more requests per second](https://webaloha.co/wordpress-php-8-5-compatibility/) in real WordPress benchmarks. That translates to faster page loads, better Core Web Vitals, and happier visitors. Use our [performance checker](https://webaloha.co/tools/website-performance-checker/) to measure the impact. If you're running a WordPress site, we've written detailed guides on [which PHP version to use](https://webaloha.co/recommended-php-version-for-wordpress/) and [which PHP extensions WordPress needs](https://webaloha.co/php-extensions-for-wordpress/). You can also check which [WordPress version a site is running](https://webaloha.co/tools/wordpress-version-checker/), use the [WordPress Theme & Plugin Detector](https://webaloha.co/tools/wordpress-theme-and-plugin-detector/) to see the full stack a site is running, or check any site's [full technology stack](https://webaloha.co/tools/website-technology-checker/) to see what's under the hood. Setting up or hardening a WordPress install? Our [wp-config.php generator](https://webaloha.co/tools/wp-config-generator/) builds a secure configuration baseline, and the [WP REST API exposure checker](https://webaloha.co/tools/wp-rest-api-exposure-checker/) flags whether your site is leaking user data through the REST API. Tired of chasing PHP versions altogether? A static [Astro website](https://webaloha.co/astro-website-design-development/) has no PHP, no plugins, and no database to maintain, just clean HTML that loads in under a second and is easy for AI engines to cite. If you're on WordPress, our [WordPress to Astro migration services](https://webaloha.co/wordpress-to-astro-migration-services/) rebuild your site without losing your rankings. ## PHP Version Support Timeline Not sure if your PHP version is still supported? Here's the current lifecycle for every PHP branch from 8.0 to 8.5, including active support dates, security-only windows, and known CVE counts. | Version | Status | Active support ends | Security fixes until | Known CVEs | | --- | --- | --- | --- | --- | | **PHP 8.0** | EOL | Nov 2023 | Nov 2023 | 24+ | | **PHP 8.1** | EOL | Nov 2024 | Dec 2025 | 9 | | **PHP 8.2** | Security only | Dec 2024 | Dec 2026 | 4 | | **PHP 8.3** | Active | Nov 2026 | Dec 2027 | 2 | | **PHP 8.4** | Active | Nov 2027 | Dec 2028 | 0 | | **PHP 8.5**latest | Active | Nov 2028 | Dec 2029 | 0\* | CVE counts from php.net security advisories and NVD. EOL versions receive zero patches, any newly discovered exploit is permanently unfixed. \*PHP 8.5.0 had 3 CVEs (CVSS 6.5); all patched in 8.5.1. Current release: 8.5.4. If your site is on anything below PHP 8.2, it's time to move.

It first looks for a PHP version in X-Powered-By, which is marked high confidence. A PHP token in Server is medium confidence, and a PHP/version string in the first 512 KB of a GET response body is low confidence. Why does the result say Not detectable? Most production sites hide runtime versions, and a CDN, proxy, cache, or security layer can strip them. The site may also use a different runtime. Not detectable means no supported public signal was found, not that PHP is missing or unsafe. What do confidence and evidence mean? Confidence describes the source of the detected string, and Evidence shows the public header or body signal. It is not a probability and does not prove which PHP binary handled every request behind a load balancer. Can a detected version be stale or misleading? Yes. A proxy can expose an old header, a cached page can contain a version string, and body text can mention PHP without identifying the runtime. Treat medium and low confidence as leads, and verify high confidence when making an upgrade decision. How should I verify the version on a site I own? Use the hosting control panel, command line php -v for the relevant environment, or WordPress Site Health under Tools, Site Health, Info, Server. Confirm production and staging separately because web and CLI runtimes can differ. What should I do if the verified version is unsupported? Back up the site, clone or use staging, check CMS, theme, plugin, extension, and custom-code compatibility, then upgrade and test critical pages, forms, checkout, jobs, and integrations. Keep a documented rollback path. Why might a repeated check show a cached result? Results are cached in server memory for 10 minutes by normalized URL, and the response indicates whether it was cached. Serverless instances may not share that memory, so caching behavior can vary. Wait or verify directly when testing a recent server change. What data is sent and retained by this checker? The submitted public URL is sent to Web Aloha's server, which may try HTTP, HTTPS, www, and non-www variants with HEAD and GET requests. The normalized URL and result can remain in an in-memory cache for up to 10 minutes; the endpoint does not store page bodies in a database.
