Recommended PHP Version for WordPress in 2026

For properly maintained WordPress websites in 2026, the recommended PHP version is PHP 8.5.

Why? Because PHP 8.5 is the best choice for performance, security, and future-proofing. If your WordPress site is updated, your plugins are maintained, and you can test properly, PHP 8.5 is the recommended version for you.

And we’ve already done an extensive PHP 8.5 and WordPress compatibility test on over 50 real websites. We can confidently say – PHP 8.5 version is fully compatible with modern WordPress versions.

PHP 8.4 is a second best version for WordPress website, as well as safer fallback. PHP 8.4 version is also fast, secure, and actively maintained. Plus it has been around longer, which gave WordPress core, plugins, and themes more time to catch up. We’ve tested PHP 8.4 compatibility with WordPress as well. Long story short: works like a charm and been this way for over a year.

PHP 8.3 is a minimum recommended version for WordPress. In fact, we’ve used PHP 8.3 for years across dozens of WordPress websites. But in 2026, it’s no longer the version we’d recommend as the first choice. Because it is not actively maintained anymore, and as of 2026, is on security-only fixes cycle.

At Web Aloha we actively build and currently maintain over 50 WordPress websites, including WooCommerce stores. Since we work with PHP and WordPress daily, everything in this article comes from real testing on real production sites.

Let’s break down which PHP version is recommended for WordPress in 2026. We’ll discuss why PHP 8.5 is the best choice, when PHP 8.4 or older makes more sense, and how WooCommerce affects the decision.

Why PHP Version Matters for WordPress

A lot of WordPress site owners treat PHP as some invisible server detail they never need to think about.

That works right up until it doesn’t.

PHP is the engine under your WordPress site. It affects speed, security, compatibility, and how future-proof your website is. Not sure what’s under your hood? Our website technology checker can show you your current PHP version, CMS, server, and more. With a modern PHP version, your site gets a better foundation to run on and usually performs faster. When you stay on an outdated PHP version, you start losing the technical advantages your WordPress website could have.

Why a modern PHP version is better for a WordPress website:

• Gives a longer security and support runway
• Improves performance compared to older PHP versions
• Makes future plugin, theme, and WooCommerce updates easier
• Reduces the odds that you’ll be forced into a rushed upgrade later

PHP’s current support policy is simple: each PHP branch gets two years of active support and two more years of security patches. PHP 8.5 stays in active support until the end of 2027, and PHP 8.4 until the end of 2026.

That said, PHP 8.3 and older versions are already out of active support. That means they are no longer being adjusted to current best practices. If you want the best performance, you should not rely on them.

In real-world terms, that means any future PHP 8.5 or 8.4 update can widen the performance gap even further. And in 2026, you want every technical advantage you can get for your WordPress website.

That’s why the “best WordPress PHP version” question matters. You’re not just choosing what works best today. You’re future-proofing your website.

Why PHP 8.5 Version Is the Best for WordPress in 2026

PHP 8.5 gives your WordPress site the best mix of speed, security, and future-proofing. It is the newest stable branch, stays in active support until the end of 2027, and receives security fixes until the end of 2029. That gives WordPress site owners the longest support runway available today.

Performance is another big reason. In PHP 8.5 benchmarks, plain WordPress + WooCommerce setup showed a whopping 33% requests per second (req/s) increase over PHP 8.4. Those are the kind of improvements people can actually feel on real sites.

Our recommendation comes with one important condition: your WordPress site should be maintained properly. WordPress 6.9 labels PHP 8.5 as beta support because the ecosystem needs time to catch up before a version moves into full support.

That said, WordPress Core still encourages users to run the latest PHP versions, including PHP 8.5. In other words, PHP 8.5 is the recommended choice for modern WordPress sites, but you still need updated plugins, an updated theme, and proper testing before switching. Not sure what your full plugin and theme stack looks like? Our WordPress theme and plugin detector can help you audit that.

PHP 8.4 Version Is the Safe Fallback for WordPress

PHP 8.4 is the second-best PHP version for WordPress in 2026.

We’ve been using PHP 8.4 on 50+ WordPress websites for over a year, and it has worked very well. In fact, some websites still use it today across our WordPress stack.

PHP 8.4 is fast, secure, actively maintained in 2026, and it has been around long enough for WordPress core, plugins, and themes to catch up properly.

That matters more than you might think. If any of the plugins you rely on are not fully compatible with the latest PHP version yet, PHP 8.4 is the way to go. You still get great speed, strong security, and a modern PHP branch, with a little more ecosystem maturity behind it.

We recommend PHP 8.4 version if you’re not a professional developer like us and simply want a safe, reliable choice for your WordPress website.

PHP 8.3 Is the Minimum Recommended for WordPress

PHP 8.3 is the minimum version we recommend using for WordPress in 2026. It has been around for over two years, which means WordPress core, plugins, and themes have had plenty of time to adjust to it.

We used PHP 8.3 on many of our WordPress websites too, but that was around two years ago. In 2026, PHP 8.3 is no longer the best choice for WordPress.

It is already out of active support, which means it is no longer being improved by the official PHP development team. That gives you less future runway and fewer performance advantages than newer PHP versions. And the gap will only get bigger.

PHP 8.3 is still stable, widely compatible, and much safer than using anything older. PHP 8.3 is also the minimum PHP version officially recommended by WordPress. If you’re not sure what version your site is currently running, check with our PHP version checker.

Bottom line: if you can’t use newer versions, PHP 8.3 is fine. Or you can get in touch with Web Aloha to help you upgrade and go from fine to fantastic. 💪😏

Avoid Using PHP 8.2, 8.1, and Older on WordPress

We do not recommend using PHP 8.2, 8.1, or anything older on WordPress in 2026.

The main reason is support. PHP 8.2 has been out of active support for over a year now, and its security fixes end at the close of 2026. PHP 8.1 is another year behind. Sites on outdated PHP often have other neglected areas too, run a security headers check and SSL certificate check to see if your server config needs attention. Avoid using older PHP versions if you want your WordPress site to thrive in a digital jungle.

The world is moving forward. WordPress 7.0 is dropping support for PHP 7.2 and 7.3, while the minimum recommended PHP version remains 8.3. So even from the official docs we mentioned in the previous section, the direction is clear. Modern PHP is the right path for WordPress.

If you are not comfortable safely moving your WordPress site to a newer PHP version, drop us an Aloha. We’ve been working with WordPress for 8+ years and moved dozens of websites to newer PHP versions. We can help you upgrade properly, without turning your website into an experiment.

Recommended PHP Version for WooCommerce in 2026

For updated and well-maintained WooCommerce stores in 2026, the recommended PHP version is PHP 8.5. That opens the door to the best performance and security, which are critical for WooCommerce.

By the way, we’ve tested PHP 8.5 and WooCommerce compatibility on real websites ourselves. We tested different payment options, multilingual setups, custom fields, and more. Compatibility is great.

WooCommerce stores are generally much more demanding PHP-wise than standard WordPress websites. They deal with dynamic queries, payment gateways, stock updates, and a heavier plugin stack. All of that adds up fast, and it makes modern PHP even more important for WooCommerce.

In PHP 8.5 benchmarks, WooCommerce was the standout case: PHP 8.5 reached 71.02 requests per second, compared to 53.37 req/s on PHP 8.4, which is roughly a 33% increase. On a real WooCommerce store, those are the kind of gains visitors can actually feel. You can see where your store stands right now with our website performance checker.

The heavier the store, the more valuable an efficient PHP version becomes. This is why actively supported PHP 8.4 is the minimum we recommend for WooCommerce.

Keep in mind: WooCommerce stores should also be tested and prepared more thoroughly before upgrading the PHP version.

It is easier to break something important on a store than on a basic brochure website. If a checkout flow, shipping method, or product option stops working, that is real money leaking out of the business. Before and after upgrading, it’s a good idea to run a broken link check and verify your redirect chains are still clean.

So yes, PHP 8.5 is the recommended version for WooCommerce in 2026, but only after proper staging, compatibility checks, and real testing of the whole shopping flow.

Summary: PHP 8.5 is Recommended for WordPress

For properly maintained WordPress websites in 2026, PHP 8.5 is the recommended version. PHP 8.4 is the safer fallback, PHP 8.3 is the minimum, and PHP 8.2 or older should be avoided. Once you’ve upgraded, don’t stop there, check your meta tags and Open Graph tags to make sure your site looks right in search results and social shares.
