Have you ever come across a message about your website’s PHP version on your WordPress Dashboard and thought… what on earth is that? — you’re not alone.
Did you know that:
👉 It’s one of the most important parts of your website.
And if it’s not up to date, it can cause problems behind the scenes.
It’s the code that runs on your server and builds your website pages.
Every time someone visits your website, PHP is working in the background to:
- Pull your content from the database
- Run WordPress and your plugins
- Process forms and user actions
- Generate the page your visitor sees
All in a fraction of a second.
What Does PHP Stand For?
PHP originally stood for “Personal Home Page”.
These days, it’s officially known as a recursive acronym:
👉 “PHP: Hypertext Preprocessor”
(Yes… slightly confusing—but don’t worry, the name matters far less than what it actually does!)
It’s Essential for WordPress Websites
If your website is built on WordPress (like most of the sites I work on), PHP is absolutely essential.
It’s what allows your site to be dynamic, meaning you can:
- Update your content easily
- Add blog posts
- Receive enquiries
- Sell products
- Manage memberships
Without PHP, your website simply wouldn’t function.
What Happens if PHP is Outdated?
This is where things can start to go wrong…
If your site is running an outdated version:
- ❌ It becomes less secure
- ❌ It can slow down
- ❌ Plugins and themes may stop working properly
- ❌ You increase the risk of errors or even site crashes
Many older websites are still running PHP 7.4, which is now end-of-life—meaning it no longer receives security updates.
Why Keeping PHP Updated Matters
Updating PHP is one of the simplest ways to improve your website’s:
- ✔ Speed
- ✔ Security
- ✔ Stability
- ✔ Compatibility with modern plugins
It’s not something your visitors will ever see…
but it has a big impact on how your website performs.
A Real Example (From a Recent Client Migration)
When I recently migrated a client website for Angela’s Aerobics, the site was running on an outdated PHP version.
On the surface, everything looked fine…
But behind the scenes, it meant:
- Increased security risk
- Reduced performance
- Potential compatibility issues
As part of the migration, I upgraded the site to PHP 8.4—bringing it up to date and ensuring it runs smoothly going forward.
What Version Should You Be Using?
Right now, the recommended version for most live websites is:
👉 PHP 8.4
It offers the best balance of:
- Stability
- Performance
- Compatibility
How to Check Your PHP Version
If you’re curious, you can usually check your PHP version in:
- Your hosting control panel
- Your WordPress dashboard (Tools → Site Health)
If you’re unsure, it’s always worth asking your web designer or hosting provider.
Final Thoughts
PHP might not be something you think about…
But it plays a crucial role in keeping your website running properly.
Keeping it updated is one of those small, behind-the-scenes tasks that makes a big difference to your website’s health.
