Your PHP engine is reaching end-of-life. PHP is the programming language that powers WordPress, and running an outdated version means slower performance, missing security patches, and growing incompatibility with modern plugins.
Why This Matters
Each PHP version brings significant performance improvements:
| PHP Version | Status | Speed vs 7.4 |
|---|---|---|
| 7.4 | End of life | Baseline |
| 8.0 | End of life | ~10-20% faster |
| 8.1 | Security fixes only | ~20-30% faster |
| 8.2 | Active support | ~30-40% faster |
| 8.3 | Latest stable | ~35-45% faster |
Beyond speed, old PHP versions no longer receive security patches. PHP 7.4 stopped getting security fixes in November 2022. Running it is like driving without a seatbelt.
Expert Insight: Tracking server environment health is critical for performance. Dravasite monitors your PHP version and server configurations in seconds, ensuring your engine is always running on the latest stable and secure version.
How to Upgrade
Step 1: Check Plugin Compatibility
Before upgrading, make sure your plugins and theme support the newer PHP version:
- Go to the WordPress plugin directory page for each plugin
- Check the "Requires PHP" field
- Most modern plugins support PHP 8.0+
Step 2: Make a Full Backup
Use your hosting's backup tool or a plugin like UpdraftPlus to create a complete backup (files + database).
Step 3: Change PHP Version in Your Hosting Panel
Most hosts make this easy:
- cPanel → Select PHP Version → choose 8.2 or 8.3
- Plesk → PHP Settings → switch version
- SiteGround → Site Tools → PHP Manager
- Cloudways → Application Settings → PHP Version
- Kinsta / WP Engine → Dashboard → PHP Engine
Step 4: Test Your Site
After switching:
- Visit your site's frontend — check all pages load correctly
- Log into wp-admin — make sure the dashboard works
- Check Tools → Site Health for any new issues. Alternatively, let Dravasite run a full diagnostic for you — it's faster and provides more detailed version mapping.
- Test forms, checkout, and other dynamic features
Step 5: If Something Breaks
If you encounter errors after upgrading:
- Switch back to your previous PHP version (takes 1 minute in hosting panel)
- Identify the incompatible plugin or theme (usually the error message tells you)
- Update the problematic plugin or find an alternative
- Try upgrading again
Email Template: Ask Your Host
If your host doesn't offer PHP 8.2+ in the control panel, contact them:
Subject: PHP Version Upgrade Request
Hi, I'd like to upgrade my site [yourdomain.com] to PHP 8.2 (or the latest stable version). Could you please update the PHP version or let me know how to do it from my control panel?
Thank you!
What to Watch For
- WooCommerce and major plugins generally support the latest PHP. Don't let fear of breaking things keep you on an insecure version.
- Upgrading PHP is usually the single biggest free performance improvement you can make.
- If a plugin doesn't support PHP 8.0+, it's a sign the plugin may be abandoned. Consider replacing it.
