Behind every high-performing WordPress website is an engine that powers it all: PHP. And like all good engines, it needs to be maintained and upgraded to keep up with modern demands.
Over the last three months, we rolled out PHP 8.2 across more than 150 websites hosted on our servers; making them faster, more secure, and more future-proof. Here’s what PHP does, why this upgrade was important (especially if your site runs on WordPress and Elementor), and what it means for our clients moving forward.
What Is PHP?
PHP (Hypertext Preprocessor) is the scripting language that powers around 75% of all websites, including every WordPress and Elementor site. It handles the logic behind forms, page templates, databases, and dynamic content. Without it, your site is just a collection of static files.
Why Outdated PHP Slows Things Down
Running an older PHP versions, like 7.4 or earlier can seriously hold your site back:
- Security risks: Older PHP versions are no longer supported and can’t be patched
- Performance bottlenecks: PHP 7.4 is significantly slower than modern versions
- Compatibility issues: Newer plugins, themes, and WordPress core features may break or glitch on outdated PHP
For sites built with Elementor, outdated PHP can mean:
- Glitchy editing tools
- Broken widgets
- Site crashes when updating or publishing content
The Difference PHP 8.2 Makes
After upgrading more than 150 sites, both our team and our clients immediately noticed a performance boost.
While we didn’t run benchmarks across every site, independent performance tests show that PHP 8.2 is:
- Up to 30–50% faster than PHP 7.4 in processing requests
- Capable of handling more simultaneous users with less server strain
- More efficient at executing code-heavy features used by WordPress plugins and page builders
So while we don’t have exact numbers for each site, the difference was clear: pages load faster, backend interfaces feel smoother, and sites run more efficiently across the board.
PHP Version Comparison
| PHP Version | Released | Status | Performance | Security |
| 7.4 | 2019 | End of Life | Slower | Unsupported |
| 8.0 | 2020 | Deprecated | Improved | Patched (for now) |
| 8.2 | 2022 | Active | Fastest | Fully Supported |
Our 3-Month Rollout: How We Did It Safely
Updating PHP on a WordPress site isn’t as simple as pushing a button. It involves careful planning to avoid breaking anything, especially when a site relies on multiple plugins and a custom theme.
Here’s how we handled it:
Staged Rollout Across Servers
We batched websites by hosting environments and updated each one in a controlled phase.
Full Stack Updates
We updated WordPress core, Plugins and Active themes after changing the PHP version. This ensured the entire stack was compatible and any conflicts were identified early in the process.
Backups & Manual Testing
Before each update, we created a full backup of the site. After the PHP upgrade, we did:
- A visual inspection to check design integrity
- A manual functionality check (forms, menus, integrations, checkout flows)
This reduced the risk of future issues as plugin and WordPress updates are released.
What This Means for Clients
- Immediate Performance Gains: Faster load times and smoother performance, especially on content-heavy or Elementor-based sites.
- Stronger Security: Up-to-date PHP means fewer vulnerabilities and better protection against exploits.
- Future-Proof Hosting: All our new websites are hosted on platforms that include automatic PHP version updates, ensuring they stay current without manual intervention.
- Ongoing Maintenance: Every site on our maintenance plans now runs on PHP 8.2 and will continue to be upgraded as new versions are released.
What Clients Are Saying
We’ve already had several clients comment that their websites feel snappier and load quicker. While not formal testimonials, it’s validation that the rollout has had real-world impact—and we’re seeing the same improvements internally.
FAQs
Q: How do I check my site’s PHP version?
If you’re hosted with us, we’ve already handled it. If not, ask your host or install a plugin like Display PHP Version.
Q: Can updating PHP break my site?
If done carelessly—yes. That’s why we updated plugins, themes, and WordPress core before upgrading PHP, and manually tested each site after.
Q: Do all Clickk sites now run PHP 8.2?
Yes. All hosted and maintained websites are now running PHP 8.2. New sites will automatically stay up to date thanks to our new hosting platform.
Final Thoughts
PHP might be behind the scenes, but it plays a front-line role in your website’s performance and stability. This update ensures our clients’ websites are not only running faster today—but are ready for what’s next.
