Why Change It

Think of PHP as the heart of your WordPress site, pumping life into every part of it. Just like any software, PHP gets better over time. New versions come out that make your site run faster, safer, and more in tune with the latest web technologies.

Here’s why updating your PHP version is a smart move:

  1. Speed up your site: The newer PHP versions work faster. This means your pages load quicker, giving your visitors a better experience. Fast sites also rank better in search engines, helping more people find you.
  2. Enhance security and vulnerability protection: Changing to a newer PHP version enhances security by bringing in new security features, bug fixes, and enhancements that protect against potential vulnerabilities.
  3. Improve website performance: Upgrading PHP can significantly improve your website’s performance, making it faster and more efficient.
  4. Keep your site safe: With each update, PHP fixes bugs and patches security holes. Keeping your PHP version current helps protect your site from hackers looking to exploit old vulnerabilities.
  5. Stay compatible: WordPress and many plugins and themes need the latest PHP version to work. Updating ensures everything runs smoothly together, and you can use the newest and coolest features without a hitch.
  6. Reduce resource usage: Newer PHP versions are not just faster; they’re also more efficient. This means your site can do more with less server power, which is great for keeping hosting costs down and handling more visitors at the same time.
  7. Improve error handling: Each PHP update improves the way errors are handled and reported. This makes diagnosing and fixing any issues on your site much easier, saving you time and headaches.

Changing your PHP version is like giving your site a health check-up. It ensures your site stays fast, safe, and compatible with all the latest web algorithms. And with FlyWP, doing this update is easier than you might think. So give your site the boost it deserves!

What are the risks of not updating the PHP version?

Not updating the PHP version of your website poses several risks that can impact security, performance, compatibility, support, and access to new features. Apart from that, there are still some other risk factors if you don’t update the PHP version in time.

Let’s try to find out them:

  1. Compromised security: Running an outdated PHP version exposes your website to security risks, making it vulnerable to cyberattacks that can compromise sensitive data like personal information, login credentials, and financial data.
  2. Compatibility issues: Websites using older PHP versions may face compatibility issues with future software updates, plugins, themes, and other software. This can lead to a poor customer experience and penalties in terms of search engine optimization (SEO)
  3. Lack of support: As PHP versions reach their end-of-life, receiving support from the development community becomes challenging. Sticking with outdated PHP versions may require additional costs and custom development workarounds to maintain.
  4. Performance degradation: Outdated PHP versions can result in decreased performance, slower load times, and reduced efficiency. Upgrading to newer PHP versions can enhance performance by reducing server load.
  5. Limited access to new features: Not updating PHP restricts access to new features and improvements introduced in newer versions. 

What to consider before changing the PHP version (focus on 7 things)

Update Php Version

Changing or updating the PHP version seems like a simple task. But it can damage your entire site if not followed in the right way. Therefore, we have compiled a list of 7 most important factors to check before you update the PHP version of your WordPress site.

1. Check compatibility first: Make sure your WordPress theme and plugins will play nicely with the new PHP version. You can do this by checking their documentation or reaching out to the developers.

2. Back it up: Always back up your website before making changes like this. It’s your safety net. If something doesn’t go as planned, you can always restore your site to how it was before.

3. Test on a staging site: If you can, try out the new PHP version on a staging site first. A staging site is like a clone of your real site, where you can test changes without affecting your live site.

4. Keep an eye on performance: After you have updated, watch your site’s performance. Faster is always better, but just make sure everything is running smoothly and as expected.

5. Note down changes: Record what you’ve done, like which PHP version you switched to. This helps if you need to troubleshoot or talk to support later.

6. Update regularly: PHP isn’t the only thing that needs updating. Keep your WordPress core, themes, and plugins up to date too. This keeps everything working well together.

7. Have support ready: Know how to get in touch with your hosting provider or a tech-savvy friend in case you need help. It’s good to have backup!

Changing your PHP version is a big step towards a faster, safer site. By keeping these things in mind, you’ll be set for a smooth update. And FlyWP makes this whole process easier.
