So Why Should You Update PHP?

Updating your PHP version is crucial for maintaining a high-performing and secure website. Here are the main reasons why you should consider updating your PHP version:

  • New Features: Major PHP updates introduce features like new type declarations, improved functionality, and other features. Staying current allows you to benefit from these enhancements.
  • WordPress Plugin Development: When you opt to Custom WordPress development services to develop a custom plugin for your site, WordPress plugin developers make sure your developed plugin works with the latest PHP version.
  • Compatibility and Support: Running your site on the latest PHP version ensures compatibility with WordPress, themes, and plugins. Plus, hosting providers recommend using the recommended PHP version for optimal performance.
  • Better Debugging: Newer PHP versions provide improved error messages and warnings. This makes it easier to identify issues in your code. This helps developers pinpoint the exact problem area and fix it more efficiently.

How to Upgrade WordPress PHP Version

In the previous steps we saw how you can check php version through multiple ways. So, now we will see how you can upgrade your PHP version. What steps do you need to follow?

    Or what you can do is set up a staging environment and test the WordPress PHP upgrade on the site’s clone. This way your site will remain safe incase of any issues.
  2. Check Compatibility: Next, ensure that your plugins and custom code are compatible with the targeted PHP version. Some older plugins may not work correctly with newer PHP releases. Make sure to update or replace any incompatible components to avoid potential issues.
  3. Review Custom Code: Examine any custom PHP code you’ve written for your website. Make sure it follows the best practices and is compatible with the target PHP version. Make necessary adjustments to the code segments that might cause issues.
  4. Update WordPress and Plugins: Make sure your WordPress core ,plugins and themes are up to date. WordPress developers usually release updates to improve compatibility with newer PHP versions. To reduce conflicts, it is important to keep everything updated.
  5. Test Locally: Now, upgrade your PHP version. Visit the official PHP site and explore the PHP version you want to download. Once you do it, test your website to see how its performing.
    You can set up a local development environment. Use tools like XAMPP or Docker to test your website with the upgraded PHP version. This allows you to pinpoint and rectify any compatibility or performance issues prior to implementing the changes on your live site.
  6. Update Dependencies: Other than WordPress plugins and themes, check if your server-side dependencies such as database drivers, caching systems, and libraries are compatible with the new PHP version. You’ll need to update or replace them to maintain smooth functionality.
  7. Monitor Performance: After upgrading your PHP version, keep an eye on your website’s performance. This is important to note. Check for any unexpected errors, slow loading times, or memory usage spikes. Adjust settings or optimize code as needed.
