4. Make sure your WordPress site has the latest version of PHP

Once you’ve made a backup and checked to see if there are any changes for WordPress, you can move on to upgrading the Latest PHP version. Make sure it works with the version of WordPress you’re using now.

The best way to update PHP in WordPress:

If this is the first time you’ve updated PHP versions in WordPress, we suggest doing the following:

Check to see if your theme and plugins are compatible with PHP

Some themes or plugins might not work with the current version of PHP or certain older versions. It’s important to make sure that your site’s style and plugins are compatible with the update so that it will still work after the update.

Go to the loaded Plugins page and click View details next to each loaded plugin to see which PHP versions it supports. Under Requires PHP Version, a pop-up window will show the suggested PHP settings.

Visit the WordPress theme directory to see if a theme works with your PHP version. Use the search bar to find your WordPress theme, and then pick “More Info.” In the PHP Version part, you can find out what you need to do.

Update PHP on a staging site to see how it works

If you check PHP support, you probably won’t have any problems. But it is better to try the Latest PHP version in a WordPress staging environment to make sure the website will work correctly.

A staging setting for WordPress lets you test and change themes, plugins, and new versions of PHP without affecting the live site.

During the testing process, if you don’t find any problems, you can safely update the PHP version of the live site.

Check your site regularly for issues

After you update PHP, you should definitely keep an eye on your website. Check for broken links, redirected error pages, plugins that don’t work well together, and site speed problems.

Using a WordPress analytics tool like MonsterInsights or WP Statistics is a simple way to keep an eye on your site. These plugins have strong tools and features that can help you track traffic, page views, and site speed, as well as gather, analyze, and track this information.

But if you want to fix any possible mistakes, you might want to look at the PHP error log. To do that, you need to use your server control panel to turn on PHP error logging.

Once the problem has been fixed, we suggest turning off the PHP error log so it doesn’t take up too much room.

If you still have problems after studying how well the site works and keeping an eye on the PHP error log, switch the site back to an older version of PHP. The steps are the same as when you update PHP; all you have to do is choose the older version.

Contact your hosting company’s customer service

Before updating the PHP version of your WordPress installation, contacting the customer support team of your hosting company is an additional precaution you may take. Those who have no prior experience with the activity at hand may benefit greatly from this in particular.


Since PHP is the core language of WordPress, themes and plugins also use it. Updating the WordPress PHP version has many benefits for your website, such as making it run faster and making it safer.

We’ve also talked about the best ways to update the PHP version for WordPress. For example, you should test the new version of PHP on a development site, keep an eye on your website for problems, and make sure your themes and plugins are compatible.
