Verifying PHP compatibility and WordPress versions

Checking PHP compatibility for the version of WordPress you are using is extremely important and necessary. As you know, each major version of PHP provides you with new functions and syntax, as well as removing old and obsolete elements. Therefore, you need to make sure that the PHP version works in harmony with the pre-installed WordPress core, plugins, and themes. Otherwise, your website may experience unexpected problems. Let’s have a look at PHP compatibility and WordPress version information here.

Ensuring the WordPress Core, Theme & Plugins are updated

An up-to-date WordPress site will stay safer, more efficient, and more accurate than a website that isn’t regularly updated. In addition, by updating this WordPress website, you may experience fewer incompatibilities or related problems during PHP updates. Therefore, you should update WordPress core, all active themes, and plugins before you update PHP in WordPress.

Backupping your WordPress site

In addition, you should back up your website in case of unfortunate incidents. You can use WordPress Backup Plugins to make the backup process become easier and faster.

Generating a Staging environment to test the PHP updating version

A WordPress staging environment is ideal for you to create a live copy of your website as well as store it in a private development area. This helps you safely make WordPress changes or updates. A Staging Environment is an effective solution to test a new PHP version without worrying about crashes. You can create a staging environment via your hosting company or use a WordPress plugin to do that.

After generating a staging environment that is the same as your live WordPress website, you will update PHP in this environment to ensure that everything works well. If all factors are nice, it’s time for you to update PHP in WordPress live website.
