“Revamp your WordPress skills with this foolproof guide to updating PHP in your localhost!”

If You’re a WordPress Developer, You May Need to Upgrade PHP in Your Localhost

As a WordPress developer, it’s essential to keep your site running at its peak performance. This often means upgrading your PHP version to match that of your live WordPress site. Since PHP is the programming language WordPress runs on, it’s crucial to ensure you have the same PHP version installed locally as the one running on the server hosting your WordPress site. In this article, we’ll explore how to update PHP in WordPress localhost, step-by-step.

Step 1: Identify Your Current PHP Version

The first step is to check which PHP version you have running on your localhost. You can determine your PHP version through your WordPress dashboard, or by creating a PHP script. To check your PHP version via your WordPress dashboard, go to “Tools,” then select “Site Health,” and you’ll find your PHP version in the “Info” tab on top. Alternatively, create a PHP script following these steps:

  1. Create a new file named phpinfo.php in the root directory of your WordPress site.
  2. Add the following line of code to the file: <?php phpinfo(); ?>
  3. Access the file through your web browser by visiting http://localhost/phpinfo.php.

Your browser will display your current PHP version on the resulting page.

Step 2: Backup Your WordPress Site Locally

Before upgrading PHP, it’s crucial to take a full backup of your local WordPress site. With a complete backup, you can easily restore your site to its previous state if anything goes wrong during the upgrade. In case you want to think beyond traditional methods, you can look into Archive Document Storage services for a safe and more secure backup.

There are multiple plugins available on WordPress to help you backup your site, like UpdraftPlus, All-in-One WP Migration, etc. Choose the plugin that best suits your requirements to create a complete backup of your website.

Step 3: Upgrade Your PHP Version

Once completed with the backup process, you can upgrade your PHP version knowing your site is now safe. The process for upgrading PHP varies based on your operating system. Below is a step-by-step guide for three of the most commonly used operating systems:
