Introduction

Keeping your WordPress site up to date is crucial for ensuring its performance, security, and compatibility with the latest features and plugins. One essential aspect of maintaining a WordPress site is updating the PHP version. PHP, a server-side scripting language, powers your WordPress site and influences its speed and functionality. In this comprehensive guide, we’ll explore how to update PHP on WordPress, the benefits of updating it, and various tips to undertake this process smoothly. So, let’s dive in!

Understanding What PHP Is

Before we discuss how to update PHP on WordPress, it’s essential to grasp what PHP is and why it matters. PHP—Hypertext Preprocessor—is the backbone of many web applications, including WordPress. It executes scripts that generate dynamic website content and communicates with databases. A newer PHP version can enhance performance, improve security, and ensure compatibility with modern functionalities.

Why You Should Update PHP

Updating the PHP version on your WordPress site is not merely a technical necessity; it comes with several benefits:

• Performance Improvements: Each new PHP version is optimized for better speed, which can significantly enhance page load times.
• Security Enhancements: Older PHP versions may have unpatched vulnerabilities that can compromise your website’s security.
• Compatibility: Many themes and plugins require the latest PHP version to function correctly. Updating ensures that you can take advantage of new features.

How to Check Your Current PHP Version

Before you initiate the update process, it’s essential to know your current PHP version. Here’s how to check:

• Log in to your WordPress admin dashboard.
• Go to Tools > Site Health.
• Under the Info tab, look for the Server section, where you’ll find your current PHP version.

Backup Your WordPress Site

Before making any significant changes, such as updating PHP, it’s crucial to back up your website. This step is essential because it allows you to restore your site to its previous state in case anything goes wrong during the update.

Utilize plugins like UpdraftPlus for easy backups or consult our Website Audit services if you’d like assistance.

Updating PHP Versions via Hosting Provider

Most often, updating PHP is handled at the hosting level. Here’s a step-by-step guide:

Selecting the Right Hosting Provider

Your choice of hosting provider greatly influences your website’s performance and security. If you are considering a new host, take a look at our Hosting Comparison to make an informed decision.

Accessing Your Hosting Control Panel

To update PHP, log into your hosting account control panel (often cPanel or similar). Look for a section labeled Software or Programming, and find the PHP options.

Updating the PHP Version

Once you’re in the PHP settings, you will likely see a dropdown menu listing your current PHP version. Select the latest stable version (such as PHP 8.x) from the dropdown. Click on the Save or Update button to apply changes.

Using a WordPress Plugin to Update PHP

If your hosting provider does not allow you to upgrade PHP through their interface, you can use a plugin. Here’s how to do it:

Installing a PHP Management Plugin

Search for plugins designed to manage or update PHP versions. A popular choice is PHP Version Switcher. Here’s how you can install it:

• In your WordPress dashboard, go to Plugins > Add New.
• Search for “PHP Version Switcher”.
• Click on Install Now and then Activate.

Updating PHP Using the Plugin

Once activated, navigate to the plugin settings and select your desired PHP version from the available options. Save the changes to complete the update.

Testing Your Site After PHP Update

After updating PHP, it’s crucial to test your website to ensure that everything is functioning correctly.

Check for Compatibility Issues

Use tools like Query Monitor to identify any issues. If you notice errors or compatibilities, consider addressing them:

• Update plugins and themes to their latest versions.
• Consult the plugin documentation for support if errors persist.

Functional Testing

Thoroughly test the key features of your site, including:

• Forms
• Widgets
• Product pages (for e-commerce sites)
• Gallery or portfolio sections

If all works seamlessly, congratulations! You’ve successfully updated PHP on your WordPress site.

What to Do If Something Goes Wrong

Sometimes, despite all precautions, an issue may arise. Here’s what you can do:

Restore Your Backup

If your site experiences problems, restoring from the backup you created earlier can save the day.

Revert the PHP Version

If necessary, you can revert to your old PHP version through your hosting control panel or the plugin settings.

Additional Tips for Updating PHP

A few final considerations to ensure a smooth PHP update experience:

Regular Updates

Make it a practice to review and update PHP regularly since outdated versions can expose your site to vulnerabilities.

Monitor Your Website Performance

After updating PHP, monitor your site’s performance. Tools like GTmetrix can help analyze speed and functionality.

Introduce a Maintenance Plan

Consider investing in our Care Plans that offer regular updates and maintenance to your WordPress site, including PHP versions.
