Upgrading Your WordPress Site’s PHP Version for Better Performance and Security


Keeping your WordPress system up-to-date is essential, but have you ever checked your PHP version recently? PHP versions play a crucial role in your website’s performance and security. However, many website owners tend to overlook this, much like neglecting smoke detectors until they start beeping. In this comprehensive guide, we will delve into the importance of upgrading your site’s PHP version and provide you with a step-by-step guide on how to manage PHP upgrades effectively.

Understanding PHP

PHP serves as a scripting language for web development and powers over three-fourths of all websites globally. In the WordPress ecosystem, PHP plays a pivotal role as it processes the PHP code that ultimately renders your WordPress pages and posts. Your WordPress core system files, themes, and plugins all contain PHP code, making it a vital component of your website’s functionality.

WordPress PHP Version Requirements

As of WordPress 6.0’s release in May 2022, the platform requires servers to run PHP version 7.4 or higher. While WordPress may function on older PHP versions exceeding 5.6.20, it is not recommended. In the following sections, we will explore why upgrading your PHP version is a wise decision.

Why Upgrading Your PHP Version Matters

The PHP development team provides full support for each PHP version for two years after its initial release. During this period, regular updates are released to address bugs and security vulnerabilities. However, after this two-year period, PHP versions receive only one additional year of security support, and no other updates are provided. Beyond this timeframe, a PHP version reaches its end of life and will no longer receive updates or support.

For instance, PHP 8.1, the latest version as of November 25, 2021, saw its security support ending on November 28, 2022. Using an unsupported PHP version poses significant risks to your website’s security and stability.

Benefits of Upgrading PHP Versions

Upgrading your PHP version offers several advantages:

1. Enhanced Site Speed

  • Outdated PHP versions can slow down your website. Newer PHP versions are optimized for performance, ensuring faster loading times.

2. Improved Security

  • Running an outdated PHP version exposes your site to security threats. Upgrading to the latest PHP version ensures you have the latest security features and patches, akin to locking your front door securely before leaving for vacation.

3. Access to New Features

  • New PHP versions introduce updated features that plugin and theme developers may utilize. Staying up-to-date allows you to leverage these features for improved functionality.

4. Better Support

  • Upgrading PHP ensures you receive regular bug fixes and patches. Your web host may also require you to upgrade PHP before offering support, ensuring a smoother hosting experience.

How to Upgrade PHP Versions

Now that we understand the importance of upgrading PHP versions let’s explore the steps to achieve this:

1. Check Your Current PHP Version

  • Utilize your hosting provider’s tools or WordPress admin to identify your current PHP version.

2. Confirm Host Support

  • Ensure your hosting provider supports the PHP version you wish to upgrade to. Some hosts, like Pressable, always offer the latest PHP version compatible with WordPress.

3. Create a Site Backup

  • Before upgrading PHP, create a backup of your site to safeguard against potential issues during the upgrade process.

4. Update WordPress

  • Make sure your WordPress software is up to date before switching your PHP version. Managed hosting plans typically run the latest WordPress version.

5. Switch Your PHP Version

  • Log in to your hosting account and follow your host’s instructions to switch to the desired PHP version. Consider testing the upgrade in a staging environment first for a seamless transition.

6. Check for Errors

  • Review your site for any post-upgrade issues, especially in themes, plugins, and custom code. Isolate the problem by systematically deactivating plugins and testing themes.

7. Update Plugins and Themes

  • Check for updates in your themes and plugins, install them, and verify that your site functions correctly.

8. Finalize Your Update

  • After thorough testing, apply the changes to your live site, ensuring everything looks and works as expected.


Upgrading your WordPress site’s PHP version is a vital aspect of maintaining its performance and security. Ignoring PHP updates can leave your site vulnerable to security threats and hinder its speed. By following the steps outlined in this guide, you can ensure your site runs on the latest PHP version, benefiting from improved performance, enhanced security, and access to new features. If you’re looking for a hassle-free hosting experience, consider a managed hosting platform like Pressable, where PHP versions and WordPress updates are managed for you, ensuring your site remains up-to-date and secure.
