Why PHP Updates Matter for Your WordPress Performance

Before we jump into the nitty-gritty details of PHP updates, let’s take a moment to understand why they matter for your WordPress performance. PHP is the scripting language that powers WordPress, and it plays a crucial role in how your website functions. Upgrading to the latest version of PHP can significantly improve your website’s speed, security, and overall performance.

Speed Boost: Say Goodbye to Loading Delays

One of the most significant benefits of PHP updates is the speed boost they provide to your WordPress site. As technology advances, so does PHP, and newer versions are often optimized for better performance. PHP updates introduce new features and improvements that can speed up your website’s response time and reduce loading delays. This means your visitors will be able to access your site faster, leading to a better user experience and potentially higher conversion rates.

Enhanced Security: Protect Your Website from Threats

Security should always be a top priority for any website owner. Hackers and malicious actors are constantly evolving their tactics to infiltrate websites and steal sensitive data. By keeping your PHP version up to date, you ensure that you have the latest security patches and bug fixes, making it harder for attackers to exploit vulnerabilities in outdated versions. Upgrading to the latest PHP version can significantly enhance your website’s security and protect your valuable business and customer data.

Compatibility and Support: Stay Up to Date with WordPress

WordPress is a dynamic platform that is continuously evolving. With each new release, WordPress introduces new features and improvements that enhance the functionality and performance of your website. However, these updates often require a compatible PHP version to work seamlessly. By keeping your PHP version updated, you ensure compatibility with the latest WordPress versions and plugins, allowing you to take full advantage of the platform’s capabilities and receive ongoing support from the WordPress community.

How to Check Your Current PHP Version

Now that you understand the importance of PHP updates let’s find out how you can check your current PHP version. It’s essential to know which version you’re currently running before proceeding with any updates or changes. Checking your PHP version is a straightforward process, and there are multiple ways to do it.

Method 1: Using a WordPress Plugin

If you’re comfortable navigating the WordPress dashboard, installing a plugin is the easiest way to check your PHP version. One popular plugin for this purpose is "Display PHP Version." Simply search for the plugin in your WordPress plugin directory, install and activate it. Once activated, you can find your PHP version by navigating to the "Dashboard" > "At a Glance" section in your WordPress admin area.

Method 2: Through Your Hosting Control Panel

Another way to check your PHP version is through your hosting control panel. Most hosting providers offer a control panel such as cPanel or Plesk, where you can manage various aspects of your website. Log in to your hosting control panel and look for the PHP version section. The exact location may vary depending on your hosting provider, but it’s usually under the "Software" or "Advanced" settings.

Method 3: Using a PHP Info Page

For the more technically inclined, you can create a PHP info page to check your PHP version. Simply create a new text file with the following code:

Save the file as phpinfo.php, upload it to your website’s root directory using FTP or your hosting control panel’s file manager, and access it through your web browser (e.g., http://yourwebsite.com/phpinfo.php). You’ll see a comprehensive page with all the PHP information, including the version.

Understanding PHP Versions and Support Lifecycle

Now that you’ve determined your current PHP version let’s dive into the different PHP versions and their support lifecycle. PHP is an open-source language with multiple versions available, each with its own set of features and support timeline. It’s crucial to understand the PHP version you’re running and its support status to make informed decisions regarding updates and compatibility.

PHP 5.6: End of Life

If your website is running on PHP 5.6 or older versions, it’s time to take action. PHP 5.6 reached its end-of-life (EOL) on December 31, 2018, which means it’s no longer receiving security updates or bug fixes. Continuing to use PHP 5.6 poses a significant risk to your website’s security and functionality. It’s highly recommended to upgrade to a supported PHP version as soon as possible.

PHP 7.0 – 7.3: Active Support

PHP 7.0 was released in December 2015, followed by PHP 7.1, 7.2, and 7.3 in subsequent years. As of the time of writing this blog post, PHP 7.0 and 7.1 are no longer receiving active support, but PHP 7.2 and 7.3 are still actively supported. Active support means that these versions receive security updates and bug fixes, ensuring a secure and stable environment for your WordPress site.

PHP 7.4: The Latest Stable Release

PHP 7.4 is the latest stable release and the recommended version for most WordPress websites. It brings significant performance improvements and new features while maintaining high compatibility with existing codebases. PHP 7.4 is actively supported and receives regular updates. If your website is running on an older PHP version, upgrading to PHP 7.4 can provide a substantial boost in speed and security.

Upgrading to a Newer PHP Version

Now that you’re familiar with PHP versions and their support lifecycle let’s talk about the process of upgrading to a newer PHP version. Upgrading your PHP version can be a straightforward task, but it’s crucial to follow the correct steps to ensure a smooth transition without causing any compatibility issues or downtime.

Step 1: Backup Your Website

Before making any changes to your website, it’s crucial to create a full backup. While the chances of something going wrong during the PHP update process are minimal, having a backup ensures that you can easily restore your website to its previous state if anything unexpected happens.

Step 2: Check Plugin and Theme Compatibility

While most plugins and themes are compatible with the latest PHP versions, it’s always a good idea to double-check before upgrading. Visit the websites of your theme and plugin developers and look for compatibility information. If they explicitly state that their products are compatible with PHP 7.4, you can proceed with the update confidently. However, if there are compatibility concerns, reach out to the developers for guidance or consider finding alternative solutions.

Step 3: Update WordPress Core

Before updating PHP, it’s crucial to ensure that your WordPress installation is up to date. Running the latest version of WordPress minimizes the chances of compatibility issues when upgrading PHP. If you have any pending WordPress updates, complete them before proceeding.

Step 4: Contact Your Hosting Provider

The process of upgrading PHP depends on your hosting provider. Some hosting providers allow you to change your PHP version through the hosting control panel, while others require you to contact their support team for assistance. Reach out to your hosting provider and inquire about their PHP update process. They will guide you on the necessary steps to upgrade your PHP version.

Step 5: Test Your Website

After upgrading PHP, it’s crucial to thoroughly test your website to ensure everything is functioning as expected. Visit different pages, perform various actions, and check for any errors or inconsistencies. If you encounter any issues, refer to your backup and consider reaching out to a professional website developer for assistance.

By following these steps, you can smoothly upgrade your PHP version and take full advantage of the performance and security benefits offered by the latest PHP releases.
