Introduction

Maintaining your WordPress website is crucial for its performance, security, and overall functionality. One important aspect of this maintenance involves updating PHP, the programming language that powers WordPress. This article will provide a comprehensive guide on how to update WordPress PHP, along with the benefits, use cases, and tips for accomplishing this task seamlessly. Whether you’re a seasoned WordPress user or new to the platform, this guide will equip you with the knowledge needed to keep your site running smoothly.

Why Update WordPress PHP

Before diving into the details of how to update WordPress PHP, let’s first discuss why this update is essential for your website. PHP powers WordPress and influences everything from speed to security. Keeping your PHP version up to date has several benefits:

Performance Improvements

Newer versions of PHP often come with enhancements that significantly improve site performance. Faster loading times can improve user experience, potentially leading to higher conversion rates. For instance, switching from PHP 7.0 to PHP 7.4 can yield performance boosts by reducing memory consumption and execution times.

Security Enhancements

Older PHP versions may not receive security updates, leaving your site vulnerable to attacks. Regularly updating ensures that your site benefits from the latest security fixes and patches. According to [WordPress.org](https://wordpress.org/support/article/upgrading-wordpress/), running an outdated version can expose you to various security threats.

Compatibility with Plugins and Themes

Many themes and plugins are developed using the latest PHP standards. Running an outdated PHP version can lead to compatibility issues, which may cause plugins and themes to malfunction. Keeping your PHP updated ensures a smooth experience.

How to Check Your Current PHP Version

Before updating, it’s crucial to know which PHP version your WordPress site is currently running. Here’s how you can check:

Using WordPress Dashboard

1. Log in to your WordPress dashboard.

2. Go to “Tools” and select “Site Health.”

3. Click on “Info” and then look for “Server” to find the current PHP version.

Using a Plugin

If you prefer using plugins for site management, many options can help with this. The “Display PHP Version” plugin displays your PHP version directly in the dashboard. Install it from [WordPress Plugin Repository](https://wordpress.org/plugins/display-php-version/), and you’ll have this information readily available.

How to Update WordPress PHP

Updating PHP may seem daunting, but it can be done easily with the right approach. Here’s how to update WordPress PHP safely:

Step 1: Backup Your Website

Never attempt to update your PHP version without backing up your site first. This step ensures that you can restore your site if anything goes wrong during the update. You can use plugins like [UpdraftPlus](https://wordpress.org/plugins/updraftplus/) or work with your hosting provider to create a backup.

Step 2: Check Hosting Account Settings

Most web hosting services allow you to change your PHP version through the hosting control panel. Here are general steps you might take:

1. Log in to your hosting account (e.g., cPanel or another control panel).

2. Navigate to the “Select PHP Version” or “PHP Configuration” section.

3. Choose the desired PHP version from the dropdown menu.

4. Click “Save” or “Apply changes.”

Step 3: Update PHP via SSH (Advanced Users)

If you’re comfortable with the command line, you can update PHP via SSH:

1. Access your server using an SSH client.

2. Use commands like `php -v` to check the current version.

3. Run `sudo apt-get install php7.x` (replace ‘7.x’ with your desired version) to install the update.

4. Restart the web server to apply changes.

Step 4: Test Your Website

After the PHP update is complete, it’s essential to test your website thoroughly. Check for any broken links, missing functionality, or error messages. Perform a website audit using our [Website Audit service](https://website.care/wordpress-website-audit) to ensure everything is functioning correctly post-update.

Common Issues After PHP Update

Updating PHP can sometimes lead to issues with themes or plugins. Here’s how to handle common challenges:

Plugin Incompatibility

After updating PHP, some plugins may not function correctly due to compatibility issues. Check for updates from the plugin developers or look for alternatives. If a plugin causes problems, consider disabling it and reaching out to the developer for assistance.

Theme Errors

Similarly, outdated themes can cause issues after a PHP update. Ensure that your theme is compatible with the latest PHP version, and consider switching to a more stable theme if problems persist.

Debugging

If your site encounters errors after the update, enable WordPress debugging to gather more information. Add the following lines to your `wp-config.php` file:

define( 'WP_DEBUG', true );

define( 'WP_DEBUG_LOG', true );

define( 'WP_DEBUG_DISPLAY', false );

This will log errors to a file named debug.log, giving you more context on any issues your site may be experiencing.

Best Practices for Managing PHP Updates

To ensure the continued performance of your WordPress website, consider following these best practices:

Regularly Update Everything

Stay on top of updates not only for PHP but also for WordPress core, themes, and plugins. Keeping everything up to date minimizes security vulnerabilities and compatibility issues.

Test in Staging Environment

If your hosting provider supports staging sites, use it. Test PHP updates in a staging environment before rolling them out on your live site. This will allow you to address any issues without impacting your users.

Utilize Professional Support

If managing updates feels overwhelming, consider seeking professional assistance. Our [Customer Support](https://website.care/wordpress-customer-support) service offers guidance and solutions to keep your WordPress site in top shape.

Comparing PHP Hosting Options

Not all hosting providers are created equal. As you consider updating PHP, it may be worthwhile to evaluate your hosting options:

Shared Hosting vs. Managed WordPress Hosting

Shared hosting is often less expensive but may not provide the optimal environment for running the latest PHP versions. Managed WordPress hosting is engineered exclusively for WordPress, offering better speed, security, and support for PHP updates.

Enterprise Hosting Solutions

If your website requires high availability and performance, an enterprise hosting plan could be the right choice. These plans offer more resources and customization options, which could be beneficial when managing PHP updates.
