Upgrading PHP: Will It Break My Site?

As a web developer, I understand the importance of keeping up with the latest technologies and updates. However, when it comes to upgrading PHP, many website owners have concerns about the potential impact on their site’s functionality. In this article, I will delve deep into the topic and provide you with insights on whether upgrading PHP will break your site.

The Benefits of Upgrading PHP

Before we dive into the potential risks, let’s first discuss the benefits of upgrading PHP. PHP is a widely-used programming language that powers a significant portion of the web. With each new release, PHP brings improvements in performance, security, and new features. By upgrading PHP, you can take advantage of these advancements and enhance your website’s speed, security, and functionality.

Additionally, upgrading PHP ensures that your site is compatible with the latest web standards and frameworks. This is crucial for maintaining optimal performance and ensuring a seamless user experience.

The Potential Risks

While upgrading PHP offers numerous benefits, it’s important to be aware of the potential risks associated with the process. One of the primary concerns is the compatibility of your existing codebase with the new version of PHP.

Over time, PHP evolves, and certain functions or syntax may become deprecated or incompatible with newer versions. If your website relies heavily on deprecated features or outdated coding practices, upgrading PHP could indeed break your site. However, it’s important to note that most PHP upgrades provide detailed documentation on deprecated features and migration steps to help developers smoothly transition their code.

Another potential risk is the compatibility of third-party plugins or themes. If your website relies on any plugins or themes that have not been updated to work with the latest version of PHP, you may experience compatibility issues. It’s crucial to ensure that all plugins and themes are compatible with the PHP version you plan to upgrade to. Most reputable plugin developers provide updates to ensure compatibility, but it’s always wise to check before proceeding with the upgrade.

Best Practices for Upgrading PHP

When considering a PHP upgrade, it’s important to follow best practices to minimize the risks and ensure a smooth transition:

  1. Backup Your Site: Before making any changes, create a backup of your entire site, including the database. In case anything goes wrong during the upgrade process, you can easily restore your site to its previous state.
  2. Update Your Code: Review your codebase and identify any deprecated functions or syntax. Make the necessary updates to ensure compatibility with the new PHP version. This might involve rewriting certain code segments or using alternative functions.
  3. Check Plugin and Theme Compatibility: Verify that all third-party plugins and themes are compatible with the PHP version you plan to upgrade to. Visit the developers’ websites or contact their support if necessary.
  4. Test in a Staging Environment: Set up a staging environment, which is an exact copy of your site, to perform the PHP upgrade. This allows you to test and identify any compatibility issues before applying the changes to your live site.
  5. Monitor Your Site: After the upgrade, closely monitor your site for any unexpected behavior or compatibility issues. Test all critical features, forms, and functionalities to ensure everything is functioning as expected.


Upgrading PHP can bring significant benefits to your website’s performance, security, and functionality. While there are potential risks involved, following best practices and taking necessary precautions can help ensure a smooth transition. Remember to always backup your site, update your code, check plugin and theme compatibility, and test extensively before upgrading PHP. By doing so, you can reap the rewards of a modern PHP version without breaking your site.
