Hello, PrestaShop aficionados! If you’ve been following my blog, you know how much I emphasize the importance of compatibility when it comes to running a smooth and efficient online store.

Today, we’re diving into a crucial aspect of that: PHP versions compatible with different PrestaShop versions.

With over ten years of experience in PrestaShop development, I can’t stress enough how vital it is to match your PHP version with your PrestaShop version for optimal performance.

Why PHP Version Matters

PHP is the backbone of your PrestaShop store. It’s the scripting language that powers the server-side of your website. Using an incompatible or outdated PHP version can lead to issues ranging from minor glitches to significant security vulnerabilities and even site crashes. Therefore, it’s crucial to ensure that your server’s PHP version is compatible with the PrestaShop version you’re using.

PrestaShop 1.6: PHP Version Compatibility

For those running older stores on PrestaShop 1.6, the PHP versions you can safely use range from 5.2 to 7.1. While it might be tempting to stick with older PHP versions for compatibility reasons, using the latest supported version for security and performance improvements is generally a good idea.

Recommended Action: If you’re on PrestaShop 1.6, aim for PHP 7.1 for the best balance of compatibility and performance.

PrestaShop 1.7: PHP Version Compatibility

PrestaShop 1.7 brought several improvements and is compatible with PHP versions from 5.4 to 7.4. If you’re running a store on this version, you have a broader range of PHP versions to choose from. However, as always, newer is often better for performance and security.

Recommended Action: For PrestaShop 1.7, PHP 7.4 is your best bet. It offers excellent performance and security features, ensuring your store runs smoothly.

PrestaShop 8: PHP Version Compatibility

The latest and greatest, PrestaShop 8, requires more modern server environments. It is compatible with PHP versions 7.2.5 to 8.1. If you’re planning to upgrade to PrestaShop 8 or start a new store, you’ll need to ensure your server is up-to-date.

Recommended Action: For PrestaShop 8, PHP 8.1 is the way to go. It’s the latest supported version, offering cutting-edge performance and security enhancements.

How to Check and Update Your PHP Version

  1. Check Current Version: You can check your current PHP version from your hosting control panel or by creating a simple PHP file with <?php phpinfo(); ?> and accessing it via your web browser.
  2. Consult Hosting Provider: If you’re not comfortable changing PHP versions yourself, consult your hosting provider. They can guide you through the process.
  3. Update PHP Version: Most hosting control panels like cPanel or Plesk allow you to change your PHP version with just a few clicks. Make sure to backup your website before making any changes.
  4. Test: After updating, thoroughly test your website to ensure that everything is working as expected.


Ensuring that your PrestaShop store runs on a compatible PHP version is crucial for performance and security. Always aim for the latest PHP version that your PrestaShop version supports. This guide should serve as a quick reference for anyone confused about which PHP version to use with PrestaShop 1.6, 1.7, or 8.
