PrestaShop PHP Version Compatibility Chart

Which PHP version is compatible with PrestaShop? The short answer depends on your PrestaShop version: PrestaShop 9 requires PHP 8.1 or newer, while older PrestaShop 8, 1.7 and 1.6 stores need stricter version matching.

Use this compatibility chart before changing PHP on your server. A wrong PHP upgrade can break modules, overrides, checkout or the back office.

Meeting the system requirements for PrestaShop will help keep your online store from encountering unexpected errors.

Switching your current PHP version to the latest will definitely make your store faster; however, each PrestaShop version only supports certain PHP.

Let's see what version of PHP your online store will be ready with.

PrestaShop 1.6 supports PHP version 5.2 to 7.1

This PS version was released in 2014. This PS supports PHP 5.2 to PHP 7.1. At that time, upgrading from PS 1.5 to 1.6 was a painful, nearly "shattering to reconstruct" process.

PrestaShop 1.7 is compatible with PHP version 5.4 to 7.4

The first stable version of PS 1.7 was released in November 2016. You can install PHP 5.4 to PHP 7.4 on your web server to host your online store.

The 3 most commonly used at the moment are PHP 7.2, PHP 7.3 and PHP version 7.4.

PrestaShop 8 needs PHP 7.2.5 to 8.1 on your server.

The newest version of PrestaShop has been released in November 2022. This latest PrestaShop package (now PrestaShop 8.0.3) works as an open source project and supports the latest PHP version 8.1. It's also compatible with PHP 7.3 as well as compatible with PHP 7.4.

Our recommendation? It would be worthwhile to upgrade to the latest version 8.0 because at least it can significantly accelerate the performance of your PrestaShop store.

Are the supported versions of PHP not ready on your hosting? You need to contact your hosting provider to update PHP or change PHP version to a newer one for your account. If it's impossible, backup your website and find a better hosting.

PrestaShop 8.2 supports PHP 8.1 and PHP 8.2

PrestaShop 8.2, released in 2024, brought full support for PHP 8.2 alongside continued compatibility with PHP 8.1. This version introduced significant performance improvements and security patches. If you are running PrestaShop 8.x, we strongly recommend upgrading to PHP 8.2 for optimal speed and security.

Key PHP improvements in PS 8.2:

• Full PHP 8.2 support (readonly classes, DNF types)
• Improved memory usage and execution speed
• Better compatibility with modern hosting environments

PrestaShop 9.0 requires PHP 8.1 to 8.3

PrestaShop 9.0, the latest major release (2025), is built on the Symfony 6.4 framework and requires a minimum of PHP 8.1. It fully supports PHP 8.2 and PHP 8.3. Legacy PHP versions (7.x) are no longer supported.

PrestaShop 9 represents a major architectural shift:

• Symfony 6.4 LTS framework
• PHP 8.1 minimum, PHP 8.3 recommended
• MySQL 5.7+ or MariaDB 10.4+
• Modernized admin panel with Symfony controllers
• Improved module compatibility layer
