PHP version of PrestaShop 9

  • Updated

It is useful to use a recent version of PHP, especially to secure your store and improve its performance. Version 9 of PrestaShop supports up to version 8.4 of PHP.

 

⚠️ PrestaShop 9 no longer supports PHP7.x, and requires at least PHP8.1.

 

Before updating your PHP version

  • Please check the compatibility of your theme and modules with the new version of PHP.
  • Carry out tests in a pre-production environment if possible.
  • Save a backup of your site and database before making any changes.

 

How to update the PHP version of your store

The procedure depends on your hosting environment:

1. Shared hosting (e.g. cPanel, Plesk)

  1. Log in to your hosting control panel (e.g. cPanel).

  2. Go to "Select PHP Version" or "PHP Manager".

  3. Choose a more recent PHP version (e.g. from 7.4 to 8.1 or 8.2).

  4. Save or apply the changes.

  5. Clear the PrestaShop cache: Access the foldervar/cache/ and delete the foldersprod/ ordev/ depending on your environment.

2. VPS or dedicated server

If you have control of your server:

  • On Ubuntu/Debian:

    bash
CopierModifier
sudo add-apt-repository ppa:ondrej/php
sudo apt update
sudo apt install php8.2
sudo update-alternatives --set php /usr/bin/php8.2

  • Update the necessary PHP extensions (php8.2-mysql, php8.2-curl, etc.).

  • Restart your web server (sudo systemctl restart apache2 orphp-fpm).

3. Docker

If you are using Docker for PrestaShop, modify yourDockerfile ordocker-compose.yml to use a base image with the desired PHP version.
