What PHP version should I use for Magento?

Recommended PHP Versions for Magento

At HostingDuty, we prioritize stability and performance for our Magento clients. The optimal PHP version depends heavily on your specific Magento 2 version. For the latest Magento 2.4.6 and beyond, PHP 8.2 is the officially supported and recommended version. This version delivers significant performance improvements over earlier releases, including faster execution times and lower memory usage.

Version Compatibility Matrix

Magento 2 has strict version requirements that must be met to ensure store stability. Here is the breakdown:

• Magento 2.4.0 to 2.4.5: These versions support PHP 7.4, 8.0, and 8.1. However, PHP 7.4 reached end-of-life in November 2022, meaning it no longer receives security updates. We strongly advise against running Magento on PHP 7.4 for production environments.
• Magento 2.4.6 and later: These versions officially support PHP 8.1 and 8.2. PHP 8.2 is the current best practice for new installations and upgrades.

Performance Implications

Upgrading to PHP 8.2 is not just about security; it is a performance upgrade. The Just-In-Time (JIT) compiler improvements in PHP 8.1 and 8.2 significantly speed up Magento operations, particularly during heavy indexing and checkout processes. You can read more about the specific performance impacts in our analysis of PHP versions and Magento 2 performance.

Upgrade Considerations

Before upgrading your PHP version, we recommend the following steps:

1. Backup your environment: Always create a full backup of your database and file system. 2. Test in Staging: Deploy your store on a staging environment to test for compatibility issues with custom modules or themes. 3. Check Extensions: Ensure all third-party extensions are compatible with the target PHP version. Some older extensions may not support PHP 8.2 yet.

For detailed guidance on managing your environment, see our guide on PHP upgrade procedures and our Magento 2 configuration best practices.

Security Updates

Using an unsupported PHP version exposes your store to known vulnerabilities. Magento and the PHP Foundation both release critical security patches regularly. HostingDuty ensures our infrastructure supports the latest PHP versions to keep your store secure. For more information on security hardening, check our Magento security hardening documentation.
