Understanding Drupal PHP Support: Release Cycles, Version Requirements, and Upgrade Strategies

Staff Reporter

This blog examines how Drupal’s PHP support cycle aligns with PHP’s rapid release pace. It explains Drupal’s release cadence, from lengthy major version pre-release stages to six-week minor version cycles. Major versions are supported for four years, with two years of active support and two years of security-only. Minor versions receive one year of combined active and security support.

The article clarifies the difference between compatible and recommended PHP versions, emphasising that “compatible” meets minimum requirements, while “recommended” offers optimal performance, security, and community backing. PHP requirements vary by Drupal version, with Drupal 10 needing PHP 8.1+, and Drupal 11 requiring PHP 8.3+, dropping support for older releases.

It highlights upgrade complexities, especially for enterprise sites with custom code, and outlines long-term support (LTS) options via Zend for teams unable to match the PHP community’s pace. While detailed, the piece serves more as a process guide than a roadmap for immediate deployment decisions.
