Developer Briefing — November 25, 2025

Executive briefing: The PHP project’s supported versions schedule shows PHP 8.1 exiting security support on 25 November 2025. After this date, upstream will no longer ship CVE patches. Engineering and SRE teams must upgrade runtime images to PHP 8.2 or 8.3, validate framework compatibility, and retire lingering 8.1 containers or functions before the cutoff.

Key risk themes

• Unpatched vulnerabilities. Applications pinned to PHP 8.1 will miss future security releases, raising breach risk and audit findings.
• Supply-chain drift. Many package repositories and container base images will stop producing 8.1 artifacts after November 2025, complicating reproducible builds.
• Runtime support contracts. Commercial support providers may charge premiums or decline coverage for out-of-support runtimes.

Operational priorities

• Dependency assessment. Run automated compatibility scans and unit tests against PHP 8.2/8.3 to surface deprecated APIs before production cutovers.
• Image hardening. Refresh container baselines with maintained PHP versions, rebuilding images that embed PHP-FPM, Nginx, or Apache modules.
• Change management. Schedule phased rollouts with health checks and error-budget guardrails, especially for customer-facing workloads.

Enablement moves

• Publish migration guides noting common extension updates (Intl, mbstring) and framework-specific notes (Laravel/Symfony) for 8.2/8.3.
• Update service-level objectives and vulnerability SLAs to treat PHP 8.1 as non-compliant after November 2025.

• PHP supported versions calendar
• PHP 8.1 changelog and lifecycle notice

Zeph Tech orchestrates runtime upgrades, container rebuilds, and automated regression testing to keep PHP services patched and compliant.
