Developer Enablement Briefing — PHP 8.2 security support sunset
PHP 8.2 exits security support at year end 2025, pressing product teams to finish runtime upgrades, dependency validation, and compliance evidence before the long-tail patch window closes.
Executive briefing: The PHP core team retires version 8.2 from active security support on December 31, 2025, concluding the language’s three-year lifecycle. After that date the project stops releasing official security patches, leaving unpatched vulnerabilities to accumulate across content management systems, e-commerce platforms, and custom workloads still pinned to 8.2. Engineering leaders must accelerate migrations to PHP 8.3 or later, validate framework compatibility, and capture change-control evidence before compliance auditors flag unsupported runtimes.
Key engineering signals
- Official lifecycle. The PHP Foundation’s supported versions matrix lists December 2025 as the final month for 8.2 security fixes, with no extended support channel.
- Framework alignment. Major ecosystems—Symfony 7, Laravel 11, Drupal 11—have already declared compatibility with PHP 8.3, reducing blockers for production upgrades.
- Dependency exposure. Composer package maintainers are publishing notices that future releases will require PHP 8.3+, signalling imminent deprecation of 8.2 compatibility flags.
Control alignment
- SOC 2 CC7 and CC8. Document runtime upgrade plans, regression testing, and deployment approvals to prove unsupported software risk is mitigated.
- PCI DSS 6.3.2. Merchants using PHP-based commerce stacks must show they patched or upgraded to a supported runtime before the December deadline.
- ISO/IEC 27001 A.12.6.1. Maintain vulnerability management records that trace CVE remediation to the PHP engine uplift.
Detection and response priorities
- Instrument SBOM scanners and vulnerability management tools to flag services still running PHP 8.2 as the sunset approaches.
- Alert when Composer lockfiles or container base images reference 8.2 builds, triggering remediation workflows.
Enablement moves
- Stand up parallel staging stacks on PHP 8.3 or 8.4, executing regression and performance test suites alongside production traffic simulations.
- Coordinate with CMS and plugin vendors to validate upgrade windows, ensuring third-party modules ship compatible releases before the support cutoff.
- Update documentation, runbooks, and customer communications so client success teams can explain the security rationale for runtime migrations.
