Supported PHP versions receive regular bug and security updates. A web application “still opening” does not mean its runtime is secure and sustainable.
Active support and security support
PHP versions first pass through active support, then a period of critical security fixes only. Once a branch leaves support, the team maintaining the app must carry known issues on its own.
How to plan an upgrade
- Inventory current PHP and extension versions.
- Scan deprecated functions and third-party packages.
- Test real user flows in a staging environment.
- Verify database, queues, cron and file permissions together.
- Never upgrade production without a rollback plan.
The WYN approach
We treat a runtime upgrade not as one-off tech debt cleanup, but as an investment that widens the product’s future room to move. Security updates, performance and maintenance cost are evaluated on the same table.
