Atomic deploys with automatic rollback for PHP and WordPress
Release folders, a symlink swap that is truly atomic, rollback when a post-deploy step fails, and the OPcache and permission traps that catch people out.
Deployment configuration needs one clear owner
Define which source owns each deployment configuration file, then test that old local copies cannot silently override an intended change.
Test the oldest PHP version your site actually runs
A clean local lint is useful, but I also check the runtime that receives the deployment.
Keep a rollback route when moving PHP
I move the web server onto a separately tested PHP runtime, keep a clear route back, and check cron and background work as part of the change.
