Hi internals, I'd like to start the discussion for a new RFC, OPcache Static Cache.
RFC: https://wiki.php.net/rfc/opcache_static_cache Implementation: https://github.com/php/php-src/pull/22052 The proposal adds an OPcache-managed shared-memory cache for explicit userland values and for selected PHP static state. It introduces explicit functions under the OPcache namespace (volatile_* and persistent_*) and two attributes, #[OPcache\VolatileStatic] and #[OPcache\PersistentStatic], that let selected static properties and method static variables survive across requests. The feature is disabled by default and only activates once memory is allocated through the new INI directives. The RFC covers the motivation, the deliberate split between the two backends, the trust model (one PHP runtime = one trust domain; this is not a tenant isolation boundary), and benchmarks against APCu on NTS php-fpm and ZTS FrankenPHP. The PR is the full implementation, with PHPT coverage summarized in the Validation section. One thing to flag on the implementation status: the Windows build is currently broken. I don't have a Windows development environment available yet — one is being arranged through work, and I'll get the Windows side fixed once that's in place. Feedback welcome. Best Regards, Go Kudo
