This Week In PHP Internals | July 15, 2026
This Week in PHP Internals — July 8 to July 15, 2026. A brand-new class extension proposal rewrote itself mid-thread, the Deprecations RFC froze with ballots set for July 27, function autoloading split off a prerequisite RFC overnight, Duration picked up its first declared no on the eve of its vote, and a JSX-flavored markup RFC landed hours before recording. An Artisan Build production.
