PHP lacks structured concurrency despite having fibers and an event loop, unlike languages such as Python, Kotlin, Swift, and Java that have implemented it. The article traces how programming evolved by trading freedoms for machine-enforceable guarantees—from eliminating goto to managed memory—and argues structured concurrency should follow the same pattern by confining tasks to scopes with guaranteed cleanup. Two RFC proposals for PHP structured concurrency failed due to process concerns and uncertainty about effects on global state, though the author argues a userland library rather than engine changes could solve the problem.
