Day 83: Memory Safety: Implementing Strict Verification in High-Scale PHP CMS
we explore one of the most dangerous issues in persistent PHP runtimes like Swoole and RoadRunner: memory leaks. Learn how tiny per-request leaks become catastrophic at massive scale, and how strict verification techniques keep high-performance CMS systems stable under extreme load.
We’ll cover strict typing, immutable request objects, garbage collection behavior, resource management, input validation, static analysis with PHPStan/Psalm, and practical strategies to prevent OOM crashes in long-lived PHP workers.
Build a leaky worker, detect memory growth, then refactor it into a memory-safe architecture using modern PHP engineering principles designed for 100M+ RPS systems.
