Could you build this?
No Building a zero-extension tracer that pauses live PHP execution and inspects variables requires deep Zend engine internals knowledge or low-level OS profiling primitives.
What it would actually take: A real implementation requires either dynamic AST rewriting via PHP-Parser to inject execution hooks and fiber-like stepping loops, or low-level systems tracing using eBPF, ptrace, and procfs to inspect process memory. The architecture involves an instrumentation daemon written in C or Rust that coordinates with the PHP runtime and streams call trees over WebSockets to a flamegraph frontend. This requires deep systems programming and PHP runtime internals expertise that cannot be vibe-coded.
