在「JIT for PHP project」這邊看到 PHP 新的翻修計畫：
I'm glad to say that we have started a new JIT for PHP project and hope to deliver some useful results for the next PHP version (probably 8.0).
We are very early in the process and for now there isn't any real performance improvement yet. So far we spent just 2 weeks mainly working on JIT infrastructure for x86/x86_64 Linux (machine code generation, disassembling, debugging, profiling, etc), and we especially made the JIT code-generator as minimal and simple as possible. The current state, is going to be used as a starting point for research of different JIT approaches and their usability for PHP.
