Zephir

Zephir - Ze(nd Engine) Ph(p) I(nt)r(mediate) - is a high level language that eases the creation and maintainability of extensions for PHP. Zephir extensions are exported to C code that can be compiled and optimized by major C compilers such as gcc/clang/vc++. Functionality is exposed to the PHP language.

Main features:

Both dynamic/static typing
Reduced execution overhead compared with full interpretation
Restricted procedural programming, promoting OOP
Memory safety
Ahead-of-time (AOT) compiler to provide predictable performance

Compiler design goals:

Multi-pass compilation
Type speculation/inference
Allow runtime profile-guided optimizations, pseudo-constant propagation and indirect/virtual function inlining

re2c

g++ >= 4.4 | clang++ >= 3.x | vc++ >= 11
GNU make >= 3.81
automake
