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 >= 0.13.6
- Zephir Parser >= 1.1.0
- A C compiler such as
gcc>= 4.4 or an alternative such asclang>= 3.0,Visual C++>= 11 orIntel C++. It is recommended to usegcc4.4 or later - GNU
make>= 3.81 automake- PHP development headers and tools
- The
build-essentialpackage when usinggccon Ubuntu (and likely other distros as well)
NOTE: The development branch will always contain the latest unstable version.
If you wish to check older versions or formal, tagged release, please switch to the relevant
branch/tag.
