Zephir Language

Zephir - Ze(nd Engine) Ph(p) I(nte)r(mediate) - is an open source high level language that eases the creation and maintainability of C-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.

Zephir aims for near full interoperability with existing php code.

Main features:

  • Both dynamic/static typing
  • Reduced execution overhead compared with full interpretation
  • Restricted procedural programming, promoting OOP
  • Memory safety
  • Ahead-of-time compiler

Compiler design goals:

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

Installation

xx is the parser for the language:

Requirements:

json-c re2c

Installation on Ubuntu

sudo apt-get install libjson0 libjson0-dev libjson0-dbg
sudo apt-get install re2c

Once you have the required packages installed, you can generate the parser as follows:

./generate

Usage

Compile the extension:

./zephir

The code produced is placed in ext/, there you can perform the standard compilation:

cd ext/
sudo ./install

The code is maintained on Github

Zephir is going to be the language that will drive the development of phalcon 2.0 ( http://www.phalconphp.com/en/)

Support

Due to the fact that the language is very young, support is not offered at this point. General questions can be posted in the Phalcon Forum.
