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

Requirements

To compile zephir-parser:

  • json-c (Please install this one from Github)
  • re2c

To build the PHP extension:

  • g++ >= 4.4/clang++ >= 3.x/vc++ 9
  • gnu make 3.81 or later
  • php development headers and tools

Installation

You can install zephir using composer. Run composer require phalcon/zephir, run ./install and then run zephir from your bin-dir. By default it is ./vendor/bin/zephir. You can read more about composer binaries in it's documentation.

For global installation via composer you can use composer global require. Do not forget add ~/.composer/vendor/bin into your $PATH.

Also you can just clone zephir repository and run ./install. For global installation add -c flag.

Additional notes on Ubuntu

The following packages are needed in Ubuntu:

  • apt-get install re2c libpcre3-dev

Usage

Compile the extension:

./bin/zephir compile
