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
To compile zephir-parser:
To build the PHP extension:
- g++ >= 4.4/clang++ >= 3.x/vc++ 9
- gnu make 3.81 or later
- php development headers and tools
You can install zephir using composer.
Run composer require phalcon/zephir, 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.
The following packages are needed in Ubuntu:
- apt-get install re2c libpcre3-dev
Compile the extension:
./bin/zephir compileZephir is open-sourced software licensed under the MIT License. See the LICENSE file for more information.
