PeachPie Compiler

The open-source PHP compiler to .NET

We recommend using the project with caution and testing it thoroughly before utilizing PeachPie in a production environment. There may still be inconsistencies and incompatibilities with the PHP language; if you run into any issues, kindly let us know and we'll do our best to address them. Take a look at our Roadmap to see which features and extensions we still have to implement.

We are now a member of the .NET Foundation!

What is PeachPie?

PeachPie is a modern PHP compiler based on the Microsoft Roslyn compiler platform and drawing from our popular Phalanger project. It allows PHP to be executed within the .NET framework, thereby opening the door for PHP developers into the world of .NET – and vice versa.

Status and Compatibility

You can find an up-to-date status of the project in our Roadmap section. Please note that the status is dynamic; PeachPie is a work in progress, which means that the list of finished and planned features frequently changes and will be updated on a regular basis. To see the current status of compatibility with the PHP language, please refer to our Compatibility overview.

Project goals

  • Increased performance: PeachPie's extensive type analysis and the influence of Microsoft Roslyn should provide an improved performance of PHP applications and components.

  • Security: since programs run within the standardized and manageable .NET or .NET Core environment, the code is fully verifiable without any unsafe constructs. In addition, PHP applications can be distributed source-lessly for added security benefits.

  • Cross-platform development: the project compiles legacy PHP code into portable class libraries, enabling developers to build cross-platform apps and libraries for Microsoft platforms.

  • Full .NET compatibility: compiled programs run on the reimplemented PeachPie runtime, fully compatibly with the PHP runtime.

  • Both-way interoperability: the project allows for hybrid applications, where parts are written in C# and others in PHP. The parts will be entirely compatible and can communicate seamlessly, all within the .NET framework.

How to use PeachPie

There are currently two ways of using PeachPie through msbuild: in your favorite shell or in Visual Studio Code/Visual Studio 2017. Keep in mind that PeachPie is still a work in progress and we therefore recommend thorough testing before running PeachPie-powered apps in a production environment.

Visual Studio Code

We have a custom VSCode extension to make working with PeachPie compiler as comfortable as possible. The extension automatically installs all required dependencies, enables the PeachPie: Create project command, syntax error underlining and PeachPie analytics:

Peachpie Extension

To install the PeachPie extension, simply launch VS Code Quick Open (Ctrl+P), paste the following command, and press enter: ext install peachpie-vscode. Watch the intro video to see how to work with the extension.

Command line building

Alternatively, you can also work with PeachPie on the command line. Please refer to our short introduction video to see how to run the compiler on the command line and to the Getting Started section in our documentation.
