## What it is
PeachPie is an open-source PHP compiler built on Microsoft Roslyn that compiles PHP code to .NET and .NET Core, with a reimplemented PHP runtime for full compatibility. It enables both-way PHP/.NET interoperability, letting hybrid applications mix C# and PHP seamlessly.

## Use cases
- compile php code to .net
- run php applications on .net core
- call php classes from c#
- migrate legacy php codebase to dotnet
- distribute php apps as nuget packages without source
- build hybrid c# and php projects in one solution

## When to choose
- you need PHP and .NET code to interoperate in a single application
- you want to run PHP on the cross-platform, verifiable .NET runtime
- you want to distribute PHP applications source-lessly as .NET libraries
- you want static analysis and diagnostics for PHP at compile time

## When to avoid
- you need a standard LAMP stack or PHP extensions not reimplemented by the runtime
- your project depends on the latest PHP version features
- you only need to host PHP scripts without .NET integration
