Bindings and abstractions for the Zend API to build PHP extensions natively in
|
|
Rust.
|
|
|
|
- Documentation: <https://docs.rs/ext-php-rs>
|
|
- Guide: <https://davidcole1340.github.io/ext-php-rs>
|
|
|
|
## Example
|
|
|
|
Export a simple function `function hello_world(string $name): string` to PHP:
|
|
|
|
```rust
|
|
#![cfg_attr(windows, feature(abi_vectorcall))]
|
|
|
|
use ext_php_rs::prelude::*;
|
|
|
|
/// Gives you a nice greeting!
|
|
///
|
|
/// @param string $name Your name.
|
|
///
|
|
/// @return string Nice greeting!
|
|
#[php_function]
|
|
pub fn hello_world(name: String) -> String {
|
|
format!("Hello, {}!", name)
|
|
}
|
|
|
|
// Required to register the extension with PHP.
|
|
#[php_module]
|
|
pub fn module(module: ModuleBuilder) -> ModuleBuilder {
|
|
module
|
|
}
|
|
```
|
|
|
|
Use [`cargo-php`] to build IDE stubs and install the extension:
|
|
|
|
```text
|
|
$ cargo install cargo-php
|
|
Installing cargo-php v0.1.0
|
|
$ cargo php stubs --stdout
|
|
Compiling example-ext v0.1.0
|
|
Finished dev [unoptimized + debuginfo] target(s) in 3.57s
|
|
<?php
|
|
|
|
// Stubs for example-ext
|
|
|
|
/**
|
|
* Gives you a nice greeting!
|
|
*
|
|
* @param string $name Your name.
|
|
*
|
|
* @return string Nice greeting!
|
|
*/
|
|
function hello_world(string $name): string {}
|
|
$ cargo php install --release
|
|
Compiling example-ext v0.1.0
|
|
Finished release [optimized] target(s) in 1.68s
|
|
Are you sure you want to install the extension `example-ext`? yes
|
|
$ php -m
|
|
[PHP Modules]
|
|
// ...
|
|
example-ext
|
|
// ...
|
|
```
|
|
|
|
Calling the function from PHP:
|
|
|
|
```php
|
|
var_dump(hello_world("David")); // string(13) "Hello, David!"
|
|
```
|
|
|
|

|
## Features
|
|
|
|
- **Easy to use:** The built-in macros can abstract away the need to interact
|
|
with the Zend API, such as Rust-type function parameter abstracting away
|
|
interacting with Zend values.
|
|
- **Lightweight:** You don't have to use the built-in helper macros. It's
|
|
possible to write your own glue code around your own functions.
|
|
- **Extensible:** Implement `IntoZval` and `FromZval` for your own custom types,
|
|
allowing the type to be used as function parameters and return types.
|
|
|
|
## Goals
|
|
|
|
Our main goal is to **make extension development easier.**
|
|
|
|
- Writing extensions in C can be tedious, and with the Zend APIs limited
|
|
documentation can be intimidating.
|
|
- Rust's modern language features and feature-full standard library are big
|
|
improvements on C.
|
|
- Abstracting away the raw Zend APIs allows extensions to be developed faster
|
|
and with more confidence.
|
|
- Abstractions also allow us to support future (and potentially past) versions
|
|
of PHP without significant changes to extension code.
|
|
|
|
## Documentation
|
|
|
|
The library guide can be read
|
|
[here](https://davidcole1340.github.io/ext-php-rs).
|
|
|
|
The project is documented in-line, so viewing the `cargo` documentation is the
|
|
best resource at the moment. This can be viewed at [docs.rs].
|
|
|
|
## Requirements
|
|
|
|
- Linux, macOS or Windows-based operating system.
|
|
- PHP 8.0 or later.
|
|
- No support is planned for earlier versions of PHP.
|
|
- Rust.
|
|
- Currently, we maintain no guarantee of a MSRV, however lib.rs suggests Rust
|
|
1.57 at the time of writing.
|
|
- Clang 5.0 or later.
|
|
|
|
### Windows Requirements
|
|
|
|
- Extensions can only be compiled for PHP installations sourced from
|
|
<https://windows.php.net>. Support is planned for other installations
|
|
eventually.
|
|
- Rust nightly is required for Windows. This is due to the [vectorcall] calling
|
|
convention being used by some PHP functions on Windows, which is only
|
|
available as a nightly unstable feature in Rust.
|
|
- It is suggested to use the `rust-lld` linker to link your extension. The MSVC
|
|
linker (`link.exe`) is supported however you may run into issues if the linker
|
|
version is not supported by your PHP installation. You can use the `rust-lld`
|
|
linker by creating a `.cargo\config.toml` file with the following content:
|
|
```toml
|
|
# Replace target triple if you have a different architecture than x86_64
|
|
[target.x86_64-pc-windows-msvc]
|
|
linker = "rust-lld"
|
|
```
|
|
- The `cc` crate requires `cl.exe` to be present on your system. This is usually
|
|
bundled with Microsoft Visual Studio.
|
|
- `cargo-php`'s stub generation feature does not work on Windows. Rewriting this
|
|
functionality to be cross-platform is on the roadmap.

|
|
|
|
## Cargo Features
|
|
|
|
All features are disabled by default.
|
|
|
|
- `closure` - Enables the ability to return Rust closures to PHP. Creates a new
|
|
class type, `RustClosure`.
|
|
- `anyhow` - Implements `Into<PhpException>` for `anyhow::Error`, allowing you
|
|
to return anyhow results from PHP functions. Supports anyhow v1.x.
|
|
|
|
