wasmer-php's Introduction

Wasmer PHP

Website • Docs • Slack Channel

A complete and mature WebAssembly runtime for PHP based on Wasmer.

Features

Easy to use: The wasmer API mimics the standard WebAssembly C API,
Fast: wasmer executes the WebAssembly modules as fast as possible, close to native speed,
Safe: All calls to WebAssembly will be fast, but more importantly, completely safe and sandboxed.

Install

To install the library, follow the classical:

git clone https://github.com/wasmerio/wasmer-php
cd wasmer-php/ext
phpize
./configure --enable-wasmer
make
make test
make install

Note: Wasmer doesn't work on Windows yet.

Examples

Procedural API

<?php 

declare(strict_types=1);

$engine = wasm_engine_new();
$store = wasm_store_new($engine);
$wasm = file_get_contents(__DIR__ . DIRECTORY_SEPARATOR . 'hello.wasm');
$module = wasm_module_new($store, $wasm);

function hello_callback() {
    echo 'Calling back...' . PHP_EOL;
    echo '> Hello World!' . PHP_EOL;

    return null;
}

$functype = wasm_functype_new(new Wasm\Vec\ValType(), new Wasm\Vec\ValType());
$func = wasm_func_new($store, $functype, 'hello_callback');
wasm_functype_delete($functype);

$extern = wasm_func_as_extern($func);
$externs = new Wasm\Vec\Extern([$extern]);
$instance = wasm_instance_new($store, $module, $externs);

wasm_func_delete($func);

$exports = wasm_instance_exports($instance);
$run = wasm_extern_as_func($exports[0]);

wasm_module_delete($module);
wasm_instance_delete($instance);

$results = wasm_func_call($run, new Wasm\Vec\Val());

wasm_store_delete($store);
wasm_engine_delete($engine);

Object-oriented API

<?php

declare(strict_types=1);

use Wasm;

require_once __DIR__.'/../vendor/autoload.php';

$engine = Wasm\Engine::new();
$store = Wasm\Store::new($engine);

$wasm = file_get_contents(__DIR__.DIRECTORY_SEPARATOR.'hello.wasm');

$module = Wasm\Module::new($store, $wasm);

function hello_callback()
{
    echo 'Calling back...'.PHP_EOL;
    echo '> Hello World!'.PHP_EOL;

    return null;
}

$functype = Wasm\Functype::new(new Wasm\Vec\ValType(), new Wasm\Vec\ValType());
$func = Wasm\Module\Func::new($store, $functype, 'hello_callback');

$extern = $func->asExtern();
$externs = new Wasm\Vec\Extern([$extern->inner()]);
$instance = Wasm\Module\Instance::new($store, $module, $externs);

$exports = $instance->exports();
$run = $exports[0]->asFunc();

$args = new Wasm\Vec\Val();
$results = $run($args);

This example covers the most basic Wasm use case: we take a Wasm module (in its text representation form), create an instance from it, get an exported function and run it.

How to set parameter type to i64 in imported functions

Hi,
i try to implement missing function where expected signature is:
expected signature: [I32, I64, I32, I32] -> [I32]

my code:

$imports = [
    'wasi_unstable' => [
	'fd_seek' => function(int $file, int $offset, int $whence, int $newoffset): int {
	    return 0;
	},
   ]
]

$instance = new Wasm\Instance(__DIR__ . '/demo.wasm', $imports);

when i try to run i get this error:
Incorrect import signature, namespace: wasi_unstable, name: fd_seek, expected signature: [I32, I64, I32, I32] -> [I32], found signature: [I32, I32, I32, I32] -> [I32]

How to set parameter type to i64 in imported functions?

WASI support

Hello 👋 , quick question :)

According to this article - https://hacks.mozilla.org/2019/03/standardizing-wasi-a-webassembly-system-interface/ one is able to just run WASM binary that was compiled with WASI support (it's possible that I mix terms, sorry)

I've found somewhere on Twitter, that PHP is not yet supported by https://github.com/CraneStation/wasmtime.

But what if I'm gonna use this extension, which uses Wasmer, which has support for WASI, it's gonna work right 🙏?

Thanks for your time.

Windows build

Has anyone succeeded in building it for Windows? I have VC++ 2017 and what I did was:

Downloaded the SDK tools for PHP 7.1
Ran phpize.bat in the src folder to generate configure.bat
Ran configure.bat
Ran nmake, but got I lot of compilation errors like:

...\src\wasm.cc(124): warning C4003: not enough arguments for function-like macro invocation 'ZEND_BEGIN_ARG_WITH_RETURN_TYPE_INFO_EX'
...\src\wasm.cc(124): error C2059: syntax error: ','
...\src\wasm.cc(124): error C2143: syntax error: missing ';' before '}'
...\src\wasm.cc(124): error C2059: syntax error: '}'
...\src\wasm.cc(125): error C2059: syntax error: '}'
...\src\wasm.cc(125): error C2143: syntax error: missing ';'

I tried adding /std:c++14 to the cl.exe args, but to no avail. Any tips would be appreciated :)

Will it be possible to serialize state and limit execution time?

Summary

Will this extension support non-blocking operation and state serialization?

Additional details

It can in many cases be helpful to run code for a certain number of instructions, or milliseconds before execution is preemptively halted.

This can be useful for example in event loop environments such as swoole or ReactPHP.

To support this, it would be necessary that wasm methods could return a special "WasmHalted" object. This object could represent that execution was halted due to timeout, waiting for IO, or it could represent a request for opening a resource such as a file.

$delayed = $instance->sum(1, 2);

$delayed->run(1000); // 1000 instructions
$s = serialize($delayed);

$delayed = $instance->resume(unserialize($s)) ;

while(!$delayed->done()) {
    $delayed->run(1000):
} 
$delayed->result(); // done

I would love if this object could be serialized and resumed. Sure, the serialized object can become quite large, if the wasm binary uses a lot of memory but that would be my problem.

Supported types

Hey,

Thanks for your awesome work. :-)

Where can I find the supported types between PHP and WASM?
For example, I want to see if a wasm function can return a PHP associative array or not.

Would I be able to use golang to produce the wasm file?

Summary

Is it possible to use this project to load a wasm file generated from golang?

Additional details

I tried but got

Publish the Kitab documentation on the Github pages

Kitab is used to document and test our API. We need to publish the documentation online, on a Github pages for instance.

Dependabot couldn't find a Cargo.toml for this project

Dependabot couldn't find a Cargo.toml for this project.

Dependabot requires a Cargo.toml to evaluate your project's current Rust dependencies. It had expected to find one at the path: /Cargo.toml.

If this isn't a Rust project, or if it is a library, you may wish to disable updates for it from within Dependabot.

Implement a cache to not compile the Wasm module everytime

The idea is basically to add a cache, so that we don't have to validate & compile etc. the whole module everytime. It will improve grately the execution speed.

There is no API in wasmer-runtime-c-api yet. I need to work on that. Maybe we will implement that outside the wasmer-runtime-c-api crate.

maybe we should have a docker environment

Possibility to integrate Rust Cassandra client into PHP

Hello,

Recently, I have faced a problem that official PHP Cassandra Client isn't maintained well and does not support PHP >=7.3. The idea might sound crazy but still. Is it possible to compile https://crates.io/crates/cdrs into WASM binary, use inside PHP and rely on such client on production? Also, what is the cost and limitations of using php-ext-wasm?

Thanks in advance!

Cargo dependencies of an example

Summary

Hello 👋
I would like to compile an example with serde crate.

Additional details

I've tried following:

serde = { version = "1.0", features = ["derive"] }
serde_json = "1.0"

into Cargo.toml
2. Run cargo build
3. Run just compile-wasm examples/greet

Modified verison of greet.rs

use std::ffi::{CStr, CString};
use std::mem;
use std::borrow::Cow;
use std::os::raw::{c_char, c_void};
use serde::{Serialize, Deserialize};

#[derive(Serialize, Deserialize, Debug)]
struct Subject<'a> {
    subject: Cow<'a, str>,
}

#[no_mangle]
pub extern fn allocate(size: usize) -> *mut c_void {
    let mut buffer = Vec::with_capacity(size);
    let pointer = buffer.as_mut_ptr();
    mem::forget(buffer);

    pointer as *mut c_void
}

#[no_mangle]
pub extern fn deallocate(pointer: *mut c_void, capacity: usize) {
    unsafe {
        let _ = Vec::from_raw_parts(pointer, 0, capacity);
    }
}

#[no_mangle]
pub extern fn greet(subject: *mut c_char) -> *mut c_char {
    let subject = unsafe { CStr::from_ptr(subject).to_string_lossy() };
    let point = Subject { subject };

    let serialized = serde_json::to_string(&point).unwrap();
    println!("serialized = {}", serialized);
    unsafe { CString::from_vec_unchecked(serialized.as_bytes().to_vec()) }.into_raw()
}

But I've got only errors:

error[E0432]: unresolved import `serde`
 --> examples/greet.rs:5:5
  |
5 | use serde::{Serialize, Deserialize};
  |     ^^^^^ maybe a missing `extern crate serde;`?

  |
7 | #[derive(Serialize, Deserialize, Debug)]
  |                     ^^^^^^^^^^^
  |
  = note: import resolution is stuck, try simplifying macro imports

error: cannot determine resolution for the derive macro `Serialize`
 --> examples/greet.rs:7:10
  |
7 | #[derive(Serialize, Deserialize, Debug)]
  |          ^^^^^^^^^

  --> examples/greet.rs:33:22
   |

   |                      ^^^^^^^^^^ use of undeclared type or module `serde_json`

error: aborting due to 4 previous errors

Some errors have detailed explanations: E0432, E0433.
For more information about an error, try `rustc --explain E0432`.
error: Recipe `compile-wasm` failed with exit code 1

But I've found a solution, but I do not like it.

Create Cargo.toml in examples folder

[package]
publish = false
name = "php-wasm-greet"
version = "1.0.0"
edition = "2018"

[lib]
path = "greet.rs"
crate-type = ["cdylib"]

[dependencies]
serde = { version = "1.0", features = ["derive"] }
serde_json = "1.0"

Create new just recipe

compile-and-run-example FILE='greet':
	#!/usr/bin/env bash
	set -euo pipefail
	cd examples
	cargo +nightly build --target wasm32-unknown-unknown
	cp target/wasm32-unknown-unknown/debug/php_wasm_{{FILE}}.wasm {{FILE}}.wasm
	php -d extension=wasm {{FILE}}.php

Run just compile-and-run-example greet

There is surely better way. Could you give me an advice?

:pray Thanks in advance!

Implement `wasm_memory_*`

We need an API to grow memory, add pages etc.

Release on PECL?

Once this is no longer experimental (starting to look good with #4 being done!!), should this be put on PECL for easy installation?

add wasm3 backend support

Motivation

The default backend build size is huge, can we add https://github.com/wasm3/wasm3 as alternative backend choice to reduce the binary size ?

Implement `wasm_compile` and `wasm_module_instantiate`

Because it'll be fun!

Update to Wasmer 0.4.0

See https://github.com/wasmerio/wasmer/releases/tag/0.4.0.

Get persistent modules or instances

As discussed in #26 (comment), it would be great to be able to get persistent modules or instances between PHP requests.

Cannot address by function name

I'm having some trouble with trying to make a sensible interface to actually using this library, but I may just be missing something obvious (or, alternatively, have completely missed a key paradigm :P)

Looking at your example copy of your exports-function.php example, we see that although we have an exported function of "sum", it only ever gets referenced by $exports->offsetGet(0), not by Sum.

Compiling the most barebones addition rust program, I end up with something like this:

(module
  (type $t0 (func (param i32) (result i32)))
  (func $add_one (export "add_one") (type $t0) (param $p0 i32) (result i32)
    (i32.add
      (local.get $p0)
      (i32.const 1)))
  (memory $memory (export "memory") 16)
  (global $__data_end (export "__data_end") i32 (i32.const 1048576))
  (global $__heap_base (export "__heap_base") i32 (i32.const 1048576)))

The only way I can find to reference that function is like so: $addOne = (new Wasm\Extern($exports->offsetGet(1)))->asFunc();

There doesn't seem to be an getByName or similar.

I can iterate through the exports and filter it down to the exports that are only functions, but I haven't had any success at finding any method that will then translate that function to what it's name is.

Thank you!

Waht is the mini PHP version requirement?

Summary

I am trying to build the PHP extension of PHP version:

PHP 7.1.16-1+b1 (cli) (built: May 12 2018 08:31:35) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.1.0, Copyright (c) 1998-2018 Zend Technologies
    with Zend OPcache v7.1.16-1+b1, Copyright (c) 1999-2018, by Zend Technologies
    with Xdebug v2.6.0, Copyright (c) 2002-2018, by Derick Rethans

on Linux.

But some build errors occur:

/tmp/php-ext-wasm-0.5.0/src/wasm.cc:123:132: error: macro "ZEND_BEGIN_ARG_WITH_RETURN_TYPE_INFO_EX" requires 6 arguments, but only 5 given
 ZEND_BEGIN_ARG_WITH_RETURN_TYPE_INFO_EX(arginfo_wasmarraybuffer_get_byte_length, ZEND_RETURN_VALUE, ARITY(0), IS_LONG, NOT_NULLABLE)

/tmp/php-ext-wasm-0.5.0/src/wasm.cc:123:1: error: ‘ZEND_BEGIN_ARG_WITH_RETURN_TYPE_INFO_EX’ does not name a type
 ZEND_BEGIN_ARG_WITH_RETURN_TYPE_INFO_EX(arginfo_wasmarraybuffer_get_byte_length, ZEND_RETURN_VALUE, ARITY(0), IS_LONG, NOT_NULLABLE

Implement `wasm_validate`

Because it will be cool :-).

Go wasm not supported ?

Summary

I compiled a simple wasm instance with go, but it has exceptions.

Fatal error: Uncaught RuntimeException: An error happened while compiling or instantiating the module `/Users/mac-mini/go/src/demo/9/go_main.wasm`:

libtool version is 2.4.6_2 on mac and 2.4.6-0.1 on Linux.

Sample output from a Linux build but I get the same errors on mac.

How to use with wasm-pack?

I have a small test project and use wasm-pack --target web to expose it to the browser. Is it possible ot use wasm-pack instead of just compile-wasm to generate a wasm that this PHP extension can read?

Pass string to wasm function

Hi, I think the project looks really great. How would you pass a string to a function defined in wasm. The memory example shows how you could return a string from a function. I would assume that we could also create a Uint8Array and pass this containing the string bytes to the wasm function? In this case we could probably create in this lib some helper functions i.e. to convert a string to Uint8Array. Also Iam curious whether it would be possible to pass more complex data structures like assoc array (struct) to a wasm function?

Support PHP 7.2

Summary

What's the PHP version?

Hello~ My PHP version is PHP 7.2.18 in CentOS 7.2. I haven't found it in the doc.
When I build it, it replies to some error.

I don't know what went wrong
Providing a Dockerfile might be a better option

Update to wasmer 0.3.0.

New release of wasmer, we must support it.

Install a CI

Because we need it.

chore(runtime) Update Wasmer to 0.4.2

Because it must be done.

Compile failed in different situation

Hi, thanks for this great library, I saw multiple changes and try to build on my computer. But got different errors:

`./configure --enable-wasmer'

--enable-wasmer options not found

After checkout configure file, does it be --enable-wasm?

make succeed, but the make test didn't work:

PHP 7.4.10 (cli) (built: Sep 9 2020 06:36:14) ( NTS )

If I did some significant work on this repo (touching almost every file), would you merge it?

I would like to rework this repository into something more widely usable in the PHP community. Here are a few things that I've noticed:

A PHP extension is required to do anything. This is probably the single biggest thing blocking wide adoption of this library. The vast majority of PHP applications are hosted on shared hosting providers that don't allow installing/loading additional PHP extensions. Even for the ones that are hosted on e.g. a VPS or whatever, installing some random PHP extension is not a common thing.
Because the extension exposes the wasmer engine as a resource in PHP, it's impossible to write a pure PHP polyfill that would e.g. use FFI or similar to get the same functionality. It's not possible to create a new resource type directly in PHP and it is also not possible to pretend that an object is an instance of a particular resource type, so even if I write a class that has the same interface as your resource, I still can't pass it in as an argument to the constructor of e.g. \Wasm\Module. There are a couple of libraries that I'm aware of that rely on an extension, but have a pure PHP implementation as a fallback -- even if that's just via FFI. FFI is a relatively new thing to PHP, but I think it's still a viable path for people using PHP 7.4 or higher.
Because many of the classes are final, I also can't extend the class and make the changes that I need to make in order to support the above on my own.
Details about the wasmer engine need to be known to the developer in order to effectively use this library. I'm not sure that this is actually based on any real technical requirement though -- it should be possible to expose a limited but very straightforward interface to developers that encapsulates those details. As a very simple example, maybe something along the lines of:

// file.wasm exports add and multiply functions and a myval value
$wasm = \Wasm::load('/path/to/my/file.wasm');

echo($wasm->add(1, 2));
echo($wasm->multiple(2, 4));
echo($wasm->myval);

This would more or less be a 2.x version of this library (I'm not sure how you'd do this without a BC break). Maybe it's of interest?

Compilation issue on ppa:ondrej/php

Hi,

I'm very excited about the possibilities for this extension!!! :-)

Describe the bug

Should I build against staging branch? When I built against master it didn't complete.

Steps to reproduce

Followed installation instructions in README for staging branch

Expected behavior

php examples/simple.php didn't run

Is it possible to write to WebAssembly.Memory in PHP that is exported to and read in JavaScript in parallel?

Summary

Consider

<?php 
  if (isset($_GET["start"])) {
    header("Access-Control-Allow-Origin: *");
    header("Content-Type: application/octet-stream");
    echo passthru("parec -v --raw -d alsa_output.pci-0000_00_1b.0.analog-stereo.monitor");
    exit();
  }

where due to Chromium refusing to capture monitor devices when getUserMedia({audio: true}) is executed at Linux we use
php -S localhost:8000 to stream output of passthru() to Response.body (ReadableStream) from fetch() call.

let controller, signal;
const [start, stop] = document.querySelectorAll('button');
start.onclick = async e => {
  start.disabled = true;
  // set parameters as arrays for potential "infinite" input, output stream
  let { track, port } = await new AudioWorkletStream({
    latencyHint: 1,
    workletOptions: {
      numberOfInputs: 1,
      numberOfOutputs: 2,
      channelCount: 2,
      processorOptions: {
        codec: 'audio/wav',
        offset: 0,
      },
    },
  }).promise;

  console.log(track, port);
  controller = new AbortController();
  signal = controller.signal;
  fetch('http://localhost:8000?start=true', { signal })
    .then(r => r.body)
    .then(readable => {
      const reader = readable.getReader();
      reader
        .read()
        .then(function process({ value, done }) {
          if (done) {
            console.log(done);
            return;
          }
          console.log(value);
          return reader.read().then(process);
        })
        .catch(console.error);
    });
};
stop.onclick = e => {
  controller.abort();
};

Ideally we should be able to write the output from the shell script directly to a WebAssembly Memory instance, grow the shared array buffer if necessary, export that same Memory instance to JavaScript for the purpose of reading the shared memory in parallel to writing to and possible growing the single buffer, in this case, to stream audio in "real-time" using AudioWorklet, and finally flush the buffer once the stream closes.

Is this possible using the code in this repository?

How should call a function from php?

For javascript, wasm can do interaction with js function by some approaches. Can php-ext-wasm do it too ?

Capabilities of wasm?

Hi, I have a quick question. Is it possible to implement new language construct for php via wasm, say I want to write a jsx like preprocessor that can return xml like syntax from a method or function body directly in the php file.

Does wasm provides same level capability with php or zend extensions? If I understood correctly, wasm modules can be an be packaged with Composer and does not require additional step like zend extensions, which makes it perfect for distribution. Thanks.

Edit: A WebAssembly binary has no access to the PHP environment (so no access to its memory or functions). It is executed in a sandbox.
