ππΈοΈ WebAssembly runtime for PHP
License: MIT License
Languages: C, M4, PHP, C++, CMake, Makefile, WebAssembly
A complete and mature WebAssembly runtime for PHP based on Wasmer.
wasmer
API mimics the standard WebAssembly C API,wasmer
executes the WebAssembly modules as fast as possible, close to native speed,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.
<?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);
<?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.
