README

Builds PHP as WebAssembly, for the browser and for node, with the PHP version and the extensions you ask for, and the code you embed.

• The documentation: https://lyrixx.github.io/php-wasm-builder/, from docs/.
• The examples, that run in your browser: https://lyrixx.github.io/php-wasm-builder/#examples.

Try it

Docker builds PHP in build/php-8.5/, node runs it:

docker buildx bake
node node/run.mjs -r 'echo "Hello from PHP ", PHP_VERSION, "\n";'

A page imports php-web.mjs, and runs PHP:

<script type="module">
    import createPhp from './build/php-8.5/php-web.mjs';

    const php = await createPhp();
    const { stdout } = await php.runCode('echo PHP_VERSION;');
</script>

To build PHP for a page of your own, with your code, from your project: see Use it in your project.

Where things are

• docker/: the Dockerfile that compiles PHP, and the JavaScript API of what it builds;
• stacks.php: the builds that this repository checks, in CI too;
• examples/: the examples of the website, a directory each, laid out as a project of your own would be: stack.php, public/, and app/;
• docs/ and zensical.toml: the documentation, and the website;
• CHANGELOG.md: what changes, that the website shows too;
• castor.php and src/: the tasks that build, check and serve all of it, castor list lists them;
• node/ and tests/: what runs PHP in node, and tests it.

Credits

This builder was created by Derick Rethans, for The PHP Foundation, in derickr/php-wasm-builder, the builder of the PHP WASM files of the php.net documentation. What runs PHP, docker/run.c, comes from the work of Antoine Bluchet. Both are under the MIT license, see LICENSE. The documentation thanks everyone else, see Credits.
