Run it in a page¶

php-web.mjs is a module, that a page imports. Save this page as build/php-8.5/index.html, next to it:

<pre id="output"></pre>
<script type="module">
    import createPhp from './php-web.mjs';

    const php = await createPhp();
    const { stdout } = await php.runCode('echo "Hello from PHP ", PHP_VERSION;');

    document.getElementById('output').textContent = stdout;
</script>

A browser does not load a module from a file: URL, so the directory must be served. Any static server does it, the one of PHP for example:

php -S 127.0.0.1:8000 -t build/php-8.5

Then open http://127.0.0.1:8000/.

What else the page can do is in JavaScript API.
