Embed your code¶

PHP has a filesystem of its own, in memory: it does not see your disk. It runs what the page writes in it (php.FS.writeFile()), and what is embedded in the .wasm file when it is built. node node/run.mjs my-script.php runs a file of your disk: run.mjs copies it in the filesystem of PHP first.

To embed a directory, my-app/ here, at /app:

docker buildx bake --set default.contexts.embed=./my-app --set default.args.EMBED_AT=/app
node node/run.mjs -r 'require "/app/index.php";'

/app/index.php is the copy that was embedded: it only changes with a new build. A page runs it with php.runFile('/app/index.php').

To do the same from a project of yours, with its dependencies: see Use it in your project.
