php example (x86_64)

Convert to WASI

Convert the php image to WASM

$ c2w php:8.1-cli-alpine3.16 /tmp/out/out.wasm

Run it on the runtime:

$ wasmtime -- /tmp/out/out.wasm -- -r 'print("hello world\n");'
hello world

This passes -r 'print("hello world\n");'" argument to php (entrypoint of this image) and hello world is printed.

Run WASI image on browser

The following runs the WASI-converted container image on browser.

Run this at the project repo root directory.

$ c2w php:8.1-cli-alpine3.16 /tmp/out-js2/htdocs/out.wasm
$ cp -R ./examples/wasi-browser/* /tmp/out-js2/ && chmod 755 /tmp/out-js2/htdocs
$ docker run --rm -p 8080:80 \
         -v "/tmp/out-js2/htdocs:/usr/local/apache2/htdocs/:ro" \
         -v "/tmp/out-js2/xterm-pty.conf:/usr/local/apache2/conf/extra/xterm-pty.conf:ro" \
         --entrypoint=/bin/sh httpd -c 'echo "Include conf/extra/xterm-pty.conf" >> /usr/local/apache2/conf/httpd.conf && httpd-foreground'

You can run the container on browser via localhost:8080.

PHP REPL will start on browser (you might need to wait a while untils the prompt is printed).

Please see wasi-browser example for details about WASI-on-browser.

Run on browser using emscripten

$ c2w --to-js php:8.1-cli-alpine3.16 /tmp/phpjs/htdocs/

Run it on browser:

Run this at the project repo root directory.

$ cp -R ./examples/emscripten/* /tmp/phpjs/ && chmod 755 /tmp/phpjs/htdocs
$ docker run --rm -p 8080:80 \
         -v "/tmp/phpjs/htdocs:/usr/local/apache2/htdocs/:ro" \
         -v "/tmp/phpjs/xterm-pty.conf:/usr/local/apache2/conf/extra/xterm-pty.conf:ro" \
         --entrypoint=/bin/sh httpd -c 'echo "Include conf/extra/xterm-pty.conf" >> /usr/local/apache2/conf/httpd.conf && httpd-foreground'
