Can't make @php-wasm/node PHP CLI work

[mho22]

Steps to reproduce quickly :

package.json

{
    "type": "module",
    "scripts": {
        "php": "node wasm.js"
    },
    "dependencies": {
        "@php-wasm/node": "^0.5.2"
    },
    "stackblitz": {
        "startCommand": "npm run php test.php"
    }
}

wasm.js

import { NodePHP } from '@php-wasm/node';

const php = await NodePHP.load( '8.2' );

php.cli( [ 'php', ...process.argv.slice( 2 ) ] );

test.php

<?php

echo 'Hello World!';

run npm run php test.php

> php
> node wasm.js test.php

Could not open input file: test.php


  WASM ERROR
  Program terminated with exit(1)

I can't figure out what I did wrong...

@mho22 The WASM ERROR message is very misleading, it just indicated that PHP terminated. What you're missing is a call to php.useHostFilesystem(); that would make that file visible to PHP. I like using @php-wasm/cli package where that's already taken care of. You can use it through npx or inside the repo like this:

; TMPDIR=`pwd`/tmp PHP=8.2 nx start php-wasm-cli  ./test.php
Hello World!

The TMPDIR env variable is related to #828.

I'll close the discussion for now, but feel free to reopen if this doesn't address your question.

I am sorry I found out why it didn't work and I forgot to delete this discussion. I used php.mount() and it worked as expected.
