Run PHP script in Node.js (or CMD)?

Question

Due to some reasons in need to run a small part of my NodeJS Project in PHP7. I know I can make an internal API but that would increase network dependency.

To solve this problem I found that this can be done as

php test.php

How do I provide a JSON input to this PHP file where data is stored in a JS variable not in file and receive output in another JS variable.

function runPHP(jsonString){
    ....what to write here
    ...
    return output_string;
}

Note: Please, do not suggest Query parameters as the data is too large.

I assume you want to call a php scipt from a nodejs process, send some arguments in JSON and get back some JSON and process it further.

The php script:

<?php
// test.php
$stdin = fopen('php://stdin', 'r');

$json = '';

while ($line = fgets($stdin)) {
    $json .= $line;
}

$decoded = \json_decode($json);

$decoded->return_message = 'Hello from PHP';

print \json_encode($decoded);

exit(0);

The nodejs script:

// test.js
function runPHP(jsonString) {
  const spawn = require('child_process').spawn;
  const child = spawn('php', ['test.php']);

  child.stdin.setEncoding('utf-8');
  child.stdout.pipe(process.stdout);

  child.stdin.write(jsonString + '\n');

  child.stdin.end();
}

runPHP('{"message": "hello from js"}');

This will need some polishing and error handling...
