Trigger a Node.js event from PHP

Question

Trigger a Node.js event from PHP

I have a PHP script running and supposedly I'd like to trigger Node.js firing an event to the client side when certain PHP logic has been fulfilled, how should I do it? The Node.js part is still yet to be set up, but will probably be on a different server other than the PHP/Apache one, and being put behind an Nginx which functions as a reverse proxy.

php
javascript
apache
node.js
nginx

Try:

<?php

$ch = curl_init();

$data = array('name' => 'Foo', 'file' => '@/home/user/test.png');

curl_setopt($ch, CURLOPT_URL, 'http://localhost:8000/'); /* Node app*/
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

curl_exec($ch);
?>

You can connect with your php server to a node.js server, yes.

See the NodeLog Class on this page as an example,

It's just a socket at the end of the day.
