symfony: Undefined constant AMQP_NOPARAM in AmqpStamp

Symfony version(s) affected

6.3.12

Description

I just tried to use this package symfony/amqp-messenger@6.3.12 last night and today noticed that I am receiving this exception:

"message": "Uncaught PHP Exception Error: \"Undefined constant \"AMQP_NOPARAM\"\" at /var/www/html/modeer-web-app/vendor/symfony/amqp-messenger/Transport/AmqpStamp.php line 27",
  "context": {
    "exception": {
      "class": "Error",
      "message": "Undefined constant \"AMQP_NOPARAM\"",
      "code": 0,
      "file": "/var/www/html/modeer-web-app/vendor/symfony/amqp-messenger/Transport/AmqpStamp.php:27"
    }
  },
  "level": 500,
  "level_name": "CRITICAL",
  "channel": "request",
  "datetime": "2024-04-20T17:02:33.166481+04:30",
  "extra": {}
}

And when I search for the definition of the constant AMQP_NOPARAM in vendor/symfony/amqp-messenger, it seems it is not defined. To do a workaround I created this file at scripts/amqp-constants.php:

<?php

if (!defined('AMQP_NOPARAM')) {
    define('AMQP_NOPARAM', 0);
}

and added the following to composer.json:

    "autoload": {
        "files": ["scripts/amqp-constants.php"],

But it does not really look the right thing for me, I must have been missing something or is it a bug?

How to reproduce

I mentioned all the code above.

Possible Solution

I added my workaround above, maybe it could also be moved to the repo itself?

I think he meant you should access it via web SAPI (via browser, curl, …) instead of CLI SAPI.

<?php

var_dump(AMQP_NOPARAM);
var_dump(phpversion('amqp'));

What is the output of this script when you access it over your web server?

Ubuntu ships the old v1 of the extension. I suspect that v1 does not have the constant (which is just an alias for zero anyway). So the fix might be that we’re using 0 instead of the constant in Symfony.
