Calling a function from inside $pool->add?

[carys-cc]

This might be a really silly question. I'm kind of new to PHP.

I have a function called test() that just takes the object $thing and does addition.
However when I run this, nothing is output.

Seems like functions are not available inside the pool->add function?

use Spatie\Async\Pool;

$pool = Pool::create();

foreach ($things as $thing) {
    $thing->a = 1;
    $thing->b = 2;

    $pool->add(function () use ($thing) {
        // Do a thing
        return test($thing);           // ***** is this even being called?
    })->then(function ($output) {
        // Handle success
 
        echo $output;           // ***** nothing happens here
    })->catch(function (Throwable $exception) {
        // Handle exception
    });
}

$pool->wait();


//     *** just a simple addition function
function test($thing) {
  return $thing->a + $thing->b;
}

No functions are not magically moved around, you need to load all your required functions via a custom autoloader, then it will work.
