Cannot assign value to array using PHP pthreads

Question

I have the following code where I'm attempting to assign a value to an array in a class that uses php pthreads to no avail - I have looked at solutions that suggest using stacks to no avail either:

<?php
ini_set('display_errors',1);
ini_set('display_startup_errors',1);
error_reporting(E_ALL);

    class WorkerThreads extends Thread
        {
            private $fromlist;

            public function __construct()
            {
                    $this->fromlist = array();
            }

            public function run()
            {
                   $this->fromlist=array("hello"=>1,2);
                   $this->fromlist['hi']="!!!";
                   $this->fromlist[] = array("ho", 1);
            }
        }

            $workers = new WorkerThreads();
            $workers->start();
            print_r($workers);

I get the following results:

WorkerThreads Object
(
    [fromlist] => Array
        (
            [hello] => 1
            [0] => 2
        )

)

I was expecting to see additional array elements - try as I may I cannot get it to add more elements.

I've checked the syntax and it seems fine - the problem appears to be how to use an array in pthreads - I can't seem to make sense of how to do that.

Can anyone tell me what I'm doing wrong?

Or suggest some code for the above so I can get to a working solution?

Answer 1

Adding the $fromlist variable to the run() function solves the problem.
