accessing values from php array

Question

I have been having an issue getting values out of an array that is formatted like so:

array(
   [key]=>array(
            [0]=>value
            [1]=>value
            [2]=>value)
   [key]=>array(
            [0]=>value
            [1]=>value))

I am using a queue to run through each key as the queue item and process the information. so to create the queue item I have tried this:

while ($array = $result->fetchAssoc())
                {

                    $queue->createItem($array);

                }

this fails to create any items so I have used this method instead

if ($array != 0 || $array != NULL) {
       foreach ($array as $row) { 
            $queue->createItem($row);
       }
}

Once the queue item is created the queue calls a function passing the queue $item and here is where I have problems as I can successfully get all the values of the second level array but I can not access the Key of the first level.

function work_function($item){

   foreach($item as $row=>$job){
       //do something
   }
}

In my function I have tried:

 //1
    $arrayKEY= $item;

    //2
    foreach($item as $row){
     $arrayKEY= $row;
    }

I just cannot get the values I need. What am I doing wrong/can I do to accomplish this?

Thanks

@user975044. Any chance of the less prissy definition of $queue? Specifically which Php object is it? — CBusBus

Ok, specifically for my case i am using: api.drupal.org/api/drupal/modules--system--system.api.php/… terrible doc though.. Drupal i know.. but that shouldn't matter to the problem. A queue is basically a way of loading objects into a container or line to be processed. So if I want the number 1,2,3,4 to be processed in that order through the same function I can create a queue object for each number. so in the queue I have 4 objects which contain the numbers 1,2,3,4 in that order. — user975044

To start processing the queue the first object, which is number 1, gets pulled from the queue and processed. I shouldn't haven mentioned this as it really isn't causing the issue here. It is being able to access the array key and values in a function — user975044

@user975044: We all know what a queue is, we're asking you what your $queue object is, specifically. — gen_Eric

There's not much info here, but if the array is like you show, it's a multi-dimensional array, and thus needs 2 for loops.

function work_function($item){
   foreach($item as $row=>$job){
       echo "Row $row:\n";
       foreach($job as $value){
          echo $value."\n";
       }
   }
}
