PHP: How to implode these array values?

Question

I have these code:

 $arr = array($check);

When I try to

 echo "<pre>"; 
 die(print_r($arr));

it gives me result in the Firebug

 <pre>Array
          (
            [0] => Array
             (
               [0] => 2
               [1] => 1
             )

           )

Now, I want an output that will give me '2,1'. How could I do that in PHP? Do I need to use implode?

Yes you need to implode:

echo implode(',', $check);

You don't need to put it inside an array:

$arr = array($check); // no need
