Why is foreach not working?

Not really...I was still trying to use result_array() previously.

Also, Why is it that my count is off? It should be two, but it is only giving me 1 even though as you can see I am echoing two indicies.

Code:

$test = "";
foreach ($test_var as $value)
{
  $test .= $value['id'];
}
echo $test[0]." ".$test[1];
echo sizeof($test);
