My question may sound confusing to some people. But in fact it's a quite simple one. Let me clear you the scenario. I've an array titled $test_result_data as follows:

Use array_filter:

$filtered = array_filter($yourArray, function($element) use($test_pack_id) {
  return $element['test_pack_id'] == $test_pack_id;
});
