How to do another request from last_assetid

[EnelGy]

For the first request I make usual request

$steam = "http://steamcommunity.com/inventory/" . $steamid . "/440/2?l=english?count=1000";
$json = file_get_contents($steam);
$data = json_decode($json, true);

Then I get more_items = 1; last_assetid=123 and I want to do another request which starts with the last_assetid. I know that next $steam should have ?start_assetid=123, but don't have any idea how Would I do it to keep the old content.

Please suggest me

You would want to use a loop to request inventories until Steam no longer reports that more items are available, and use array_merge to combine the result pages.
