Getting PageId (in PHP)

Calling https://en.wikipedia.org/w/api.php?action=query&titles=Main%20Page will return the page id:

{
        "batchcomplete": "",
        "query": {
                "pages": {
                        "15580374": {
                                "pageid": 15580374,
                                "ns": 0,
                                "title": "Main Page"
                        }
                }
        }
}

To extract get the first object property:

$page = current((Array)$data->query->pages);

Then you have access to the page id

$pageid = @$page->pageid;
