使用PHP将Twitter API解析为GEOJSON

Question

我尝试解析来自twitter api的响应，以便为GeoJSon创建输出。

但我无法检索值以创建我的$ features变量

$original_data = json_decode($response, true);
$features = array();
foreach($original_data as $tweet)
{
    $features[] = array(
        'type' => 'Feature',
        'properties' => array(
                'NAME' => $tweet->text
        ),
        'geometry' => array(
                "type"=> "Point",
                "coordinates"=> array(
                    "todo",
                    "todo"
                )
        )
    );
}
$new_data = array(
    'type' => 'FeatureCollection',
    'features' => $features
);

$ original_data输出：

array(2) {
  ["statuses"]=>
  array(15) {
    [0]=>
    array(25) {
      ["created_at"]=>
      string(30) "Mon Jul 25 09:59:38 +0000 2016"
      ["id"]=>
      int(757515646938804225)
      ["id_str"]=>
      string(18) "757515646938804225"
      ["text"]=>
      string(117) "#wp_Dev #ajax #stackoverflow How to handle big integer numbers in JSON response in Javascript"
      ["truncated"]=>
      bool(false)
      ["entities"]=>
      array(4) {
        ["hashtags"]=>

我的输出必须是这样的：

{
    "type": "FeatureCollection",
    "features": [
        {
            "type": "Feature",
            "properties": {
                "NAME": "name"
            },
            "geometry": {
                "type": "Point",
                "coordinates": [
                    "todo",
                    "todo"
                ]
            }
        },
