如何获取$photos>标签数据？

Question

在Graph API > Photo中，我使用以下脚本来获取Photo属性

    $response = file_get_contents($token_url);
    if($response=='')   {   echo "<script>window.location='index.php'</script>";    }

    $params = null;
    parse_str($response, $params);

    $fb_photo_id='10150361640936173';
    $graph_url_photos = "https://graph.facebook.com/" . $fb_photo_id . "?access_token=" 
    . $params['access_token'];
    $photos = json_decode(file_get_contents($graph_url_photos));
    }  


    ("token " . $params['access_token']);
    echo $photos_id=$photos->id; echo "</br>";

问:如何获取$photos->tags的数据？

Answer 1

下面是访问它的方式：

<?php

// ... your code here...
if(!empty($photos->tags)) {
    foreach($photos->tags->data as $tag)
        echo "ID: {$tag->id}<br />Name: {$tag->name}<br />X: {$tag->x}<br />Y: {$tag->y}<br />Created on: {$tag->created_time}<br /><br />";
}

您可以使用此页面测试Graph API调用：https://developers.facebook.com/tools/explorer

对于您的示例：https://developers.facebook.com/tools/explorer?method=GET&path=10150361640936173

你会看到“标签”结构是这样的：

"tags": {
    "data": [
      {
        "id": "1696691267",
        "name": "黃柏淇",
        "x": 64.375,
        "y": 80.2619,
        "created_time": "2011-11-07T09:12:22+0000"
      },
      {
        "id": "1705329218",
        "name": "Austin Ng",
        "x": 80.4543,
        "y": 48.0512,
        "created_time": "2011-11-07T09:12:22+0000"
      }
    ]
  },
