我有以下网址。
$url="https://graph.facebook.com/v2.8/page_id?fields=albums%7Bphotos.fields(source)%7D&access_token=access_token";
并获取此类数据。
$ch=curl_init();
CURL_SETOPT($ch,CURLOPT_URL,$url);
CURL_SETOPT($ch,CURLOPT_RETURNTRANSFER, 1);
$json=json_decode(curl_exec($ch),true);
当我打印数据时，它看起来如下所示。

现在我想从数组中获取 source 并将其放入图像标记。如下。
<img src="url_from the array for each picture"/>
我是这样想的，但没有得到消息来源。
foreach($json as $key){
echo $key['source'];
}
如何获取循环源并显示所有图像？
答案 0 :(得分：1)
将您的json_encode行更改为：$json=json_decode(curl_exec($ch));
然后访问您的信息：
foreach($json->albums->data as $album){
foreach($album->photos->data as $photo){
echo '<img src="'.$photo->source.'"/>';
}
}
答案 1 :(得分：0)
这是一个多维数组
它返回所有专辑和照片。
使用以下内容循环并显示所有图像..
// for each Album
foreach($json['albums']['data'] as $album)
{
// for each photos in current album
foreach($album['photos']['data'] as $photo )
{
echo '<img src="'. $photo['source'] .'"/>';
}
}
答案 2 :(得分：0)
您需要循环播放相册，然后循环播放这些相册中的照片，例如：
$albums = $json["albums"];
foreach ($albums["data"] as $album) {
foreach($album["photos"]["data"] as $photo) {
echo $photo["source"];
}
}
