我正在尝试获取用户提要的所有图像。我正在创建的文件是一个 CRON 作业，但会检查数据库中是否有任何已提交的用户名，然后转到 Twitter API 并获取用户的提要，然后特别是图像。我遇到的问题是我似乎无法浏览响应。目前我正在使用 json_decode(TWITTERS RESPONSE HERE) 在此之后我无法进入“较低级别”的数据。我的代码如下：
//Loop through each user with twitter and lets get their feed
while( $user = mysqli_fetch_assoc($user_twitter_query) ){
//Lets get our twitter API call ready
$twitter_url = 'https://api.twitter.com/1.1/statuses/home_timeline.json';
$twitter_getfields = '?screen_name='.$user[twitter].'&count=20&include_rts=0&filter:images';
$twitter_requestMethod = 'GET';
$twitter = new TwitterAPIExchange($twitter_settings);
$response = $twitter->setGetfield($twitter_getfields)
->buildOauth($twitter_url, $twitter_requestMethod)
->performRequest();
//echo $response;
$data = json_decode($response);
if(!empty($data)){
$twitter_posts = $data->entities;
if(!empty($twitter_posts)){
foreach($twitter_posts->media AS $media_element){
$media = $media_element->media_url;
if(!empty($media)){
foreach ($media as $img) {
echo $img;
}
}
}
}
}
}
在 $data 上执行“var dump”时（我将 api 调用更改为“count=1”以节省它包含的空间：
array(1) { [0]=> object(stdClass)#5 (23) { ["created_at"]=> string(30) "Thu Sep 04 19:14:03 +0000 2014" ["id"]=> int(507607543678767104) ["id_str"]=> string(18) "507607543678767104" ["text"]=> string(70) "A look back at @Joan_Rivers' extraordinary life http://t.co/0C4a1cPJVh" ["source"]=> string(56) "Buffer" ["truncated"]=> bool(false) ["in_reply_to_status_id"]=> NULL ["in_reply_to_status_id_str"]=> NULL ["in_reply_to_user_id"]=> NULL ["in_reply_to_user_id_str"]=> NULL ["in_reply_to_screen_name"]=> NULL ["user"]=> object(stdClass)#6 (40) { ["id"]=> int(26371180) ["id_str"]=> string(8) "26371180" ["name"]=> string(9) "About.com" ["screen_name"]=> string(11) "aboutdotcom" ["location"]=> string(13) "New York City" ["description"]=> string(160) "More than 900 sites on everything from parenting and healthcare to technology, cooking & travel.
