Question

我正在使用以下代码来解析来自Twitter帐户的最新推文：

    $host = "http://search.twitter.com";
    $filename = "/search.json";

    $opts = array('http' => array(
        'method'=>"GET",
        'header'=>"Accept-language: en\r\n"
    ));
    $context = stream_context_create($opts);

    $search = "mashable";
    $search = str_replace(" ", "%20", $search);
    $count = "10";

    $a = "$host$filename?q=$search&rpp=$count&include_entities=true";
    echo "$a\n";
    $json = file_get_contents($a, false, $context);

    $obj = json_decode($json, true);
    $id = $obj['results'][0]['id'];
    $tweet = $obj['results'][0]['text'];
    $user = $obj['results'][0]['from_user'];
    $to_user = $obj['results'][0]['to_user'];
    $media_url = $obj['results'][0]['media_url'];

    #echo $json;
    echo "<br /><br />";
    echo "searching for $search\n tweet count: $count\n";
    echo "<br /><br /><b>tweets</b><br />";
    echo "tweet_id: $id <br />";
    echo "user: $user <br />";
    echo "Tweet: $tweet<br />";
    echo "to_user: $to_user <br />";
    echo "media: $media_url";
    echo ""

?>

我想提取以下值： - 用户名（发件人） - 推文（文字） - 给用户（如果是回复） - 媒体附件（图片）

代码正在运行但由于某种原因我只收到最新的推文而不是数字（$ count）值。我也无法收到推文的media_url值。我的问题是：怎么样？

Answer 1

你必须循环结果才能获得所有结果，而不是其中之一，例如：

$host = "http://search.twitter.com";
$filename = "/search.json";

$opts = array('http' => array(
    'method'=>"GET",
    'header'=>"Accept-language: en\r\n"
));
$context = stream_context_create($opts);

$search = "mashable";
$search = str_replace(" ", "%20", $search);
$count = "10";

$a = "$host$filename?q=$search&rpp=$count&include_entities=true";
echo "$a\n";
$json = file_get_contents($a, false, $context);

$obj = json_decode($json, true);

foreach ($obj['results'] as $index => $result) {
    $id = $result['id'];
    $tweet = $result['text'];
    $user = $result['from_user'];
    $to_user = $result['to_user'];
    $media_url = $result['media_url'];

    #echo $json;
    echo "<br /><br />";
    echo "searching for $search\n tweet count: $count\n";
    echo "<br /><br /><b>tweets</b><br />";
    echo "tweet_id: $id <br />";
    echo "user: $user <br />";
    echo "Tweet: $tweet<br />";
    echo "to_user: $to_user <br />";
    echo "media: $media_url";
    echo "";
}

另外，当我做print_r($obj);时，我看不到任何media_url值 - 看起来不像Twitter那样，这就是你无法访问它的原因。< / p>

我找到了接收每条推文的media_url参数的解决方案：

$media_url = $result['entities']['media'][0]['media_url']

PHP以json格式获取最新推文
