在对 Gnip 进行了几次研究之后，我将它集成到了我的应用程序中，并且我设法添加了新规则并从 Gnip 获取流结果，但是现在我在将其转换为 PHP 数组并显示它时遇到了问题
我使用 CURLOPT_RETURNTRANSFER => TRUE 来不打印 curl 结果，并将其存储到变量中并使用 json_decode 函数对其进行解码，然后打印它但仍然得到一个空页面。
如果有人可以帮助我，这对我来说将节省大量时间
提前致谢
这是我的代码
$ch = curl_init();
curl_setopt_array($ch, array(
CURLOPT_URL => $stream_url,
CURLOPT_ENCODING => "gzip",
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_HTTPAUTH => CURLAUTH_BASIC,
CURLOPT_USERPWD => $user.":".$pass,
CURLOPT_WRITEFUNCTION => "print_out_data",
CURLOPT_RETURNTRANSFER => TRUE,
CURLOPT_LOW_SPEED_TIME=> 60,
CURLOPT_TIMEOUT => 10,
//CURLOPT_VERBOSE => true // uncomment for curl verbosity
));
$content = curl_exec($ch);
$arr = json_decode($content, true);
$foo = $arr['id'];
$bar = $arr['objectType'];
print_r($foo);
print_r($bar);
打印时得到的结果
