可能重复：
curl_exec printing results when I don't want too

我遇到的问题是＆＃34; curl_exec＆＃34;将文本打印到屏幕上。这是我的代码：

$ch = curl_init("https://go.urbanairship.com/api/push/");
if ($ch) {
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_USERPWD, "***:***"); // omitted
    curl_setopt($ch, CURLOPT_HTTPHEADER, array ("Content-Type: application/json"));
    curl_setopt($ch, CURLOPT_POSTFIELDS, '{"device_tokens": ["' . $device_token . '"], "aps": {"alert": "Hello! fucker!"}}'); 
    curl_exec($ch);
}

在print_r(curl_getinfo($ch));给出后调用curl_exec($ch);。

Array ( [url] => https://go.urbanairship.com/api/push/ 
        [content_type] => application/json; charset=utf-8 
        [http_code] => 200 
        [header_size] => 222 
        [request_size] => 327 
        [filetime] => -1 
        [ssl_verify_result] => 0 
        [redirect_count] => 0 
        [total_time] => 0.111714 
        [namelookup_time] => 0.029124 
        [connect_time] => 0.036017 
        [pretransfer_time] => 0.065684 
        [size_upload] => 0 [size_download] => 4 
        [speed_download] => 35 
        [speed_upload] => 0 
        [download_content_length] => 4 
        [upload_content_length] => 0 
        [starttransfer_time] => 0.111686 
        [redirect_time] => 0 
      )

请求成功。我发现它打印为null很奇怪。有什么帮助吗？

添加

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

为什么“curl_exec”打印“null”？
