讯飞语音接口用php接入，如何把response body的音频数据保存为文件

[zxh_33]

文档如下：
http://doc.xfyun.cn/rest_api/%E8%AF%AD%E9%9F%B3%E5%90%88%E6%88%90.html

本地代码如下，可以正常获得返回：

<?php
//用户参数
$apikey = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';
$appid = 'xxxxxxx';
$CurTime = (string)time();
$audioType = 'raw';
//语音参数
$json = array('aue' => $audioType, 'auf' => 'audio/L16;rate=16000', 'voice_name' => 'xiaoyan');
$param = base64_encode(utf8_encode(json_encode($json, JSON_UNESCAPED_SLASHES)));
$body = 'text=讯飞是中国最大的智能语音技术提供商';
//验证参数
$checkSum = md5($apikey . $CurTime . $param);
//http头
$header = array(
    'X-Appid:' . $appid,
    'X-CurTime:' . $CurTime,
    'X-Param:' . $param,
    'X-CheckSum:' . $checkSum,
);
//请求
$url = 'http://api.xfyun.cn/v1/service/v1/tts';
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 120);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_POSTFIELDS, $body);
$result = curl_exec($ch);
curl_close($ch);
//处理响应
echo($result);
$saveType = $audioType == 'raw' ? '.wav' : '.mp3';
$saveName = $CurTime . $saveType;
// TODO:save wav file

echo结果：


文档示例是python,response.content可以直接获取，PHP有没有类似方法呢。直接写$result放不出来，CURLOPT_HEADER,false也是。

刚刚发现，改成返回mp3格式就可以了 第6行，$audioType = 'lame'; 34行 TODO ： $save=fopen($saveName,'w'); fwrite($save,$result); fclose($save); 放出来了

所以为什么wav不行

[zxh_33]

mp3把返回头一起写进去也可以正常播放

但是wav格式写进返回头就放不出来。想要存wav格式就要类似python的response.content方法，php中如何实现？

您好，我看您也是做的这一块，想向您咨询个问题，那个我要做文本理解，运用PHP webapi ，运行以后出现这个结果，不能成功返回，想让您帮忙看看是什么原因？
这个是运行结果
