我想要获得一个声音文件打印在一个PHP页面上。我使用下面的代码。我想当我运行这个脚本时，它会显示一个可下载的声音文件，但它会打印一些文本。你认为我应该怎么做才能解决这个问题？file_get_contents打印文本不是声音
<?php
$mylanguage=$_GET["mylanguage"];
$soundtext=$_GET["soundtext"];
echo stream_get_contents("http://api.microsofttranslator.com/V2/http.svc/Speak?appId=9CF5D9435A249BB484EC6DB50FFFB94C6733DEFB&language=$mylanguage&format=audio/wav&text=$soundtext");
?>
发送正确的标题。默认情况下，PHP发送Content-Type: text/html。如果您发送其他内容，则必须自行发送标题。
这是什么样的声音文件？
这是一个wav文件。我应该如何添加音频标题？ – user1215741 2012-02-26 14:48:50
标题（ “内容类型：音频/ vnd.wave”） – ckruse 2012-02-27 05:30:22
我用头（ 'HTTP：// ...'）得到它的工作。 – user1215741 2012-02-28 19:58:10
从PHP.net：
stream_get_contents
（PHP 5）
stream_get_contents - 读取流的剩余部分转换为字符串
所以它只是返回一个字符串表示的文件内容。不是文件本身。
所以我能做些什么来接收文件本身？ – user1215741 2012-02-26 14:48:22
使用['file_get_contents']（http://php.net/file_get_contents）。 – hakre 2012-02-26 15:51:00
stream_get_contents不能这样工作。它需要现有的开放处理。
你需要的是这个，
$url = "http://api.microsofttranslator.com/V2/http.svc/Speak?appId=9CF5D9435A249BB484EC6DB50FFFB94C6733DEFB&language=$mylanguage&format=audio/wav&text=$soundtext";
$fh = fopen($url, "rb"); // this rb makes it binary safe
$audio_data = stream_get_contents($fh)
要将其回显到客户端，你需要适当Content-Type头。请检查/etc/mime.types以获取适当的内容类型。
假设它是一个波形音频。使用下面的代码。
header("Content-type: audio/x-wav");
echo $audio_data;
这是在MS API网站的例子：http://msdn.microsoft.com/en-us/library/ff512420.aspx#phpexample
在过去try块就可以看到头设置header('Content-Type: audio/mp3');

'stream_get_contents'不工作的方式。看到我的回答 – 2012-02-26 14:58:33
