不正确的MIME类型从PHP [英] Incorrect mime-type from PHP

问题描述

当上传的Power Point 2000文档（.PPT）在微软的Power Point创造了它是一个返回的应用程序/ vnd.ms-办公室MIME类型。我希望应用程序/ vnd.ms - PowerPoint中回来的：

When uploading a Power Point 2000 document (.ppt) created in Microsoft Power Point it is a returning a mime type of application/vnd.ms-office. I would expect application/vnd.ms-powerpoint to come back from:

    <?php
    $finfo = new finfo(FILEINFO_MIME);
    $mime_type = $finfo->file($filepath);

    // strip off the mime encoding information
    $mime_type = substr($mime_type, 0, strpos($mime_type, ';'));

任何想法，为什么这也许是这样吗？

Any ideas why this maybe the case?

我运行以下内容：

• 的Ubuntu


• PHP 5.2


• 的Apache 2

推荐答案

finfo ins't 100％可靠的，尤其是当它涉及到Microsoft Office文档。我不认为这是一个容易解决您的解决方案。你可以尝试，如果返回应用程序/ vnd.ms办公室，然后还检查文件的扩展名是 .PPT ，如果是，设置MIME类型应用程序/ vnd.ms - PowerPoint演示。当然，延期是没有意义的，但那些使用微软，有一个很好的机会和扩展名的文件 .PPT 是PowerPoint，而不是别的。

finfo ins't 100% reliable, especially when it comes to Microsoft Office documents. I don't think there is an easy fix to your solution. You might try, if it returns application/vnd.ms-office, then additionally check if the extension of the file is .ppt, and if it is, set the mime type to application/vnd.ms-powerpoint. Of course an extension is meaningless, but those using Microsoft, there is a good chance a file with extension .ppt is a powerpoint and not anything else.
