MSOFFICE MIME类型验证

Question

我有以下内容：

$mimeTypes = array('application/msword'); //used to be an array

$finfo = new finfo(FILEINFO_MIME, "/usr/share/misc/magic"); 


$type = $finfo->file($_FILES['userfile']['tmp_name']);
$mime = substr($type, 0, strpos($type, ';'));


    if (in_array($mime, $mimeTypes)) 
      { //let it in

问题是，无论我尝试上传哪个MSOFFICE文件，都会得到"application/vnd.ms-office"类型的文件。我不希望允许所有的MSOFFICE文件，只想上传.DOC文件。是否有解决方法呢？

请注意这些MSOFFICE类型的文件是在OPENOFFICE中创建的，这会有什么影响吗？

Answer 1

在确认文件是Office文档(application/vnd.ms-office)后，最好的做法是验证文件扩展名，并手动设置当前文件的正确MIME类型。

如果您可以访问Apache，可以在conf/mime.types中添加正确的MIME类型。

application/msword doc
application/vnd.ms-excel xls
[..] etc
