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

问题是我将"application/vnd.ms-office"作为我尝试上传的任何MSOFFICE文件的文件类型.我不希望只允许所有MSOFFICE文件.DOC.这有解决方法吗？

**请注意,这些MSOFFICE类型文件是在OPENOFFICE中创建的,这会有所不同吗？

Answer 1

在知道文件是Office文档(application/vnd.ms-office)并手动设置当前文件的正确MIME 之后,您可以做的最好的事情是验证文件扩展名.

如果您有权访问Apache,则可以添加正确的MIME conf/mime.types

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