php - 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。我不想允许所有 MSOFFICE 文件，只允许 .DOC。有解决方法吗？

**请注意，这些 MSOFFICE 类型的文件是在 OPENOFFICE 中创建的，这会有什么不同吗？

Answer 1

最好的办法是在知道文件是 Office 文档后验证文件扩展名 (application/vnd.ms-office) 并为当前文件手动设置正确的 MIME。

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

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