在php中为exe文件获取不同的mime类型

Question

I am trying to get mime type of an exe file in PHP. It's returning application/x-dosexec . but the mime type of an exe file should be application/x-msdownload .

I am checking with a temporary file name($file_tmp_name) , using the code below:

$finfo = finfo_open(FILEINFO_MIME_TYPE);
echo finfo_file($finfo, $file_tmp_name);
finfo_close($finfo);

Answer 1

application/x-dosexec is actually a subtype of application/x-msdownload , specifically having the .exe glob.

You don't need to check for all possible mime types, just check if it belongs to the parent executable mime type. See how it's done with mediatype here .
