XAMPP PHP MIME type wrong for .zip

Question

I'm using XAMPP 1.7.7 on Windows XP and doing a upload of a .zip file.

$_FILES shows:
array(1) {
["P24_File"]=>
array(5) {
["name"]=>
string(12) "File.zip"
["type"]=>
string(15) "unknown/unknown"
["tmp_name"]=>
string(22) "...\php1B.tmp"
["error"]=>
int(0)
["size"]=>
int(12927)
}
}

Surprisingly finfo_file() shows "application/zip; charset=binary"...

What's wrong with $_FILES?

Answer 1

This information is supplied by the browser , it has nothing to do with the server. Probably the client's computer doesn't have a ZIP utility installed, or the browser is not aware of the ZIP file type for some other reason.

Because it can be faked (or incorrect, as in your example), you can't trust that info anyway.

finfo_file() is the source to trust here.
