I'm looking for an array, preferably php or json, that maps file extensions to mime types. This is intended to be a fallback for servers without Fileinfo, mime_content_type, or PEAR support.

Here is my pathetic list atm...

// Fallback for servers without Fileinfo, mime_content_type, or PEAR support.

$mime_types_map = array(

If your using Apache .htaccess can be used to map mime types.

Never trust the mime type, this can be easily spoofed by the client. They could submit an exe and give it a mime type of text/plain if they wanted to.

All zip files begin with a standard local file header signature (0x04034b50) so you could check that the first 4 bytes of the file match the zip signature bytes. See the PKZIP Appnote for more details.

If you have the zip extension enabled, you can go even further and attempt to open and read the zip to make sure it is a fully valid zip file.

Something like this works well:

$zip = zip_open('/path/to/file.zip');
if (is_int($zip)) {
    echo "Error $zip encountered reading the file, is it a valid zip?";
} else {
    echo "Thanks for uploading a valid zip file!";
}

zip_open returns a resource if opened successfully, otherwise an integer representing the error that occurred reading the file.

EDIT: To elaborate on some of your questions:

About application/octet-stream: This is as you said, a very generic type. This just means any file that contains 8-bit data which is basically everything and anything. application/zip is the de-facto standard mime-type, but some clients will use other values as you have discovered. Also given the fact that a client can easily spoof any file type to use application/zip I wouldn't rely on $_FILES['fileatt']['type'] since it can be anything.

AFIK, mime_content_type() simply looks at the file extension and maps it to a mime type from a mime.types file on the system or built into PHP. If someone put a .zip extension on an exe file it would still register as application/zip. I beleive certain extensions may examine the file header.

Zip::open() returns TRUE if the file was opened successfully, or an integer error code. Therefore, == will give you a false positive on an error because any non-zero integer will evaluate to true using == since it will cast a non-zero integer to TRUE. If you are going to check the return from Zip::open you should always use $res === true in order to check for success. You can find the meanings of the error codes here in the comment at the bottom of the page.

Bottom Line: Since you said you are already extracting the zip, it may be less of a bother to validate based on the mime type, but instead it would be easier to just attempt to open the file and go based on the return value of open. If it returns true, you can figure the file is a valid zip (there could of course be errors later in the file, but they at least uploaded something resembling a zip file).

Hope that helps you out.

http://www.iana.org/assignments/media-types/ lists the "official" mime-types, but it doesn't prevent anyone making their own an not registering it with IANA.

You could try this:

// Instantiate the class
$s3 = new AmazonS3();

$bucket_name = 'my-bucket';
$file_name   = 'test1.txt';
$mime_type   = getMimeType($file_name);

$response = $s3->change_content_type($bucket_name, $file_name, $mime_type);

// Success?
var_dump($response->isOK());

function getMimeType($file) {
    // MIME types array
    $mimeTypes = array(

On Ubuntu, a directory mimetype is inode/directory

If you run, on Ubuntu:

$ mimetype /home/<your username>
/home/<your username>: inode/directory

There is a "text/directory" in the IANA standards (http://www.rfc-editor.org/rfc/rfc2425.txt and http://www.iana.org/assignments/media-types/text) but it was marked "deprecated".
