MvcCore extension to get:

Mimetype(s) strings array from file extension string
Extension(s) strings array from file mimetype string

This extension doesn't use PHP mime_content_type() function.
To recognize which mimetype has uploaded file by magic bytes does form control (input:file) validator itself using PHP fionfo extension.
This extension has only list of mimetypes and extensions to properly decide, which file extension could be finally stored on server HDD after magic bytes recognition.

IANA (http://www.iana.org/assignments/media-types/media-types.xhtml)
APACHE (http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types)
NGINX (http://hg.nginx.org/nginx/raw-file/default/conf/mime.types)
custom definitions in ./custom-mimes.json

Usage

use \MvcCore\Ext\Tools;

$mimeTypes = Tools\MimeTypesExtensions::GetMimeTypesByExtension('dmg');
// ['application/x-apple-diskimage', 'application/octet-stream']
var_dump($mimeTypes);

$mimeTypes = Tools\MimeTypesExtensions::GetMimeTypesByExtension('madness');
// NULL - means no data for given extension
var_dump($mimeTypes);

$extensions = Tools\MimeTypesExtensions::GetExtensionsByMimeType('application/msword');
// ['doc','dot'] - means mimetype `application/msword` could have two different extensions
var_dump($extensions);

$extensions = Tools\MimeTypesExtensions::GetExtensionsByMimeType('video/bmpeg');
// [''] - means file type is defined as file always without any extension
var_dump($extensions);
