Replacement for File::mime() in Laravel 4 (to get mime type from file extension)

Question

Laravel 3 had a File::mime() method which made it easy to get a file\'s mime type from its extension:

$extension = File::extension($path);
$         


        

Answer 1

After reading that:

• PHP mime_content_type() is deprecated
• Its replacement FileInfo is unreliable
• Symfony's getMimeType() uses FileInfo (see my other answer)

I decided instead to port Laravel 3's implementation of File::mime() into a helper library within my Laravel 4 application. The Laravel 3 implementation just reads the MIME types from a config lookup array, based on file extension.

Solution:

• Copied application/config/mimes.php from my L3 project to app/config/mimes.php in my L4 project
• Made a FileHelper library with the File::mime() function code from the Laravel 3 File class.
