How to extract a specific index?

I'm learning how to upload in PHP and for security reason I'm checking
file mime when it is uploaded. Now how can I get access to the mime
part. I can get the details using a foreach loop but don't know how to
get the mime part.

Array ( [0] =280 [1] =184 [2] =2 [3] =width="280"
height="184" [bits] =8 [channels] =3 [mime] =image/jpeg )

Thanks.
