Part of the array within $_FILES superglobal gives the mime type for the
file. Is this 100% reliable / accurate? If the mime type says the file
type is jpeg is it always right?


It depends on your definition of "right"... If I understand correctly,
MIME type is determined based on the file's extension.

Thank you for the reply. So, what would happen if i took a file named photo.jpg and changed its name to:

1. photo.xyz

2. photo.gif

Different types of files will require different types of processing so it is very important that I can work out what the file type is.
