File Headers

How can I get the mimetype of a file before I open it?

Hi,

How can I check the mime type of a file before I open it so I know it is the correct format?

This is for a file already on the server, not uploaded.

Thank you.

Since the Mimetype Functions [php.net] have been deprecated, you might want to use the Fileinfo Functions [php.net].
