It seems to me that curl is about automating tasks. A common task is
uploading a file along with that file's content type. Would it not be
easier for curl users if curl was able to automatically determine the
content type of files rather than requiring users to determine the
content type themselves and manually set it? There is already a function
in libcurl that returns the content type for a given file name. It is
logical to me that this function should be able to return the content
type for more than 5 hard-coded types. Being able to override this
determination is an excellent feature, but I feel the automatic type
detection could be more flexible. I think it is helpful to be able to
accomplish the same task in more than one way. However, I'm sure the
developers are all very busy working on higher priority features, which
is fine by me.

I agree that PHP's support for curl could be done better. Not the least
of which is better documentation for the many options, much like the way
curl documents the same options. I'm sure they will continue to improve
it. It is on my todo list to submit a feature request to support setting
the content type.
