static string getHttpAcceptHeader(array $extraTypes = array())

Generates an HTTP Accept header string

The string will contain all of the MIME Types that we are able to parse.

It is also possible to specify additional MIME types in the form array('text/plain' => 0.5) where 0.5 is the q value for that type. The types are sorted by q value before constructing the string.

Parameters

array $extraTypes extra MIME types to add
