The gopher protocol, as defined by » RFC 1436,
is generally considered the ancestor of the modern HTTP protocol.
However, gopher was also intended to provide references to non-gopher
resources including telnet, wais, nntp, and even http. This extension
adds gopher support to PHP's URL Wrappers,
and provides a helper function gopher_parsedir() to
make sense of gopher formatted directory listings.
