I'll implement those feature in the master version of curl.

Looked at PHP sources to find how the similar CURLOPT_HEADERFUNCTION has been
implemented and here's my understanding:
- ext/curl/interface.c is the only file that needs modification
- Seems CURLOPT_SOCKOPTDATA, CURLOPT_OPENSOCKETDATA, CURLOPT_CLOSESOCKETDATA
cannot be exported to the end user, as PHP will need it internally to pass a
context to the callback function. No a big deal IMHO.
- remaining three options - CURLOPT_SOCKOPTFUNCTION,
CURLOPT_OPENSOCKETFUNCTION,
CURLOPT_CLOSESOCKETFUNCTION shall be added in PHP_MINIT_FUNCTION,
_php_curl_set_default_options and _php_curl_setopt.
- all the three callbacks shall be implemented using curl_write_header as a
model.
Hope this helps.

what do you think? maybe expose some new constants?

Description:
------------
libcurl has 6 callback options that are missing in PHP bindings, but give the
user
great control over the underlying socket:
- CURLOPT_SOCKOPTFUNCTION
- CURLOPT_SOCKOPTDATA
- CURLOPT_OPENSOCKETFUNCTION
- CURLOPT_OPENSOCKETDATA
- CURLOPT_CLOSESOCKETFUNCTION
- CURLOPT_CLOSESOCKETDATA
Without support for these options, developers can't set socket bindings,
options
and marks on connections done via cURL.
That is a great limitation for serious network applications written in PHP.
Here's
one real example:

under-php
