Once you've compiled PHP with cURL support, you can begin using
the cURL functions. The basic idea behind the cURL functions is
that you initialize a cURL session using the
curl_init(), then you can set all your
options for the transfer via the curl_setopt(),
then you can execute the session with the
curl_exec() and then you finish off
your session using the curl_close().
