CURLOPT_SSLVERSION, 4

[msrougi]

Hi. I'm a
brazilian paygate owner and I communicate to my local Card Operator via XML (curl).
After they change their protocol to use SSL/TLS i couldn't use
curl_setopt($sessao_curl, CURLOPT_SSLVERSION, 3); any more. But if I
change it to 4 it goes Ok. Can you explain me why? And what the 4 really
does in the line?



Thanks a lot.
