I am in the first step, the request _token, using the Curl method, the return value is always false, after verification, Tw Itter using the TLS mechanism, it seems to only support the certificate authorization, check the relevant documents also did not indicate the version of the determination, after a few attempts to return or FAL SE,, depressed dead,, exactly what is the problem ah,, have done, give a point of advice!

Reply to discussion (solution)

Why did no one reply, has been a Twitter third-party landing??

Really, no one's ever done Twitter?

Echo ' Curl error: '. Curl_error ($ch);

No, you print and see if Curl has any error messages.
