$ Curl = curl_init (); // Start a CURL session

Curl_setopt ($ curl, CURLOPT_URL, $ url); // address to be accessed

Curl_setopt ($ curl, CURLOPT_SSL_VERIFYPEER, 0); // Check the certificate source

Curl_setopt ($ curl, CURLOPT_SSL_VERIFYHOST, 1); // check whether the SSL encryption algorithm exists from the certificate

Curl_setopt ($ curl, CURLOPT_HTTPGET, 1); // send a regular GET request

Curl_setopt ($ curl, CURLOPT_COOKIEJAR, $ cookieFile); // Save the returned cookie information to the file

$ Res = curl_exec ($ curl );

Curl_close ($ curl );

Return $ res;

}

// 1.

$ Auth_url = "http://www.biuman.com/auth ";

GetCookie ($ auth_url); // Get the verification code cookie

// 2.

$ Url = 'http: // www.biuman.com/home'; // url submitted after login

$ Res = login ($ url );

Print_r ($ res );
