What does php's CURLOPT_USERPWD do
Is it modifying the url to this?:
username:password@someurl.com
No, the url still the same. You can check with
curl_getinfo($ch, CURLINFO_EFFECTIVE_URL);This
$encodedAuth = base64_encode(self::$pfAdapterUser.":".self::$pfAdapterPasswd);curl_setopt($ch, CURLOPT_HTTPHEADER, array("Authorization: Basic ".$encodedAuth));And this
curl_setopt($ch, CURLOPT_USERPWD, self::$pfAdapterUser.":".self::$pfAdapterPasswd);are doing the same thing so there's no need to use them together (although it won't break), use one and it will work fine.
