What does php's CURLOPT_USERPWD do

问题

I was wondering what CURLOPT_USERPWD is actually doing to the url, header or data of a request. Is it INSTEAD OF the Authorization: Basic <base64 of user:pass> or does it work along side this?

Is it modifying the url to this?:

username:password@someurl.com

I saw some code like this so I am wondering, as it seems if I request that url in a NodeJS equivalent request it is not working with just an Authorization header (I have a theory the server is broken and ignoring the Auth header and using the username:password in the url):

    curl_setopt($ch, CURLOPT_URL, $url); 

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 

    $encodedAuth = base64_encode(self::$pfAdapterUser.":".self::$pfAdapterPasswd);

    curl_setopt($ch, CURLOPT_HTTPHEADER, array("Authentication : Basic ".$encodedAuth));
    curl_setopt($ch, CURLOPT_USERPWD, self::$pfAdapterUser.":".self::$pfAdapterPasswd);
    curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLINFO_HEADER_OUT, true);

Thanks

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.
