cURL to pass htaccess authentication? [RESOLVED]

[Phenix]

Do you know how to use CURL, Client URL Library Functions to get a page that is protected with htaccess if you know the username and password for the realm?

I tried this

$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_USERPWD, "[username]:[password]");
//curl_setopt ($ch, CURLOPT_HEADER, 0); with and without this line
curl_exec ($ch);
curl_close ($ch);

but it says I didn't authenticate.

I've used it in the past to get an unprotected url and even to pass info via post.

Or is there a way to pass it in the url like we would for ftp?

ftp(http)://username:[email protected]/thePath/theFile.php
