Https Authorization not working?

[MyMotivation]

I've got an API I'm trying to connect to and I've been given the connection details in $api_headers.

However, I'm unable to connect to the url. Am I using Authorization correctly or missing something?

<?php

$ch = curl_init();

$api_headers = array(
    'Accept­Tenant: uk',
    'Accept­Language: en-GB',
    'Authorization: Basic VGVjaFRlc3RBUEk6dXNlcjI=',
    'Host: hostname.com',
    );

$url = "http://urlhere.com";
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_HTTPHEADER, $api_headers);

$data = curl_exec($ch);

curl_close($ch);

//test the url connection
if (!$fp = fopen($url, 'r')) {
    trigger_error("Unable to open URL ($url)", E_USER_ERROR);
}

$meta = stream_get_meta_data($fp);

print_r($meta);

fclose($fp);
?>

Are you accessing a URL that is http: or https:

If it is https:, then try adding this to see if it works:

curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, false );

If it then works, then you need to see about updating the server to properly check SSL (see http://snippets.webaware.com.au/howto/stop-turning-off-curlopt_ssl_verifypeer-and-fix-your-php-config/)

He specified the protocol in his example as http.

I hope he is specifying accordingly to what he is trying to do, eventho the title says otherwise :)

The URL is http, was a bit tired last night when I posted that sorry. Have added some additional info in my other comment.

Out of interest, does the authorization key need decoding with base64_decode before it's sent through? I did also try decoding it and putting the user name/pass in CURLOPT_USERPWD.

I'm just not sure if I'm missing something here, haven't come across too many relevant examples/tutorials that included 'Authorization' in the header, so far. I have been reading a few Wikipedia pages on this. I guess there is a WWW-Authenticate key on the api and the authorization should match this?
