Getting "bool(false)" from MailChimp API 3 POST request - php

Question

All,
I'm trying to do a simple "post" to Mailchimp using the 3.0 API; however I'm just getting a bool(false) response from the below code. I know the MAILCHIMP_API_KEY and LIST_ID variables are correct... Help?
All I want to do is add an email & first name to a specific list.
$auth = base64_encode( 'user:'.MAILCHIMP_API_KEY);
$data = array(
'apikey' => MAILCHIMP_API_KEY,
'email' => $email,
'status' => 'subscribed',
'merge_fields' => array(
'FNAME' => $name
)
);
$json_data = json_encode($data);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://'.$server.'api.mailchimp.com/3.0/lists/'.NEW_LIST_ID.'/members/');
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json', 'Authorization: Basic '.$auth));
curl_setopt($ch, CURLOPT_USERAGENT, 'PHP-MCAPI/2.0');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_0);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $json_data);
$result = curl_exec($ch);
var_dump($result);
die('<br /><br />Mailchimp executed');

Just missed the dot after $server in the URL, and also should be email_address rather than email. But below is a working example if anyone needs it:
$auth = base64_encode( 'user:'.MAILCHIMP_API_KEY);
$data = array(
'apikey' => MAILCHIMP_API_KEY,
'email_address' => $email,
'status' => 'subscribed',
'merge_fields' => array(
'FNAME' => $name
)
);
$json_data = json_encode($data);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://'.$server.'.api.mailchimp.com/3.0/lists/'.NEW_LIST_ID.'/members');
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json', 'Authorization: Basic '.$auth));
curl_setopt($ch, CURLOPT_USERAGENT, 'PHP-MCAPI/2.0');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_0);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $json_data);
$result = curl_exec($ch);
die('<br /><br />Mailchimp executed');
