What on my PHP Curl call do I need to add to read a response's custom headers?

I tried a few several ways to read the responses custom header but have not been able to. I know the response I get is served by nginx and the custom header names start with X-......
$endpoint = 'url here';
$ch = curl_init( $endpoint );
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_HEADERFUNCTION, 'cbFunc');
$result = curl_exec($ch);
print_r( curl_getinfo($ch ) );

The PHP manual is an excellent reference guide an a good starting point when you run into problems like this.
CURLOPT_HEADERFUNCTION [Set value to] A callback accepting five parameters.
hence
log_headers('init');
$endpoint = 'url here';
$ch = curl_init( $endpoint );
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_HEADERFUNCTION, 'log_headers');
$result = curl_exec($ch);
$headers=log_headers();
print_r($headers);
function log_headers($ch=false, $headers=false)
static $hdrs;
if (is_array($hrs) && $ch===$headers===false)
return $hdrs;
elseif ($ch==='init')
$hdrs=array();
return 0;
$hdrs=$headers;
return strlen($headers);
