PHP api call header variable retrieval

Question

I'm working with an api that returns a number of useful variables within the header response, for example with...

Pragma → no-cache
Server → Apache
X-Pages → 1424

... I'd like to use the X-Pages variable to form some further logic. How do I retrieve this variable and use it within my php script?

My api currently call looks like this:

$username = "XXXXXXXX";
$password = "XXXXXXXX";
$remote_url = 'XXXXXXXX';

$headers = array();
$headers[] = "Authorization: Basic " . base64_encode("$username:$password");

$opts = array(
  'http'=>array(
    'method'=>"GET",
'header' => $headers

  )
);

$context = stream_context_create($opts);

$file1 = file_get_contents($remote_url, false, $context);

Thanks,

Matt

I'm calling it through PHP with a basic authorisation request, I can retrieve the body of the call and use that in my code, I just don't know how to access the header that is also being returned (I can see it's there using an api query app) ? — user1419810

Apologies, I'm pretty new to working with apis, I'm currently calling the api through the following: $username = "XXXXXXXX"; $password = "XXXXXXXX"; $remote_url = 'XXXXXXXX'; $headers = array(); $headers[] = "Authorization: Basic " . base64_encode("$username:$password"); $opts = array( 'http'=>array( 'method'=>"GET", 'header' => $headers ) ); $context = stream_context_create($opts); $file1 = file_get_contents($remote_url, false, $context); — user1419810

You can find the response headers in $http_response_header after making the call to file_get_contents - it'll be automatically populated in the local scope.
