Answer 1

You can use cURL to make http requests with PHP. The following code makes the request you described with the correct headers.

<?php
$crl = curl_init("https://httpbin.org/get?\$filter=ia_itemid+eq+5");

$header = array();
$header[] = 'Authorization: IC-TOKEN Credential=127896438762198746123';
$header[] = 'Accept: */*';

curl_setopt($crl, CURLOPT_HTTPHEADER,$header);
$rest = curl_exec($crl);

curl_close($crl);

print_r($rest);

?>

I'm using httpbin.org so you can check the headers and other parameters of your request.
