Enumerate REST Response Header Names

See more REST Examples

Demonstrates Rest.ResponseHdrName, which returns the field name of the response header at a zero-based index. The example enumerates all headers, pairing each name with its value.

<?php

$success = false;

$rest = new CkRest();
$bTls = true;

}

$success = $rest->SendReqNoBody('GET','/api/items/123');
if ($success == false) {
    print $rest->lastErrorText() . "\n";
    exit;
}

$statusCode = $rest->ReadResponseHeader();
if ($statusCode < 0) {
    print $rest->lastErrorText() . "\n";
    exit;
}

//  Enumerate the response header fields by zero-based index.  ResponseHdrName returns the field name
//  and ResponseHdrValue returns the value at the same index.
$numHeaders = $rest->get_NumResponseHeaders();
