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 = 0;

$rest = new COM("Chilkat.Rest");
$bTls = 1;
$bAutoReconnect = 1;
$success = $rest->Connect('example.com',443,$bTls,$bAutoReconnect);
if ($success == 0) {
    print $rest->LastErrorText . "\n";
    exit;
}

$success = $rest->SendReqNoBody('GET','/api/items/123');
if ($success == 0) {
    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->NumResponseHeaders;

for ($i = 0; $i <= $numHeaders - 1; $i++) {
    $name = $rest->responseHdrName($i);
    if ($rest->LastMethodSuccess == 0) {
        print $rest->LastErrorText . "\n";
        exit;
    }

    $value = $rest->responseHdrValue($i);
    if ($rest->LastMethodSuccess == 0) {
        print $rest->LastErrorText . "\n";
        exit;
    }

    print $name . ': ' . $value . "\n";
