Get a REST Response Header Value by Index

See more REST Examples

Demonstrates Rest.ResponseHdrValue, which returns the value of the response header at a zero-based index. The same index used with ResponseHdrName gives the corresponding field name.

<?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;
}

//  Return the value of the response header at a zero-based index.  Use the same index with
//  ResponseHdrName to get the corresponding field name.
$numHeaders = $rest->NumResponseHeaders;

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

    print 'Header ' . $i . ' value: ' . $value . "\n";
}
