(PHP ActiveX) HTTP HEAD Request

Sends an HTTP HEAD request and gets the response.

Note: The response to an HTTP HEAD request is always just the response header. The reponse body is always 0 length (thus the reason it's called a "HEAD" request..)

Note: This example requires Chilkat v11.0.0 or greater.

<?php

$success = 0;

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

$http = new COM("Chilkat.Http");

// If the URL uses "https://", then the connection will be TLS.
// Otherwise it will be TCP.

// A failure is when we don't get any response.  It could be a timeout, an inability to connect, etc.
// For example, a "404 Not Found" response is still a response, and thus deemed success in terms of the API..

$resp = new COM("Chilkat.HttpResponse");
$success = $http->HttpNoBody('HEAD','https://example-code.com/',$resp);
if ($success == 0) {
    print $http->LastErrorText . "\n";
    exit;
}

// Examine the response.
print 'Status Code = ' . $resp->StatusCode . "\n";
print 'Status Line = ' . $resp->StatusLine . "\n";

print '----' . "\n";

print 'Num Header Fields: ' . $numHeaderFields . "\n";

for ($i = 0; $i <= $numHeaderFields - 1; $i++) {
    print $resp->getHeaderName($i) . ': ' . $resp->getHeaderValue($i) . "\n";
