(PHP Extension) HTTP HEAD RequestSends 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..)
<?php // The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number. // For example, if using Chilkat v9.5.0.48, then include as shown here: include("chilkat_9_5_0.php"); // This example assumes the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. $http = new CkHttp(); // If the URL uses "https://", then the connection will be TLS. // Otherwise it will be TCP. // resp is a CkHttpResponse $resp = $http->GetHead('https://example-code.com/'); if ($http->get_LastMethodSuccess() != true) { // 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.. print $http->lastErrorText() . "\n"; exit; } // Examine the response. print 'Status Code = ' . $resp->get_StatusCode() . "\n"; print 'Status Line = ' . $resp->statusLine() . "\n"; print 'Status Text = ' . $resp->statusText() .
