    copied!<p>Your method with <code>get_headers</code> and requesting the first response line will return the status code of the redirect (if any) <em>and</em> more importantly, it will do a GET request which will transfer the whole file.</p> <p>You need only a HEAD request and then to parse the headers and return the <em>last</em> status code. Following is a code example that does this, it's using <code>$http_response_header</code> instead of <code>get_headers</code>, but the format of the array is the same:</p> <pre><code>$url = 'http://example.com/'; $options['http'] = array( 'method' =&gt; "HEAD", 'ignore_errors' =&gt; 1, ); $context = stream_context_create($options); $body = file_get_contents($url, NULL, $context); $responses = parse_http_response_header($http_response_header); $code = $responses[0]['status']['code']; // last status code echo "Status code (after all redirects): $code&lt;br&gt;\n"; $number = count($responses); $redirects = $number - 1; echo "Number of responses: $number ($redirects Redirect(s))&lt;br&gt;\n"; if ($redirects) { $from = $url; foreach (array_reverse($responses) as $response) { if (!isset($response['fields']['LOCATION'])) break; $location = $response['fields']['LOCATION']; $code = $response['status']['code']; echo " * $from -- $code --&gt; $location&lt;br&gt;\n"; $from = $location; } echo "&lt;br&gt;\n"; } /** * parse_http_response_header * * @param array $headers as in $http_response_header * @return array status and headers grouped by response, last first */ function parse_http_response_header(array $headers) { $responses = array(); $buffer = NULL; foreach ($headers as $header) { if ('HTTP/' === substr($header, 0, 5)) { // add buffer on top of all responses if ($buffer) array_unshift($responses, $buffer); $buffer = array(); list($version, $code, $phrase) = explode(' ', $header, 3) + array('', FALSE, ''); $buffer['status'] = array( 'line' =&gt; $header, 'version' =&gt; $version, 'code' =&gt; (int) $code, 'phrase' =&gt; $phrase ); $fields = &amp;$buffer['fields']; $fields = array(); continue; } list($name, $value) = explode(': ', $header, 2) + array('', ''); // header-names are case insensitive $name = strtoupper($name); // values of multiple fields with the same name are normalized into // a comma separated list (HTTP/1.0+1.1) if (isset($fields[$name])) { $value = $fields[$name].','.$value; } $fields[$name] = $value; } unset($fields); // remove reference array_unshift($responses, $buffer); return $responses; } </code></pre> <p>For more information see: <a href="http://hakre.wordpress.com/2011/09/17/head-first-with-php-streams/" rel="nofollow noreferrer">HEAD first with PHP Streams</a>, at the end it contains example code how you can do the HEAD request with <code>get_headers</code> as well.</p> <p>Related: <a href="https://stackoverflow.com/questions/981954/how-can-one-check-to-see-if-a-remote-file-exists-using-php">How can one check to see if a remote file exists using PHP?</a></p>
