用Zend_Http來做Google翻譯

前幾天寫了一個小程式，利用Zend_Http來做Google翻譯：

require_once 'Zend/Http/Client.php';

$sentence = urlencode("Hello!  Welcome to visit my blog.");
$langpair = urlencode("en|zh-TW");

$url = "http://www.google.com/translate_t?langpair=$langpair&hl=en&ie=UTF8&text=$sentence";

$client = new Zend_Http_Client();
$client->setUri($url);
$client->setConfig(array(
    'maxredirects' => 0,
    'timeout'      => 30)
);
$client->setMethod(Zend_Http_Client::GET);
$client->setHeaders('User-Agent', 'Mozilla/4.0 (compatible; MSIE 5.5; Windows NT)');

$response = $client->request();

if ($response->isError())
{
 	echo "Error transmitting data.\n";
	echo "Server reply was: " . $response->getStatus() . " " . $response->getMessage() . "\n";
}else{
	$body = $response->getBody();
	$pattern = "/<div id=result_box dir=\"ltr\">(.*)<\/div><\/td>/Us";
	preg_match($pattern, $body, $matches);
	echo $matches[1];
}
