用Zend_Http做一個IP地理位址查詢

剛剛玩了一下「IP地址查询-IP地理位置查询系统-中文e讯」想說乾脆也用Zend_Http來做一個應用~

require_once 'Zend/Http/Client.php';

$ip = '163.17.131.33';

$url = "http://ip.cemsg.com/index.php";

$client = new Zend_Http_Client();
$client->setUri($url);
$client->setConfig(array(
    'maxredirects' => 0,
    'timeout'      => 30)
);
$client->setMethod(Zend_Http_Client::POST);
$client->setParameterPost('s', $ip);
$client->setParameterPost('doit', 1);
$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();
	$pattern = "/<div id=\"ip_pos\" style=\"color:#FF0000\">(.*)<\/div>/Us";
	preg_match($pattern, $body, $matches);
	echo $matches[1];
}

不過出來的結果好像似乎有點不準，上述的IP是學校的Web Server，但回傳給我的字串為何顯示「澳大利亚米尔顿」呵~ 不過有些還蠻準確的~
