假设有10个网站，分布在各地，它们的库存要同步，而数据库不支持远程连接。 我们要实时地取得服务器的库存数，可以通过很多种方法，我所知道的有以下几种： ·CURL方式 ·SOCKET方式 ·PHP5中的SOAP方式 以下分别给出示例来实现它： CURL方式 client.php
＜?php$psecode = ’NDE005’;$website = ’’;$amt = 1;$pwd = 123456;$ch = curl_init();$curl_url = "" . $website . "&pwd=" . $pwd . "&action=check&pseid=" . $psecode . "&amt=" . $amt;curl_setopt($ch, CURLOPT_URL, $curl_url);curl_setopt($ch, CURLOPT_POST, 1);curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//不直接输出，返回到变量$curl_result = curl_exec($ch);$result = explode(’,’, $curl_result);curl_close($ch);print_r($result);?＞ 服务器端只需按一定的格式输出，然后客户端按此格式接收就可以了如：
echo "OK," . $fpsecode . "," . $fbalance ;//以逗号分隔 SOCKET方式 这个要借助第三方类库HttpClient,可以到这里下载：http://scripts.incutio.com/httpclient/
