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 = ’www.abc.com’;
$amt = 1;
$pwd = 123456;
$ch = curl_init();
$curl_url = "http://ics1.server.com/index.php?web=" . $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/

＜?php
require_once ’class/HttpClient.php’;
$params = array(’web’ =＞ ’www.abc.com’,
’pwd’ =＞ ’123456’,
’action’ =＞ ’check’,
’pseid’ =＞ ’NDE005’,
’amt’ =＞ 1);
$pageContents = HttpClient::quickPost(’http://ics.server.com/index.php’, $params);
$result = explode(’,’, $pageContents);
print_r($result);

　　PHP5中的SOAP方式

　　server.php

＜?php 
function getQuote($fpsecode) { 
global $dbh;
$result = array();
try {
$query = "SELECT fprice, fcansale, fbalance, fbaltip FROM tblbalance where upper(trim(fpsecode)) = :psecode limit 1";
$stmt = $dbh-＞prepare($query);
$stmt-＞execute(array(’:psecode’ =＞ strtoupper(trim($fpsecode))));
$stmt-＞bindColumn(’fprice’, $fprice);
$stmt-＞bindColumn(’fcansale’, $fcansale);
$stmt-＞bindColumn(’fbalance’, $fbalance);
$stmt-＞bindColumn(’fbaltip’, $fbaltip);
while($row = $stmt-＞fetch(PDO_FETCH_BOUND)) {
//
}
} catch (PDOException $e) {
echo $e-＞getMessage();
}
return $fprice; //你可以返回一个数组
} 

$dsn = ’pgsql:host=192.168.*.* port=5432 dbname=db user=123456 password=123456’;
try {
$dbh = new PDO($dsn);
} catch (PDOException $e) {
die(’Connection failed: ’ . $e-＞getMessage()); 
}
ini_set("soap.wsdl_cache_enabled", "0"); // disabling WSDL cache 
$server = new SoapServer("stockquote.wsdl"); //配置文件
$server-＞addFunction("getQuote"); 
$server-＞handle(); 
?＞
