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();

?>
