PHP与服务器端通讯方法

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。大家要实时地获得服务器的库存数，可以通过非常多种办法，我所知晓的有以下几种：＜?h3hh3require_once ’class/Htth3Client.h3hh3’;$h3arams = array;$h3ageContents = Htth3Client::quickPost;$result = exh3lode;h3rint_r;?＞

PHP5中的SOAP方法

server.php

＜?php function getQuote { global $dbh;$result = array;try {$query = "SELECT fprice, fcansale, fbalance,

 fbaltip FROM tblbalance where upper) 

= :psep limit 1";$stmt = $dbh-＞prepare;$stmt-＞execute)));$stmt-＞bindColumn;$stmt-＞bindColumn;$stmt-＞bindColumn;$stmt-＞bindColumn;while) {//}} catch  {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;} catch  {die); }ini_set; // disabling WSDL cache $server = new SoapServer; //配置文件$server-＞addFunction; $server-＞handle; ?＞

client.php

·CURL方法
·SOCKET方法
·PHP5中的SOAP方法

以下分别给出示例来达成它：

echo "OK," . $fh3seh3 . "," . $fbalance ;//以逗号分隔

SOCKET方法

这个要借用第三方类库HttpClient,可以到这里下载：http://scripts.incutio.com/httpclient/

CURL方法

client.php

＜?php$psep = ’NDE005’;$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=" . $psep . "&amt=" . $amt;curl_seTOPt;curl_seTOPt;curl_seTOPt;//不直接输出，返回到变量$curl_result = curl_exec;$result = explode;curl_close;print_r;?＞ 

服务器端仅需按肯定的格式输出，然后推广客户端按此格式接收就好了如：

＜?php$psep = ’NDE005’;$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=" . $psep . "&amt=" . $amt;curl_seTOPt;curl_seTOPt;curl_seTOPt;//不直接输出，返回到变量$curl_result = curl_exec;$result = explode;curl_close;print_r;?＞ 

服务器端仅需按肯定的格式输出，然后推广客户端按此格式接收就好了如：

echo "OK," . $fpsep . "," . $fbalance ;//以逗号分隔

SOCKET方法

这个要借用第三方类库HttpClient,可以到这里下载：http://scripts.incutio.com/httpclient/

＜?phprequire_once ’class/HttpClient.php’;$params = array;$pageContents = HttpClient::quickPost;$result = explode;print_r;?＞
