flex4.5+php5.2+amfphp通过RemoteObject交互

雪山飞鹄 — Fri, 28 Oct 2011 03:52:00 GMT

偶尔写写php感觉心情�q�是蛮舒畅的�Q�Java里的Struts+Hibernate+Spring写久了）�Q�写写php才知道，�q�种被解攄��感觉真好。不得不��_��php是一�U�服务器端比较精辟的语言�Q�难怪崇拜者这么多。就来整整flex��Z��php的交互，看好了，�q�里要介�l�的不是通过flex里面的HttpService�l��g与php交互�Q�而是借助AMFPHP通过RemoteObject方式来交互�?br />关于amfphp环境的搭建，请参考本人写的amfphp环境搭徏教程�Q�当焉��面写的比较粗略，有不清粗的可以联�p�L��?br />先来看看php端代�?br />ProductServices.php

php
class ProductServices{
    /**
    *query product list
    */
    function getProductList(){
        $link=@mysql_connect("localhost", "root", "") or die("Could not connect");
        mysql_select_db("compass",$link);
        mysql_query("set names utf8",$link);
        $result = mysql_query("SELECT * FROM product",$link);
        $array=array();
        while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
            array_push($array,$row);
        }
        mysql_free_result($result);
        mysql_close($link);
        return $array;
    }

    function findProductById($id){
        $link=@mysql_connect("localhost", "root", "") or die("Could not connect");
        mysql_select_db("compass",$link);
        mysql_query("set names utf8",$link);
        $result = mysql_query("SELECT * FROM product where id= ".$id,$link);
        $array=array();
        while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
            array_push($array,$row);
        }
        mysql_free_result($result);
        mysql_close($link);
        return $array;
    }

}
?>

在ProductServices.php文�g中，定义了一个类ProductServices�Q�里面封装了两个�Ҏ(gu��)��Q�getProductList�Q�）�Q�findProductById�Q?id�Q�里面内容很��单，一个是全部查询商品�Q�一个是�Ҏ(gu��)��Id查询商品

注意该文件存攄��位置C:\inetpub\wwwroot\amfphp\services\ �q�样可以被amfphp的资源管理器��索到
