简单实现了淘宝API的调用的类，暂时没有考虑session，可以参照淘宝api实现各种功能，比如获取宝贝详情、图片链接等。欢迎提建议
<php

class TaobaoApi {
    /*
     * 定义并初始化参数数组，某些固定参数可写在这个位置
     */

    protected $_param = array('app_key' => '21572060', 'v' => '2.0',
        'sign_method' => 'md5', 'format' => 'xml');
    /*
     * Sign值存储变量
     */
    protected $_sign;
    /*
     * 应用密码存储变量
     */
    public $secret = 'your secret';
    /*
     * 请求URL存储变量
     */
    protected $_url;

    public function run() {
        $this->createSign();
        $this->createRequestUrl();
        return $this->requestData();
    }

    /*
     * 通过魔法赋值向参数数组写入数据
     * @param string $name 数组名
     * @param string $value 数组键值
     */

    public function __set($name, $value) {
        $this->_param[$name] = $value;
    }

    /*
     * 组建Sign
     * @global $this->_param 参数数组
     * @global $this->secret 应用密钥
     */

    protected function createSign() {
        $this->_param['timestamp'] = date('Y-m-d H:i:s');
        ksort($this->_param, SORT_STRING); //数组按键值排序
        $tmp = '';
        foreach ($this->_param as $key => $value) {

        }
        $this->_sign = strtoupper(md5($this->secret . $tmp . $this->secret));
    }

    /*
     * 由参数和Sign值组合成请求URL
     * @global $this->_param
     * @global $this->url
