* 函数名：get_taobaoke_link ($num_iids)
* 函数用途：通过淘宝商品 num_iids 获取其对应的淘宝客手机版链接 
* 创建时间：2012-02-14
* 创建人：张宴 net@s135.com
* 参数说明：
*    $num_iids   淘宝商品ID（支持多个商品）数组，示例如下：
*          $num_iids[] = "13583512568";
*          $num_iids[] = "10809380078";
*          $num_iids[] = "10809380079";  
* 返回值：
*    下标为淘宝商品 num_iid ，值为淘宝客链接 click_url 的二维数组。如果无淘宝客链接，click_url 为空字符串，示例如下：
*          array(3) {
*            ["13583512568"]=>
*            string(191) "http://auction1.wap.taobao.com/auction/item_detail-0db2-13583512568.jhtml?tks=jUTwPLMDtUUNEZhqfEuTZqkZhGw1LA7%2BzCJBXCj27NpurHxjZN70Amg0DVaFU61pfnHwW%2FI4MZGm%0Awgb69kbb1NL8uwtu%2BDnyAunBCVDP"
