示例代码:
$ssdb_handle = new SSDB(); //可省略connect方法使用$ssdb_handle = new SSDB('127.0.0.1', 8888); $ssdb_handle->connect('127.0.0.1', 8888);$ssdb_handle->set('ssdb_version', '1.8.0');$ssdb_handle->get('ssdb_version');
本扩展支持的所有命令如果返回为NULL,代表可能的错误为命令参数错误、连接中断、服务器返回失败、客户端发送失败等
为兼容官方php代码实现的客户端,提供类别名SimpleSSDB 如 $ssdb_handle = new SimpleSSDB('127.0.0.1', 8888);
本扩展还提供了一个附近查询
//添加坐标$ssdb_handle->geo_set('geo_test', 'a', 31.197452, 121.515095);$ssdb_handle->geo_set('geo_test', 'b', 31.196456, 121.515778);$ssdb_handle->geo_set('geo_test', 'c', 31.197159, 121.518015);$ssdb_handle->geo_set('geo_test', 'd', 31.196282, 121.51563);$ssdb_handle->geo_set('geo_test', 'e', 31.203159, 121.518082);//查询b附近点距离不大于4000米,最大返回数量不超过10个$result = $ssdb_handle->geo_neighbour('geo_test', 'b', 4000, 10);print_r($result);
