想用foreach来获取gid, 得到以下的数据:gid 相同,
有什么办法排除同样的gid,一样的gid,只留一组.
<code>[ { "id": "151", "uid": "101497", "gid": "399", "create_time": "1462445116", "msg": null, "number": "148", "order_id": "2016050518451705537", "type": "0", "prepay_id": null, "code": null, "recharge": "0", "wid": "0", "end_time": "1462445416", "status": "1" }, { "id": "132", "uid": "101497", "gid": "399", "create_time": "1462420981", "msg": null, "number": "97", "order_id": "2016050512030120339", "type": "0", "prepay_id": null, "code": null, "recharge": "0", "wid": "0", "end_time": "1462421281", "status": "1" }, { "id": "133", "uid": "101497", "gid": "399", "create_time": "1462426436", "msg": null, "number": "97", "order_id": "2016050513335645342", "type": "0", "prepay_id": null, "code": null, "recharge": "0", "wid": "0", "end_time": "1462426736", "status": "1" } ]</code>

自己寫個函數去除重複的數據在遍歷啊
