PHP 数组转换

Question

1数组合并请问下怎么实现呢？谢谢了！ array(3) { [0] => array(7) { ["game_name"] => string(18) "趣看每日一笑" ["game_icon"] => string(32) "game_icon_wx0913c2de2ce8376a.png" ["id"] => int(1) ["gift_name"] => string(15) "进阶大礼包" ["gift_details"] => string(23) "金币*5000 砖石*100" ["need_score"] => int(30) ["gift_type"] => int(2) } [1] => array(7) { ["game_name"] => string(18) "趣看每日一笑" ["game_icon"] => string(32) "game_icon_wx0913c2de2ce8376a.png" ["id"] => int(2) ["gift_name"] => string(15) "高阶大礼包" ["gift_details"] => string(25) "金币*50000 砖石*1000" ["need_score"] => int(120) ["gift_type"] => int(2) } [2] => array(7) { ["game_name"] => string(18) "趣看热点事件" ["game_icon"] => string(32) "game_icon_wx945daf05d01dad39.png" ["id"] => int(3) ["gift_name"] => string(12) "初级礼包" ["gift_details"] => string(8) "红包*1" ["need_score"] => int(50) ["gift_type"] => int(1) } } 修改为 ： array(3) { [0] => array(7) { ["game_name"] => string(18) "趣看每日一笑" ["game_icon"] => string(32) "game_icon_wx0913c2de2ce8376a.png" ['gift']=>array(2){ [0]=>array(5){ ["id"] => int(1) ["gift_name"] => string(15) "进阶大礼包" ["gift_details"] => string(23) "金币*5000 砖石*100" ["need_score"] => int(30) ["gift_type"] => int(2) } [1]=>array(5){ ["id"] => int(2) ["gift_name"] => string(15) "高阶大礼包" ["gift_details"] => string(25) "金币*50000 砖石*1000" ["need_score"] => int(120) ["gift_type"] => int(2) } } } [2] => array(7) { ["game_name"] => string(18) "趣看热点事件" ["game_icon"] => string(32) "game_icon_wx945daf05d01dad39.png" ['gift']=>array(2){ [0]=>array(){ ["id"] => int(3) ["gift_name"] => string(12) "初级礼包" ["gift_details"] => string(8) "红包*1" ["need_score"] => int(50) ["gift_type"] => int(1) } } } } 数组代码，我也懒得写了。给个JSON 数组吧！方便装换测试 [ { "game_name": "趣看每日一笑", "game_icon": "game_icon_wx0913c2de2ce8376a.png", "id": 1, "gift_name": "进阶大礼包", "gift_details": "金币*5000 砖石*100", "need_score": 30, "gift_type": 2 }, { "game_name": "趣看每日一笑", "game_icon": "game_icon_wx0913c2de2ce8376a.png", "id": 2, "gift_name": "高阶大礼包", "gift_details": "金币*50000 砖石*1000", "need_score": 120, "gift_type": 2 }, { "game_name": "趣看热点事件", "game_icon": "game_icon_wx945daf05d01dad39.png", "id": 3, "gift_name": "初级礼包", "gift_details": "红包*1", "need_score": 50, "gift_type": 1 } ]
