数据类型:
{game_id:111,type:2,num:504},{game_id:111,type:6,num:8154},{game_id:111,type:41,num:3426},{game_id:111,type:42,num:45},{game_id:111,type:43,num:1873}
需求：
把type=41 42 42的num相加 type 1 10相加
结果：
{game_id:111,type:2,num:504},{game_id:111,type:6,num:8154},{game_id:111,type:41,num:5344}
code：

以上就介绍了 php 根据某数组key计算和，包括了方面的内容，希望对php教程有兴趣的朋友有所帮助。
