php 根据某数组key计算和

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：

$str = "{"retCode":"0","retMsg":"成功","data":[{"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},{"game_id":"119","type":1,"num":38},{"game_id":"119","type":2,"num":381},{"game_id":"119","type":6,"num":189},{"game_id":"119","type":10,"num":21},{"game_id":"120","type":2,"num":31},{"game_id":"120","type":6,"num":291},{"game_id":"120","type":41,"num":90},{"game_id":"120","type":43,"num":49},{"game_id":"127","type":1,"num":9},{"game_id":"127","type":2,"num":111},{"game_id":"127","type":6,"num":60},{"game_id":"129","type":1,"num":11},{"game_id":"129","type":2,"num":11},{"game_id":"129","type":6,"num":48},{"game_id":"129","type":10,"num":2},{"game_id":"130","type":6,"num":1},{"game_id":"137","type":2,"num":1},{"game_id":"139","type":2,"num":1387},{"game_id":"139","type":6,"num":3858},{"game_id":"139","type":10,"num":2358},{"game_id":"142","type":2,"num":32},{"game_id":"142","type":6,"num":948},{"game_id":"142","type":41,"num":330},{"game_id":"142","type":42,"num":3},{"game_id":"142","type":43,"num":47},{"game_id":"156","type":2,"num":11436},{"game_id":"156","type":6,"num":38135},{"game_id":"156","type":10,"num":22170},{"game_id":"165","type":6,"num":6},{"game_id":"165","type":41,"num":3},{"game_id":"165","type":43,"num":1},{"game_id":"50","type":2,"num":3},{"game_id":"8f093ab4ad19a509208a8104605c6e42","type":2,"num":281},{"game_id":"92","type":1,"num":26},{"game_id":"92","type":2,"num":186},{"game_id":"92","type":6,"num":153},{"game_id":"94","type":1,"num":538},{"game_id":"94","type":2,"num":3357},{"game_id":"94","type":6,"num":2847},{"game_id":"94","type":10,"num":74}]}";
