PHP calculates the sum based on an array key

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}]}';

$aaa =  json_decode($str, true);
$data = $aaa['data'];
$new_array = array();
$array1 = array(41,42,43);
$array2 = array(1,10);
foreach($data as $v){
	if(in_array($v['type'], $array2)){
		if(isset($new_array[$v['game_id']][$array2[0]]['num'])){
			$new_array[$v['game_id']][$array2[0]]['num'] += $v['num'];
		}  else {

		}
	}elseif (in_array($v['type'], $array1)) {
		if(isset($new_array[$v['game_id']][$array1[0]]['num'])){

		}
	}else{

}
foreach($new_array as $k1 => $v1) {

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。
