$new_arr[]=array("new_id"=> $arr[$key][$keys],"new_value"=>$newvalue);
在foreach内这个是我定义的数组，
我在循环外，
var_dump($new_arr); 后 所出现的结果是，
array(4) {
[0]=> array(2) { ["new_id"]=> string(1) "1" ["new_value"]=> float(0.5) }
[1]=> array(2) { ["new_id"]=> string(1) "2" ["new_value"]=> float(0.5) }
[2]=> array(2) { ["new_id"]=> string(1) "1" ["new_value"]=> int(1) }
[3]=> array(2) { ["new_id"]=> string(1) "1" ["new_value"]=> float(0.5) }
[4]=> array(2) { ["new_id"]=> string(1) "6" ["new_value"]=> float(0.5) }
}
我现在想实现的最终结果是这样的：
array(2) { ["new_id"]=> string(1) "1" ["new_value"]=> int(2) }
array(2) { ["new_id"]=> string(1) "2" ["new_value"]=> float(0.5)}
array(2) { ["new_id"]=> string(1) "6" ["new_value"]=> float(0.5)}
// 解释一下： 就是new_id 这一列 把所有 相同的值 合并到一起， 并且 对应的
new_value 这一列进行相加。
希望大家能帮我解答， 今天晚上我会一直在线等。 很急， 谢谢大家了。
foreach($new_arr as $k => $array){
if(isset($result[$array['new_id']]['new_value'])){
$result[$array['new_id']]['new_value'] += $array['new_value'];
}else{
$result[$array['new_id']]['new_value'] = $array['new_value'];
}
}
我测试过，没问题，如果还有什么不对的随时留言。
你觉得好的话,就拿去借鉴一下.
