php如何让数组key相同的相加？

Question

打印出来的数组结构！

代码如下：

function GetStatisticsCOUNTS()
{
global $cqwebserviceBase;
$search_arr = $cqwebserviceBase ->GetStatisticsCOUNT();
$search_arr = json_decode($search_arr,true);
//var_dump($search_arr);die();
global $webserviceBase;
$count_arr =$webserviceBase->GetStatisticsCOUNT();
$count_arr = json_decode($count_arr,true);
//var_dump($count_arr);die();

$count_arr3['data']=array_merge($search_arr['data'],$count_arr['data']);
$item = array();
foreach($count_arr3 as $key=>$value){

    foreach($value as $k=>$v){
        if(isset($item[$k])){
            $item[$k] = $item[$k] +$v;
        }else{
            $item[$k] = $v;
        }
    }
}
arsort($item);
print_r($item);die();
//return $item;

}
