$arr=[['name'=>'三分公司','children'=>[['sum'=>156],['sum'=>12]]]];functiongetChildrenSum($children){$sum=0;if(is_array($children)){foreach($childrenas$item){$sum+=$item['sum'];if(isset($item['children'])){$sum+=getChildrenSum($item['children']);}}}return$sum;}$sum=array_reduce(array_filter($arr,function($item){return$item['name']==='三分公司';}),function($sum,$item){return$sum+getChildrenSum($item['children']);},0);echo$sum;
