php 判断数组中id相同时合并

将数组中相同id的数组合并，其他值相加或合并：列子

$data = [["name" => "唐鸿",
                "year" => 2025,
                "month" => 202504,
                "remark" => "22",
                "user_id" => 2394,
                "adjust_prices" => "22"
            ],
                ["name" => "郑秋燕",
                    "year" => 2025,
                    "month" => 202504,
                    "remark" => "测试1",
                    "user_id" => 5477,
                    "adjust_prices" => 10
                ],
                ["name" => "杨建华",
                    "year" => 2025,
                    "month" => 202504,
                    "remark" => "222",
                    "user_id" => 10921,
                    "adjust_prices" => 0
                ],
                ["name" => "唐鸿",
                    "year" => 2025,
                    "month" => 202504,
                    "remark" => "测试33",
                    "user_id" => 2394,
                    "adjust_prices" => "56"
                ],
                ["name" => "郑秋燕",
                    "year" => 2025,
                    "month" => 202504,
                    "remark" => "22",
                    "user_id" => 5477,
                    "adjust_prices" => 100
                ]];

使用方法 

$arr = [];
            foreach($data as $k=>$v){
                $key = $v['user_id'];
                $arr[$key]['user_id'] = $v['user_id'];
                $arr[$key]['name'] = $v['name'];
                $arr[$key]['year'] = $v['year'];
                $arr[$key]['month'] = $v['month'];
                if(!empty($arr[$key]['adjust_prices'])){
                    $arr[$key]['adjust_prices'] += $v['adjust_prices'];
                }else{
                    $arr[$key]['adjust_prices'] = $v['adjust_prices'];
                }
                if(!empty($arr[$key]['remark'])){
                    $arr[$key]['remark'] .= '，'.$v['remark'];
                }else{
                    $arr[$key]['remark'] = $v['remark'];
                }
            }
var_dump($arr);
