Question

我具有这样的多维数组，我想对所有“ quota”列的值求和，它们具有相同的id，相同的ip和相同的访问的ip

$array = array(
    "0" => array(
        "id" => 1,
        "ip" => 10.40.47.5,
        "visited_ip" => 10.40.40.10,
        "quota" => 20,
    ),
    "1" => array(
        "id" => 2,
        "ip" => 10.40.47.20,
        "visited_ip" => 10.40.40.10,
        "quota" => 10,
    ),
    "2" => array(
        "id" => 1,
        "ip" => 10.40.47.5,
        "visited_ip" => 10.40.40.10,
        "quota" => 30,
    )
);

我想要这样的结果

$array = array(
        "0" => array(
            "id" => 1,
            "ip" => 10.40.47.5,
            "visited_ip" => 10.40.40.10,
            "quota" => 50,
        ), 
        "1" => array(
            "id" => 2,
            "ip" => 10.40.47.20,
            "visited_ip" => 10.40.40.10,
            "quota" => 10,
        ),
    );

我需要您的帮助

环绕数组，并在关联数组中构建id和ip的复合。
循环后，使用array_values重置键。

编辑没有看到您也想访问ip。将其添加到复合关联数组键中。

foreach($array as $item){
    if(!isset($res[$item['id'] . ' ' . $item['ip']] . " " . "visited_ip")){
        $res[$item['id'] . ' ' . $item['ip'] . " " . "visited_ip"] = $item;
    }else{
        $res[$item['id'] . ' ' . $item['ip'] . " " . "visited_ip"]['quota'] += $item['quota'];
    }
}
$res = array_values($res);
var_dump($res);

输出：

array(2) {
  [0]=>
  array(4) {
    ["id"]=>
    int(1)
    ["ip"]=>
    string(10) "10.40.47.5"
    ["visited_ip"]=>
    string(11) "10.40.40.10"
    ["quota"]=>
    int(50)
  }
  [1]=>
  array(4) {
    ["id"]=>
    int(2)
    ["ip"]=>
    string(11) "10.40.47.20"
    ["visited_ip"]=>
    string(11) "10.40.40.10"
    ["quota"]=>
    int(10)
  }
}
