如何检查给定的三个数组中的条件

Question

我有三个阵列

1. topicsSelected
2. relavantGroups
3. topicAssingned

$topicsSelected = [ "T-100","T-600"];

$relavantGroups = [[ "id" => "G-001","name" => "3 A","active"=> false ], ["id"=> "G-002","name"=> "3 B","active"=> false]  ];

$topicAssingned = [
    "G-001" => [
        "groupID" => "G-001",
        "groupName" => "3 A",
        "topics" => [
            "T-100" => [
                "topicID" => "T-100"
            ],
            "T-200" => [
                "topicID" => "T-200"
            ]
        ]
    ],
    "G-002" => [
        "groupID" => "G-002",
        "groupName" => "3 B",
        "topics" => [
            "T-400" => [
                "topicID" => "T-400"
            ],
            "T-500" => [
                "topicID" => "T-500"
            ]
        ]
    ],
];

$ topicsSelected数组值（T-100或T-600）$ topicAssingned数组中至少应有一个值，基于groupID（G-001）。 $ topicAssned主题下，topicID：T-100存在，所以Disable : D

$ topicsSelected数组值（T-100或T-600）$ topicAssingned数组中至少应有一个值，基于groupID（G-002）。 $ topic主题下的主题，主题ID：T-100和T-600不存在，所以Disable : A

预期产量：

[
     "id": "G-001",
    "name": "3 A",
    "active": false,
    "Disable" : "D"
],
[
     "id": "G-002",
    "name": "3 B",
    "active": false,
    "Disable" : "A"
]

我的守则

    foreach ($relavantGroups as &$g) {
    $found = false;
    foreach ($topicAssingned as $key => $assigned) {
        if ($key === $g["id"]) {
            $found = true;
            break;
        }
    }
    $g["disable"] = $found ? "D" : "A";
}
echo "<pre>";
print_r($relavantGroups);

我的输出

    Array
(
    [0] => Array
        (
            [id] => G-001
            [name] => 3 A
            [active] => 
            [disable] => D
        )

    [1] => Array
        (
            [id] => G-002
            [name] => 3 B
            [active] => 
            [disable] => D
        )

你可以尝试这个片段，

foreach ($relavantGroups as &$g) {
    $found = false;
    foreach ($topicAssingned as $key => $assigned) {
        if ($key === $g["id"]) {
            $temp  = array_keys($assigned['topics']); // fetching all topic ids
            $intr  = array_intersect($topicsSelected, $temp); // checking if there are any matching values between topicSelected and traversed values
            $found = (!empty($intr) ? true : false); // if found return and break
            break;
        }
    }
    $g["disable"] = $found ? "D" : "A";
}
print_r($relavantGroups);

array_intersect - 计算数组的交集 array_keys - 返回数组的所有键或键的子集

产量

Array
(
    [0] => Array
        (
            [id] => G-001
            [name] => 3 A
            [active] => 
            [disable] => D
        )

    [1] => Array
        (
            [id] => G-002
            [name] => 3 B
            [active] => 
            [disable] => A
        )

)

目前你根本不使用$topicsSelected数组 - 你只需要找到ID，然后将其标记为找到。相反，一旦找到该项目，您就需要检查该项是否在该项目的主题列表中。

由于您将ID作为$topicAssingned变量的关键，因此您无需搜索它，只需按键引用它，然后使用array_keys()提取主题列表。然后你可以使用array_intersect()检查它们是否匹配...

foreach ($relavantGroups as &$g) {
    // List of topics in assigned
    $listTopics = array_keys($topicAssingned[$g["id"]]["topics"]);
    // Check for match between selected and topics in group
    $g["disable"] = array_intersect($topicsSelected, $listTopics) ? "D" : "A";
}
echo "<pre>";
print_r($relavantGroups);
