如何搜索具有多个搜索条件的多维数组? [英] How to search an multi-dimensional array with multiple search conditions?

问题描述

我想在条件为两个值的多维数组中搜索键.

I want to search a key in a multidimensional array with two values in the condition.

我知道如何使用单个搜索条件搜索多维数组:

I know how to search a multi-dimensional array with a single search condition:

$key = array_search($journee, array_column($data,'journee'));

但不止于此.这是我的阵列设置:

but not more than that. Here is my array setup:

Array
(
    [0] => Array
        (
            [pseudo] => titi
            [journee] => 11
            [pts] => 3
        )

    ...
    [10] => Array
        (
            [pseudo] => test
            [journee] => 10
            [pts] => 6
        )

    [11] => Array
        (
            [pseudo] => test
            [journee] => 11
            [pts] => 4
        )

)

如果我只将 11 放在 array_search 中，并且对于 array_column 键，则将 journee 返回0.

If I only put 11 in array_search and for array_column the key journee, it will return 0.

我也想在搜索条件中添加 pseudo (应该在键 journee 和 pseudo 中搜索特定值).

I want to add pseudo in the search condition too (the keys journee and pseudo should be searched for a specific values).

我该怎么做?

推荐答案

使用一个简单的功能是不可能的.

With one simple function it's not possible.

以下是两个的解决方案:

$search = ['pseudo' => 'test', 'journee' => 10];
$keys = array_keys(
    array_filter(
        $array,
        function ($v) use ($search) { return $v['pseudo'] == $search['pseudo'] && $v['journee'] == $search['journee']; }
    )
);
$key = $keys[0];

但是，如果您只需要找到一个键，我建议您使用 foreach & break ，因为您不必遍历所有值数组(使用 array_filter 会发生这种情况)并在找到某些数据后立即停止:

But if you need to find one key only I advise to use foreach & break, because you don't have to iterate over all array of values (what will happen with using array_filter) and stop immediately when certain data is found:

$key = false;
$search = ['pseudo' => 'test', 'journee' => 10];
foreach ($array as $k => $v) {
    if ($v['pseudo'] == $search['pseudo'] && $v['journee'] == $search['journee']) {
        $key = $k;
        // key found - break the loop
        break;
    }
}
