Consider using FILTER_CALLBACK. In this way, you can write a callback function that itself uses the filter extension, thus providing a recursive ability.

考虑使用FILTER_CALLBACK。通过这种方式，您可以编写一个本身使用过滤器扩展的回调函数，从而提供递归功能。

function validate_array($args) {
    return function ($data) use ($args) {
        return filter_input_array($data, $args);
    };
}

This will generate the callback functions.

这将生成回调函数。

$args = array(
    'user' => array(
        'filter' => FILTER_CALLBACK,
        'options' => validate_array(array(
            'age' => array('filter' => FILTER_INPUT_INT),
            'email' => array('filter' => FILTER_INPUT_EMAIL)
        ))
    )
);

This is what the config array would then look like.

这就是配置数组的样子。

Do not hesitate to pat me on the back for this one because I am quite proud of it.

不要犹豫要拍我的背，因为我为此感到自豪。

Take an arg array that looks like this. Slashes indicate depth.

拿一个看起来像这样的arg数组。斜线表示深度。

$args = array(
    'user/age' => array('filter' => FILTER_INPUT_INT),
    'user/email' => array('filter' => FILTER_INPUT_EMAIL),
    'user/parent/age' => array('filter' => FILTER_INPUT_INT),
    'foo' => array('filter' => FILTER_INPUT_INT)
);

Assume your data looks something like this.

假设您的数据看起来像这样。

$data = array(
    'user' => array(
        'age' => 15,
        'email' => 'foo@gmail.com',
        'parent' => array(
            'age' => 38
        )
    ),
    'foo' => 5
);

Then, you can generate an array of references that map keys such as 'user/age' to $data['user']['age']. In final production, you get something like this:

然后，您可以生成一个引用数组，将“user / age”等键映射到$ data ['user'] ['age']。在最终的制作中，你得到这样的东西：

function my_filter_array($data, $args) {
    $ref_map = array();
    foreach ($args as $key => $a) {
        $parts = explode('/', $key);
        $ref =& $data;
        foreach ($parts as $p) $ref =& $ref[$p];
        $ref_map[$key] =& $ref;
    }
    return filter_var_array($ref_map, $args);
}

var_dump(my_filter_array($data, $args));

Now the only question is how you deal with the mismatch between the validation record and the original data set. This I cannot answer without knowing how you need to use them.

现在唯一的问题是如何处理验证记录与原始数据集之间的不匹配。如果不知道如何使用它们，我无法回答。
