Question

我需要删除我的产品数组中类别不在控件数组内容中的所有条目。我确实在SO上看到了类似的问题，但是我没有找到可行的解决方案，而且很多问题都与简单数组而不是多维数组有关。

我的$ products数组的示例是

我的$ control数组是

Array
(
[0] => Array
    (
        [categories_id] => 163
    )


[1] => Array
    (
        [categories_id] => 179
    )

[2] => Array
    (
        [categories_id] => 274
    )

)

产品数组中的最后一项的类别值为144，不在控件数组中，因此应将其删除。

根据我尝试过的其他帖子中的信息

$products = array_flip( $products );
$products = array_diff( $products, $control );
$products = array_flip( $products );

但是当我执行print_r（$ products）时，我刚得到Array（）

var_export（$ products）

Answer 1

我建议：

// Build a single array of categories IDs, that are allowed
$categories = [];
foreach ($control as $value) {
    $categories[] = $value['categories_id'];
}

// Filter values that are not in the $categories
$result = array_filter($products, function($val) {
    return in_array($val['category'], $categories);
});

print_r($result);

Answer 2

您应该可以通过简单的array_intersect来做到这一点。

//flatten control array
$control = array_column($control, "categories_id");

// make $products associative.
$products = array_column($products, Null, "category");

//filter with array_intersect_key
$filtered = array_intersect_key($products, array_flip($control));

（可选）您可以添加array_values以删除最后一行上的关联键，例如：

//filter with array_intersect_key
$filtered = array_values(array_intersect_key($products, array_flip($control)));

如果您也想要一种衬板。

$filtered = array_values(array_intersect_key(array_column($products, Null, "category"), array_flip(array_column($control, "categories_id"))));

但这在我看来很难读懂。

根据另一个数组的内容过滤多维数组的内容
