使用 PHP 中的变量取消设置数组

Question

这是我的阵列样本：

 Array

    (
        [productId] => 7740792
        [productCode] => 1019534
        [productPrice] => Array
            (
                [current] => Array
                    (
                        [value] => 150
                        [text] => £150.00
                    )

                [previous] => Array
                    (
                        [value] => 0

                [1] => Array
                    (

我想从整个数组中 delete/unset "productPrice"、"sku" 和 "price"。 到目前为止我用过这个：

unset($alldata[0]['variants'][0]['price']);
unset($alldata[0]['variants'][1]['price']);

但是数组发生了变化并且有数千个条目，因此像这样对 unset 进行编码并不容易。我是 PHP 的新手，我已经尽我所能地搜索了数组函数，但没有找到合适的东西。

Answer 1

unset ($alldata['productPrice']);

foreach ($alldata['variants'] as $key => $value) {
    unset (
        $alldata['variants'][$key]['price'], 
        $alldata['variants'][$key]['sku']
    );
}
