如何在PHP中简化数组

Question

我在数组下面，我想简化数组以添加检查产品数量的逻辑

数组如下：-

$conditions = Array
    (
        [type] => Magento\SalesRule\Model\Rule\Condition\Combine
        [attribute] => 
        [operator] => 
        [value] => 1
        [is_value_processed] => 
        [aggregator] => all
        [conditions] => Array
            (
                [0] => Array
                    (
                        [type] => Magento\SalesRule\Model\Rule\Condition\Product\Found
                        [attribute] => 
                        [operator] => 
                        [value] => 1
                        [is_value_processed] => 
                        [aggregator] => all
                        [conditions] => Array
                            (
                                [0] => Array
                                    (
                                        [type] => Magento\SalesRule\Model\Rule\Condition\Product
                                        [attribute] => category_ids
                                        [operator] => ==
                                        [value] => 5
                                        [is_value_processed] => 
                                    )

                                [1] => Array
                                    (
                                        [type] => Magento\SalesRule\Model\Rule\Condition\Product
                                        [attribute] => category_factor
                                        [operator] => ==
                                        [value] => 13
                                        [is_value_processed] => 
                                    )                                                         

                            )

                    )

                [1] => Array
                    (
                        [type] => Magently\CustomerRule\Model\Rule\Condition\Customer
                        [attribute] => product_qty
                        [operator] => >=
                        [value] => 99
                        [is_value_processed] => 
                    )

            )

    )

我要检查attribute operator和value，如下所示：

if(product_qty >= 99){
//do your stuff
}

请帮助我简化此数组以添加我的条件以出于某些目的检查产品数量。

Answer 1

如果我正确理解您的问题。

您可以像这样使用数组索引：

foreach($conditions['conditions'] as $condition){

    if($condition['attribute'] == 'product_qty' && $condition['value']  >= 99 ){
        //do your stuff
    }

}

此代码检查attribute等于product_qty且此项的value等于99以上。条件为true。

Answer 2

我认为您最好创建一个将数组作为输入的函数。 它将为每个提及的ttrasn做一个

foreach($conditions['conditions'] as $condition){

    if($condition['attribute'] == 'product_qty' && $condition['value']  >= 99 ){
        //do your stuff
    }

}

但是，如果$ condition是一个数组，请对该数组递归调用同一函数。

Answer 3

您没有一种简单的方法可以与存储在值中的运算符进行比较，因此您需要自己编写函数。一个简单的 day | d01 | d02 | d03 | d04 | d05 | d06 | d07 | d08 | d09 | d10 | d11 | d12 | d13 | d14 | d15 | d16 | d17 | d18 | d19 | d20 | d21 | d22 | d23 -----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+----- 0 | 0 | 0 | 333 | 0 | 777 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 就可以完成这项工作：

switch

要评估您的整体情况，可以使用递归：

• 如果是与值的比较，请使用上面编写的函数
• 如果是聚合，请评估所有子项并定义聚合规则：

这里是骨架：

function compareValue($variable, $operator, $value){
    switch($operator)
    {
        case '==' : return $variable == $value ; break ;
        case '>=' : return $variable >= $value ; break ;
        /* add all possibilities here */
        default : throw new RuntimeException("Undefined operator '$operator'");
    }
}
