我有这个数组

我需要将此转换为此数组

我试图以递归的方式做到这一点，但我碰到了墙。

我目前的代码是这样，但它并不是真的正确。

public function transform($request)
{
    $request = json_decode($request, true);

    foreach ($request as $key => $value) {
        if ($key == 'rules') {
            foreach ($value as $rKey => $rValue) {
                if (!is_array($rValue['query']['rules'])) {
                    $this->parsedRequest[$key] = $rValue['query'];
                } else {
                    $this->transform(json_encode($rValue['query']));
                }
            }
        }

        $this->parsedRequest[$key] = $value;
    }
}

这只会覆盖现有值。我无法理解它。我尝试使用array_walk_recursive，但我无法使用它。任何帮助表示赞赏。

P.S。我递归地需要这个，因为我不知道会有多少层。这些数组只是示例。

第一个数组：

array ( 'condition' => 'AND', 'rules' => array ( 0 => array ( 'type' => 'query-builder-rule', 'query' => array ( 'id' => 'transactionDate', 'field' => 'transactionDate', 'type' => 'date', 'input' => 'datepicker', 'operator' => 'equal', 'value' => '2017-05-02 00:00 - 2017-05-03 00:00', 'rule' => 'transactionDate', ), ), 1 => array ( 'type' => 'query-builder-group', 'query' => array ( 'condition' => 'OR', 'rules' => array ( 0 => array ( 'type' => 'query-builder-rule', 'query' => array ( 'id' => 'firstname', 'field' => 'firstname', 'type' => 'string', 'input' => 'text', 'operator' => 'equal', 'value' => 'Doe', 'rule' => 'firstname', ), ), 1 => array ( 'type' => 'query-builder-rule', 'query' => array ( 'id' => 'lastname', 'field' => 'lastname', 'type' => 'string', 'input' => 'text', 'operator' => 'equal', 'value' => 'Doe', 'rule' => 'lastname', ), ), 2 => array ( 'type' => 'query-builder-rule', 'query' => array ( 'id' => 'email', 'field' => 'email', 'type' => 'string', 'input' => 'text', 'operator' => 'equal', 'value' => 'Doe', 'rule' => 'email', ), ), ), ), ), ), )

第二个数组：

array ( 'condition' => 'OR', 'rules' => array ( 0 => array ( 'type' => 'query-builder-rule', 'query' => array ( 'id' => 'firstname', 'field' => 'firstname', 'type' => 'string', 'input' => 'text', 'operator' => 'equal', 'value' => 'Doe', 'rule' => 'firstname', ), ), 1 => array ( 'type' => 'query-builder-rule', 'query' => array ( 'id' => 'lastname', 'field' => 'lastname', 'type' => 'string', 'input' => 'text', 'operator' => 'equal', 'value' => 'Doe', 'rule' => 'lastname', ), ), 2 => array ( 'type' => 'query-builder-rule', 'query' => array ( 'id' => 'email', 'field' => 'email', 'type' => 'string', 'input' => 'text', 'operator' => 'equal', 'value' => 'Doe', 'rule' => 'email', ), ), ), )

在这里，我为你编写了代码。函数名称为simplify，您的数组位于$arr。

<?php
function simplify($arr) {
    if(is_array($arr))
        foreach($arr as $key => &$a) {
            if($key == 'rules') {
                if(is_array($a))
                    foreach($a as $key2 => &$a2) {
                        if(isset($a2['query'])) {
                            if(isset($a2['query']['rules'])) {
                                $a2['query'] = simplify($a2['query']);
                            }
                            $a2 = $a2['query'];
                        }
                    }
            }
        }

    return $arr;
}

$arr = array(
    'condition' => 'AND',
    'rules' => array(
        0 => array(
            'type' => 'query-builder-rule',
            'query' => array(
                'id' => 'transactionDate',
                'field' => 'transactionDate',
                'type' => 'date',
                'input' => 'datepicker',
                'operator' => 'equal',
                'value' => '2017-05-02 00:00 - 2017-05-03 00:00',
                'rule' => 'transactionDate',
            ) ,
        ) ,
        1 => array(
            'type' => 'query-builder-group',
            'query' => array(
                'condition' => 'OR',
                'rules' => array(
                    0 => array(
                        'type' => 'query-builder-rule',
                        'query' => array(
                            'id' => 'firstname',
                            'field' => 'firstname',
                            'type' => 'string',

                        'query' => array(
                            'id' => 'lastname',
                            'field' => 'lastname',
                            'type' => 'string',
                            'input' => 'text',
                            'operator' => 'equal',
                            'value' => 'Doe',
                            'rule' => 'lastname',
                        ) ,
                    ) ,
                    2 => array(

                            'type' => 'string',
                            'input' => 'text',
                            'operator' => 'equal',

                            'rule' => 'email',
                        ) ,
