PHP的节点移动到父数组 [英] php move nodes to parent array

问题描述

如何在不设置字段的情况下将字段数组的所有节点移到其父数组 113？

How could I move all nodes of the 'fields' array into its parent array '113', whilst unsetting 'fields' ?

    [a] => Array
    (
        [113] => Array
            (
                [title] => asdfasdfas
                [alias] => asdfasdfas
                [fields] => Array
                    (
                        [jr_streetaddress] => Array
                            (
                                [type] => text
                                [label] => Street Address
                                [data] => asdfasdffsd
                            )

                        [jr_towncity] => Array
                            (
                                [type] => text
                                [label] => Town / City
                                [data] => Nottingham
                            )
                    )
            )
     )

推荐答案

假定您的顶级数组（ $ something ['a'] ）是变量 $ a ：

Assuming your top level array ($something['a']) is the variable $a:

foreach($a as $key => $values){
  if(isset($values['fields']))
    {
       $a[$key] = array_merge($a[$key], (array) $values['fields']);
       unset($a[$key]['fields']);
    }
}

或者，如果您不想击中每个数组元素在 $ a 中，您可以删除循环并用 $ a [113]代替 $ values ] 和 $ key 和 113 。

Alternatively, if you dont want to hit every array element in $a you can just remove the loop and substitute $values with $a[113] and $key with 113.

还要注意将fields元素强制转换为数组，如果不是（array）$ values ['fields']

Also note the casting for the fields element to an array, jsut in case it isnt one with (array) $values['fields']
