将PHP数组父项移动为子项

我有一个多维PHP数组，如下所示：

  Array(
    [id] => lO2riJGekyHmjvFbASTa
    [word] => abc
    [product_id] => 1
    [variation] => Array(
      [attribute_1] => attribute-1
      [attribute_2] => attribute-2
      [attribute_3] => attribute-3
    )
  )

我喜欢的是将前两个项“id”和“word”移动为“variation”项的前两个子项，因此数组如下所示：

  Array(
    [product_id] => 1
    [variation] => Array(
      [id] => lO2riJGekyHmjvFbASTa
      [word] => abc
      [attribute_1] => attribute-1
      [attribute_2] => attribute-2
      [attribute_3] => attribute-3
    )
  )

我怎样才能做到这一点？

非常感谢

简单，只需将它们分配给

变体

，然后

取消设置

原始：

$array['variation']['id'] = $array['id'];
$array['variation']['word'] = $array['word'];
unset($array['id'], $array['word']);

原件：

$array['variation']['id'] = $array['id'];
$array['variation']['word'] = $array['word'];
unset($array['id'], $array['word']);

我也看到了上面Abracadver给出的简短回答，应该已经对你有所帮助了。如果您不想更改数组位置，请按照以下代码执行一次并重试

<?php

$arr = array("id" => "lO2riJGekyHmjvFbASTa",
    "word" => "abc",
    "product_id" => "1",
  'variation' => array('attribute_1' => "attribute-1",'attribute_2' => "attribute-2",'attribute_3' => "attribute-3")
);

foreach($arr as $id => $val){
    if($id == "word"){
        array_unshift($arr['variation'], $arr['word']);
    }
}

foreach($arr as $id => $val){
    if($id == "id"){
        array_unshift($arr['variation'], $arr['id']);
    }
}


function replaceArrayKey($array, $oldKey, $newKey){
    //If the old key doesn't exist, we can't replace it...
    if(!isset($array[$oldKey])){
        return $array;
    }
    //Get a list of all keys in the array.
    $arrayKeys = array_keys($array);
    //Replace the key in our $arrayKeys array.
    $oldKeyIndex = array_search($oldKey, $arrayKeys);
    $arrayKeys[$oldKeyIndex] = $newKey;
    //Combine them back into one array.
    $newArray =  array_combine($arrayKeys, $array);
    return $newArray;
}
$variationNew = replaceArrayKey($arr['variation'], 0, 'id');
$variationNew = replaceArrayKey($variationNew, 1, 'word');


unset($arr['id']);
unset($arr['word']);

$arr['variation'] = $variationNew;
echo "<pre>"; print_r($arr);


?>

如果我理解，您想创建另一个数组，如您所监视的第二个数组！？？如果我明白的话，你想创建另一个数组，就像你上次梦到的第二个一样！？？
