【问题描述】：

我有这个数组...

[
 [
  [
    "name" => "Initials"
    "value" => "ROR"
  ],
  [
    "name" => "Awards"
    "value" => "Swimming"
  ],
],
[
  [
    "name" => "Initials"
    "value" => "NAL"
  ],
  [
    "name" => "Awards"
    "value" => "Cycling"
  ],
 ]
]

更改此数组的最佳方法是什么，以便我可以像这样保存它...

[
  [
    "Initials" => "ROR"
    "Awards" => "Swimming"
  ],
  [
    "Initials" => "NAL"
    "Awards" => "Cycling"
  ],
]

我已经开始做一些事情，比如循环遍历它们……但这给了我每个新数组一个数组元素。

foreach($array as $rows) {
    foreach($rows as $field) {
        $values[] = [$field['name'] => $field['value']];
    }
}

【解决方案1】：

您可以使用array_column() 来索引内部数组，指定要用作值的列和索引它的列...

$values = [];

foreach($array as $rows) {
    $values[] = array_column($rows, "value", "name");
}
print_r($values);

给...

Array
(
    [0] => Array
        (
            [Initials] => ROR
            [Awards] => Swimming
        )

    [1] => Array
        (
            [Initials] => NAL
            [Awards] => Cycling
        )

)

完美！我试过 array_column 但我想我用错了。这完美地工作。谢谢。

【解决方案2】：

你可以这样做

foreach($array as $rows) {
    foreach($rows as $field) {
        $values[] = [$field];
    }
}

或者你可以使用

$newArray = $array[0];
