在PHP中，如何迭代数组并动态更改密钥？

我有一个数组

$people

。当我打印（$people）时，我得到以下结果：

[people] => Array
(
  [500] => Array
          (
              [firstName] => Fred
              [age] => 19
          )

  [501] => Array
          (
               [firstName] => Bob
               [age] => 12
          )
  [502] => Array
          (
               [firstName] => Steve
               [age] => 52
          )
)

我想改变所有的键，使其看起来更“正常”，从0开始，然后是1、2等等。我如何才能做到这一点？为了澄清，我希望生成的数组如下所示：

    [people] => Array
(
  [0] => Array
          (
              [firstName] => Fred
              [age] => 19
          )

  [1] => Array
          (
               [firstName] => Bob
               [age] => 12
          )
  [2] => Array
          (
               [firstName] => Steve
               [age] => 52
          )
)

foreach ($people as $value) {
  $people_new[] = $value;
}

就这样:

    [people] => Array
(
  [0] => Array
          (
              [firstName] => Fred
              [age] => 19
          )

  [1] => Array
          (
               [firstName] => Bob
               [age] => 12
          )
  [2] => Array
          (
               [firstName] => Steve
               [age] => 52
          )
)

foreach ($people as $value) {
  $people_new[] = $value;
}

内置函数将只从数组中获取值，忽略键，而是返回从零重新编号的数组

$people = array_values($people);

试试这个

$people['people'] = array_values($people['people']);
print_r($people);

不要迭代，只需使用

array\u values（）

即可为您重置键：

$people['people']=array\u values（$people['people']）
