使用关联子数组将关联数组转换为索引数组 [英] Convert associative array to indexed array with associative subarrays

问题描述

我有一个与国家数据类似的简单关联数组:

I have a simple associative array with country data like this:

$array = array('country1' => CountryOne, 'country2' => Country Two);

如何动态将该数组转换为多个数组，例如:

How can I dynamically transform this array in a multiple array like:

array(2) {
    [0] =>  array(2) {
        ["code"] => "country1", ["name"] => "CountryOne"
    }
    [1] => array(2) {
        ["code"] => "country2", ["name"] => "CountryTwo"
    }
}

推荐答案

简单地循环通过它，并从每个键/值对创建一个新数组.

Simply loop through it and create a new array from each key/value pair.

<?php
    $array = array("country1" => "CountryOne", "country2" => "CountryTwo");

    $newArray = array();

    foreach($array as $key => $value) {
        array_push($newArray, array("code" => $key, "name" => $value));
    }

    var_dump($newArray);
?>
