解析json_decoded php数组的最佳方法

Question

what would be the best way to parse stringified one dimensional array?

input array

$inputArray = array(
  "id" => "foo",
  "name" => "bar",
  "money[0][amount]" => 30,
  "money[0][countryCode]" => "US",
  "money[1][amount]" => 25,

desired output array

$outputArray = array(
  "id" => "foo",
  "name" => "bar",
  "money" => array(
    [0] => array(
      "amount" => 30,
      "countryCode" => "US"
    ),
    [1] => array(
      "amount" => 25,
      "countryCode" => "CA"
    ),
  ),
)

Answer 1

You can convert your array in a query url and parse it ... like this

<?php

$inputArray = array(
  "id" => "foo",
  "name" => "bar",
  "money[0][amount]" => 30,
  "money[0][countryCode]" => "US",
  "money[1][amount]" => 25,
  "money[1][countryCode]" => "CA",
);

$url = http_build_query($inputArray);
parse_str($url, $outputArray);

print_r($outputArray);
