Question

我有一个国家/地区的php数组，我希望根据客户的要求将其分类为特定顺序。

该数组当前是从我们无法控制的后端馈入的，如下所示：


        array(10) {
  ["AUD"]=>
  string(17) "Australian Dollar"
  ["GBP"]=>
  string(22) "British Pound Sterling"
  ["CAD"]=>
  string(15) "Canadian Dollar"
  ["DKK"]=>
  string(12) "Danish Krone"
  ["EUR"]=>
  string(4) "Euro"
  ["JPY"]=>
  string(12) "Japanese Yen"
  ["NOK"]=>
  string(15) "Norwegian Krone"
  ["RUB"]=>
  string(13) "Russian Ruble"
  ["SEK"]=>
  string(13) "Swedish Krona"
  ["USD"]=>
  string(9) "US Dollar"
}

我需要根据客户的喜好对它进行重新排序，使其类似于

        array(10) {
  ["GBP"]=>
  string(22) "British Pound Sterling"
  ["AUD"]=>
  string(17) "Australian Dollar"
  ["NOK"]=>
  string(15) "Norwegian Krone"
  ["RUB"]=>
  string(13) "Russian Ruble"
  ["USD"]=>
  string(9) "US Dollar"
  ["CAD"]=>
  string(15) "Canadian Dollar"
  ["DKK"]=>
  string(12) "Danish Krone"
  ["EUR"]=>
  string(4) "Euro"
  ["JPY"]=>
  string(12) "Japanese Yen"
  ["SEK"]=>
  string(13) "Swedish Krona"

}

我唯一想到的方法就是switch语句，

            $ordered_currencies = Array();
        ?>
        <?php foreach ($currencies as $_code => $_name): 
                switch ($_code) {
            case 'AUD':
            $ordered_currencies[0] = [$_code => $_name];
                break;
            case 'CAD':
            $ordered_currencies[1] = Array($_code => $_name);
                break;
            case 'GBP':
            $ordered_currencies[2] = Array($_code => $_name);
                break;
            case 'DKK':
            $ordered_currencies[3] = Array($_code => $_name);
                break;
            case 'EUR':
            $ordered_currencies[4] = Array($_code => $_name);
                break;
            case 'JPY':
            $ordered_currencies[5] = Array($_code => $_name);
                break;
            case 'RUB':
            $ordered_currencies[6] = Array($_code => $_name);
                break;
            case 'SEK':
            $ordered_currencies[7] = Array($_code => $_name);
                break;
            case 'USD':
            $ordered_currencies[8] = Array($_code => $_name);
                break;
        }
         endforeach; ?>

但这会返回以下格式的数组，这不是我所需要的

 array(10) {
[0]=>
  array(1) {
    ["AUD"]=>
    string(17) "Australian Dollar"
  }
  [2]=>
  array(1) {
    ["GBP"]=>
    string(22) "British Pound Sterling"
  }
  [1]=>
  array(1) {
    ["CAD"]=>
    string(15) "Canadian Dollar"
  }
.....

有什么想法吗？

您可以将客户偏好设置存储为货币代码数组，并按照此偏好设置数组的顺序从$preferences = ['AUD', 'CAD', 'GBP']; $sortedCurrencies = []; foreach ($preferences as $preference) { $sortedCurrencies[$preference] = $currencies[$preference]; }中获取值：

     if(head==NULL)
        return 0;

     while(head && fast->next!=NULL){
         fast=fast->next->next;
     }

根据用户定义的首选项对PHP数组进行排序
