转换 PHP 数组

Question

我有 php 数组，例如：

['AL'=>'Albania','AD'=>'Andorra','AT'=>'Austria']

我需要把它转换成

[[code=>'AL',country=>'Albania'],[code=>'AD',country=>'Andorra'],[code=>'AT',country=>'Austria']].

如何在 php 中执行此操作？

Answer 1

这应该适合你：

<?php

    $arr = ['AL'=>'Albania','AD'=>'Andorra','AT'=>'Austria'];
    $result = array();

    foreach($arr as $k => $v)
        $result[] = array("code" => $k, "country" => $v);

    print_r($result);

?>

输出：

Array ( [0] => Array ( [code] => AL [country] => Albania ) [1] => Array ( [code] => AD [country] => Andorra ) [2] => Array ( [code] => AT [country] => Austria ) )

Answer 2

PHP 脚本和您需要的输出表明您必须使用关联数组。这些数组允许在数组中使用命名键。您可以使用以下代码简单地获得所需的输出：

<?php

    $a = ['AL'=>'Albania','AD'=>'Andorra','AT'=>'Austria'];//Associative Array Declaration
    $output = array();

    foreach($a as $w => $x)//For every value in $a, it will display code and the country
        $output[] = array("code" => $w, "country" => $x);

    print_r($output);//Displaying the array output

?>
