Question

我有一个像这样的数组$testing：

Array ( 
    [CUST_TYPE] => 
        Array ( 
            [0] => Family 
            [1] => Regular 
            [2] => Corporate 
            [3] => Premium ) 
    [TOTAL_BALANCE] => 
        Array ( 
            [0] => 420946131.01 
            [1] => 41272033223.93 
            [2] => 38873647942.4 
            [3] => 10465337565.61 ) 
        )

我需要将这个数组转换（打印）成这样的东西：

{
cust_type : Family,
balance : 420946131.01
},
{
cust_type : Regular ,
balance : 41272033223.93
},
and so on..

以下是我使用的简单foreach，但它只能打印cust_type或balance

$cols = array_keys($testing);

foreach ($testing[$cols[1]] as $i => $j) {
        echo '{cust_type : ' . $j . 
             ', balance : ' . $<What should I print??> . '},';        
    }

请帮助。谢谢。

Answer 1

考虑这个片段，

$scope.showMe=function(){
  $scope.isVisible=!$scope.isVisible;
}

将输出，

for($i=0; $i<count($your_array['CUST_TYPE']); $i++)
{
    $required[] = [ 'cust_type' => $your_array['CUST_TYPE'][$i],
                    'balance' => $your_array['TOTAL_BALANCE'][$i] ];
}

$required = json_encode($required);

对于其他格式，您可以使用array_combine()创建一个数组，其中第一个参数作为键，第二个作为值，

您指定的格式为[{"cust_type":"Family","balance":420946131.01},{"cust_type":"Regular","balance":41272033223.93},{"cust_type":"Corporate","balance":38873647942.4},{"cust_type":"Premium","balance":10465337565.61}]因此，json会为您执行此操作，

json_encode()

现在，$required = array_combine($your_array['CUST_TYPE'], $your_array['TOTAL_BALANCE']); $required = json_encode($required);是您想要的值的字符串。是的，

$required

注意：确保输入数组中的{"Family":420946131.01,"Regular":41272033223.93,"Corporate":38873647942.4,"Premium":10465337565.61}和$your_array['CUST_TYPE']数组中的成员数相同。否则你会看到警告。

使用array_map（PHP 4＆gt; = 4.0.6，PHP 5）

$json = json_encode(array_map(function($a,$b){ return array("cust_type"=>$a,"balance"=>$b);},$array["CUST_TYPE"],$array["TOTAL_BALANCE"]));

<?php

$array = array( 
            "CUST_TYPE" => array( 
                                'Family', 
                                'Regular', 
                                'Corporate', 
                                'Premium' 
                               ), 
            "TOTAL_BALANCE" => array( 
                                420946131.01, 
                                41272033223.93,
                                38873647942.4 ,
                                10465337565.61 
                              )
             );


// PHP 4,5
$json = json_encode(array_map(function($a,$b){ return array("cust_type"=>$a,"balance"=>$b);},$array["CUST_TYPE"],$array["TOTAL_BALANCE"]),JSON_PRETTY_PRINT);

// Input
print_r($array);

// Output
print $json."\n";

?>
