如何将多维数组转换为json对象[关闭]

Question

我有一个数组到json转换的问题，我有一个数组，我想将此数组转换为json对象，下面给出了所需的输出，所以任何人请帮助我。

Php阵列

    Array
(
    [0] => Array
        (
            [application_id] => 132
            [application_status] => SUBMITTED
            [reference_number] => 
            [salutation] => 
            [first_name] => 
            [middle_name] => 
            [last_name] => 
            [mother_name] => 


        )

    [1] => Array
        (
            [application_id] => 148
            [application_status] => SUBMITTED
            [reference_number] => 
            [salutation] => 
            [first_name] => 
            [middle_name] => 
            [last_name] => 
            [mother_name] => 


        )

    [2] => Array
        (
            [application_id] => 154
            [application_status] => SUBMITTED
            [reference_number] => 
            [salutation] => 
            [first_name] => 
            [middle_name] => 
            [last_name] => 
            [mother_name] => 


        )

    [3] => Array
        (
            [application_id] => 182
            [application_status] => SUBMITTED
            [reference_number] => 
            [salutation] => 
            [first_name] => 
            [middle_name] => 
            [last_name] => 
            [mother_name] => 


        )

    [4] => Array
        (
            [application_id] => 186
            [application_status] => SUBMITTED
            [reference_number] => 
            [salutation] => 
            [first_name] => 
            [middle_name] => 
            [last_name] => 
            [mother_name] => 



        )

)

将上面的数组转换为json对象，如下所示：

[
        {
            "application_id": "1",
            "application_status": "0",
            "reference_number": "/index",
            "salutation": "index",
            "first_name": "Index",
            "middle_name": "Home",
            "last_name": "1",

        },
        {
            "application_id": "1",
            "application_status": "0",
            "reference_number": "/index",
            "salutation": "index",
            "first_name": "Index",
            "middle_name": "Home",
            "last_name": "1",

        },
        {
            "application_id": "1",
            "application_status": "0",
            "reference_number": "/index",
            "salutation": "index",
            "first_name": "Index",
            "middle_name": "Home",
            "last_name": "1",

        },
        {
            "application_id": "1",
            "application_status": "0",
            "reference_number": "/index",
            "salutation": "index",
            "first_name": "Index",
            "middle_name": "Home",
            "last_name": "1",

        },
        {
            "application_id": "1",
            "application_status": "0",
            "reference_number": "/index",
            "salutation": "index",
            "first_name": "Index",
            "middle_name": "Home",
            "last_name": "1",

        },

]  

Answer 1

您想要的输出表明它是一个对象数组。 只需循环遍历它们并将每个子数组编码为json字符串，然后再次对其进行解码以获取对象：

foreach($array as $k =>$a){
    $array[$k] = json_decode(json_encode($a));
}

但是，如果你的意思是你想要一个json字符串数组，省略json_decode ：

foreach($array as $k =>$a){
    $array[$k] = json_encode($a);
}

Answer 2

你可以使用json_encode来解决这个问题吗？ 这会将传递的参数转换为JSON对象。

Answer 3

只需使用json_encode（）

<?php    
$array = Array
(
    "0" => Array
        (
            "application_id" => "132",
            "application_status" => "SUBMITTED",
            "reference_number" => "",
            "salutation" => "",
            "first_name" => "",
            "middle_name" => "",
            "last_name" => "",
            "mother_name" => ""    
        ),    
    "1" => Array
        (
            "application_id" => "148",
            "application_status" => "SUBMITTED",
            "reference_number" => "",
            "salutation" => "",
            "first_name" => "",
            "middle_name" => "",
            "last_name" => "",
            "mother_name" => ""    
        ),    
    "2" => Array
        (
            "application_id" => "154",
            "application_status" => "SUBMITTED",
            "reference_number" => "",
            "salutation" => "",
            "first_name" => "",
            "middle_name" => "",
            "last_name" => "",
            "mother_name" => ""    
        ),    
    "3" => Array
        (
            "application_id" => "182",
            "application_status" => "SUBMITTED",
            "reference_number" => "",
            "salutation" => "",
            "first_name" => "",
            "middle_name" => "",
            "last_name" => "",
            "mother_name" => ""    
        ),    
    "4" => Array
        (
            "application_id" => "186",
            "application_status" => "SUBMITTED",
            "reference_number" => "",
            "salutation" => "",
            "first_name" => "",
            "middle_name" => "",
            "last_name" => "",
            "mother_name" => ""    
        )    
);


$json = json_encode($array);

print_r($json);

?>
