我在数组到 json 的转换中遇到问题，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，所以请任何人帮助我。

php 数组

    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] => 



        )

)

像这样将上面的数组转换为 json 对象：

[
        {
            "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",

        },

]

【问题讨论】：

json_encode ?
你真的想在一个不知从何而来的 JSON 对象中有一些重复！还是只是一个错字！！
不不，它只是一个拼写错误，每个键都有不同的值。 @someOne

标签： php arrays json multidimensional-array

【解决方案1】：

您想要的输出表明它是一个对象数组。只需遍历它们并将每个子数组编码为 json 字符串，然后再次解码以获得一个对象：

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

如果您的意思是想要一个 json 字符串数组，请省略 json_decode:

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

【讨论】：

这对我有用，谢谢。

【解决方案2】：

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

【讨论】：

没有 json_encode 给出这样的数据：{ "0": { "application_id": "132", "application_status": "SUBMITTED", "reference_number": null, "salutation": null, } "1":{ "application_id": "134", "application_status": "SUBMITTED", "reference_number": null, "salutation": null, }

【解决方案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);

?>
