如何使用php创建嵌套的JSon

How do I create a JSON like this with PHP? I am trying to convert a dynamic data and save it into a MySQL database.

如何使用PHP创建这样的JSON？我正在尝试转换动态数据并将其保存到MySQL数据库中。

{
"fbd49440-a5a1-48be-b13e-e8efddad3588": {
    "0": {
        "value": "dsfrasdf5464356dfs hdhfg dfgh"
    }
},
"0fc71cea-5609-40a7-a1d2-b78139660f8f": {
    "0": {
        "value": "50"
    }
},
"73936e70-4329-4aba-b47c-42c64ced420c": {
    "0": {
        "file": "\/components\/com_djclassifieds\/images\/item\/25_juliet_ibrahim.jpg",
        "uniqid": "59a352b96773325",
        "title": "",
        "file2": "",
        "overlay_effect": "",
        "caption": "",
        "width": "",
        "height": ""
    },
"ac00b95e-9eeb-4035-bf4a-ff206319b2d6": {
    "0": {
        "value": "members-in-good-standing-2014",
        "text": "",
        "target": "0",
        "custom_title": "",
        "rel": ""
    }
},
"69072346-fe4c-489e-8e2b-5a7d7409fd44": {
    "0": {
        "value": "34"
    }
}
}

I tried the code below but it did not give me the result I want.

我尝试了下面的代码，但它没有给我我想要的结果。

$json = (
"fbd49440-a5a1-48be-b13e-e8efddad3588"=> (
    $array1
),
"0fc71cea-5609-40a7-a1d2-b78139660f8f"=> (
    $array2
),
"73936e70-4329-4aba-b47c-42c64ced420c"=> (
    $array3
    ),
"ac00b95e-9eeb-4035-bf4a-ff206319b2d6"=> (
    $array4
),
"69072346-fe4c-489e-8e2b-5a7d7409fd44"=> (
    $array5
)
)

echo json_encode($json);

I will be glad if someone could help me, thank you

如果有人能帮助我，我会很高兴，谢谢

json_encode will take multiple types of valid data and try to encode them into a json representation of it. It does require that the input is valid.

json_encode将获取多种类型的有效数据，并尝试将它们编码为json表示形式。它确实要求输入有效。

The code you have pasted has multiple syntax errors, and we cannot tell what is in your $array1. $array2, $array3, $array4, $array5. However a couple of changes (and assuming your $arrays are actual arrays) has your code working.

您粘贴的代码有多个语法错误，我们无法分辨$ array1中的内容。 $ array2，$ array3，$ array4，$ array5。但是，一些更改（并假设您的$数组是实际数组）使您的代码正常工作。

There are also bitmask options in the form of JSON Constants that will define how your JSON should be stored.

还有JSON常量形式的位掩码选项，它们将定义如何存储JSON。

$array = array( "data" => "value");  // dummy array to show data working

$json = array( //defined the following as an array
    "fbd49440-a5a1-48be-b13e-e8efddad3588"=> array( //notice each of these are now defined as arrays
        $array
    ),
    "0fc71cea-5609-40a7-a1d2-b78139660f8f"=> array(
        $array
    ),
    "73936e70-4329-4aba-b47c-42c64ced420c"=> array(
        $array
    ),
    "ac00b95e-9eeb-4035-bf4a-ff206319b2d6"=> array(
        $array
    ),
    "69072346-fe4c-489e-8e2b-5a7d7409fd44"=> array(
        $array
    )
); //added semicolon to end the declaration

echo json_encode($json, ( JSON_FORCE_OBJECT + JSON_PRETTY_PRINT ) ); 
// added JSON_FORCE_OBJECT and JSON_PRETTY_PRINT 
// As bitmask options, they return a constant to give `json_encode` instructions
// JSON_FORCE_OBJECT => 16, JSON_PRETTY_PRINT => 128 
// JSON_FORCE_OBJECT + JSON_PRETTY_PRINT = 16 + 128 = 144
// json_encode( $array, ( JSON_FORCE_OBJECT + JSON_PRETTY_PRINT ) = json_encode ($array, 144);

Returns

{"fbd49440-a5a1-48be-b13e-e8efddad3588":{"0":{"data":"value"}},"0fc71cea-5609-40a7-a1d2-b78139660f8f":{"0":{"data":"value"}},"73936e70-4329-4aba-b47c-42c64ced420c":{"0":{"data":"value"}},"ac00b95e-9eeb-4035-bf4a-ff206319b2d6":{"0":{"data":"value"}},"69072346-fe4c-489e-8e2b-5a7d7409fd44":{"0":{"data":"value"}}}

{ “fbd49440-a5a1-48be-b13e-e8efddad3588”：{ “0”：{ “数据”： “值”}}， “0fc71cea-5609-40a7-a1d2-b78139660f8f”：{ “0”：{ “数据” ： “值”}}， “73936e70-4329-4aba-b47c-42c64ced420c”：{ “0”：{ “数据”： “值”}}， “ac00b95e-9eeb-4035-bf4a-ff206319b2d6”：{“0 “：{” 数据 “：” 值 “}}，” 69072346-fe4c-489e-8e2b-5a7d7409fd44 “：{” 0 “：{” 数据 “：” 值“}}}

Array of Arrays in your json data.

json数据中的数组数组。

If you want it to print the index of each result, that needs to be treated as an array as well. Simple enough to understand when there are multiple pairs in the result, less intuative when the result is one pair.

如果您希望它打印每个结果的索引，那么也需要将其视为数组。简单到足以理解结果中有多个对时，结果是一对时不那么直观。

$array1 = array( "data" => "value");
echo json_encode($array1, JSON_FORCE_OBJECT );
//would return
//{"data":"value"}

$array2 = array( 
    array( "data" => "value" ),
    array( "data" => "value" )
    );
echo json_encode($array2, JSON_FORCE_OBJECT );
// would return
// {"0":{"data":"value"},"1":{"data":"value"}}

$array3 = array( 
    array( "data" => "value" )
    );
echo json_encode($array3, JSON_FORCE_OBJECT );
// would return
// {"0":{"data":"value"}}
