Question

很抱歉可能会提出愚蠢的问题，但确实需要您的帮助。我有数组：

{"code":200,"message":"OK","0":{"title":"Green peppercorn and lemongrass coconut broth","media":"\/posts\/images\/84709.jpg"},"1":{"title":"Green peppercorn and lemongrass coconut broth","media":"\/posts\/images\/84709.jpg"}}

并且需要实现以下目标：

{"code":200,"message":"OK","records":[{"title":"Green peppercorn and lemongrass coconut broth","media":"\/posts\/images\/84709.jpg"},{"title":"Green peppercorn and lemongrass coconut broth","media":"\/posts\/images\/84709.jpg"}]}

请让我知道如何使用PHP ...它曾经是我与array_merge($message, $records);合并的两个数组

谢谢

Answer 1

如果您想继续进行json响应，则可以像这样创建一个新数组，但是此示例仅适用于您在问题中提到的json：

<?php
$array = json_decode('{"code":200,"message":"OK","0":{"title":"Green peppercorn and lemongrass coconut broth","media":"\/posts\/images\/84709.jpg"},"1":{"title":"Green peppercorn and lemongrass coconut broth","media":"\/posts\/images\/84709.jpg"}}
',true);

$newArray = array(); // initialize new array 
foreach ($array as $key => $value) {
    if(is_array($value))    { // if having array
        $newArray['records'][] = $value;
    }
    else{
        $newArray[$key] = $value;
    }
}
echo json_encode($newArray);
?>

结果：

{"code":200,"message":"OK","records":[{"title":"Green peppercorn and lemongrass coconut broth","media":"\/posts\/images\/84709.jpg"},{"title":"Green peppercorn and lemongrass coconut broth","media":"\/posts\/images\/84709.jpg"}]} Second, if you are mergin two array `array_merge($message, $records);`

第二个解决方案（推荐），如果您要合并两个数组并要添加新索引records，则还可以通过添加records索引来修改：

$newArray = $message;
$newArray['records'] = $records;
echo json_encode($newArray);

Answer 2

如果您需要短代码（一个字符串，两个带有$ result声明）

$json = '{"code":200,"message":"OK","0":{"title":"Green peppercorn and lemongrass coconut broth","media":"\/posts\/images\/84709.jpg"},"1":{"title":"Green peppercorn and lemongrass coconut broth","media":"\/posts\/images\/84709.jpg"}}';
$result = [];
foreach(json_decode($json,true) as $k=>$v) if(is_array($v)){$result["records"][]=$v;} else {$result[$k]=$v;};

请确保使用您的json更改$ json

结果（漂亮打印）：

{
    "code": 200,
    "message": "OK",
    "records": [
        {
            "title": "Green peppercorn and lemongrass coconut broth",
            "media": "\/posts\/images\/84709.jpg"
        },
        {
            "title": "Green peppercorn and lemongrass coconut broth",
            "media": "\/posts\/images\/84709.jpg"
        }
    ]
}

将阵列合并为一组
