Php 将JSON响应转换为特定格式？

我无法以某种格式打印JSON。我正在尝试嵌套数组格式的值。 我的PHP代码是

while ($stmtPGBeds->fetch()) {
    $PGBEDS[$count] = array('pgbedid' => $bedid, 'roomnum'=>$roomnum, 
     'roomtype'=>$roomtype, 'spacetype'=>$spacetype, 'price'=>$price,
     'deposit'=>$deposit, 'status'=>$status, 'assetid'=>$assetid);
    $count++;
}

哪个输出*********

"beds": [
        {
            "bedid": "PGB050418154448673",
            "roomnum": "1",
            "roomtype": "Bedroom",
            "spacetype": "Single",
            "price": "7500",
            "deposit": "10000",
            "status": "0",
            "assetid": "AST050418051246344"
        },
        {
            "bedid": "PGB050418154448119",
            "roomnum": "2",
            "roomtype": "Bedroom",
            "spacetype": "Sharing",
            "price": "5500",
            "deposit": "10000",
            "status": "0",
        }
]

但我想以以下格式打印： 格式如下所示

"beds": [
        {
            "roomnum": "1",
            "roomtype": "Bedroom",
            "spacetype": "Single",
            "assetid": "AST050418051246344"
            "beds": [
                  {
                        "bedid": "PGB050418154448673",
                        "price": "7500",
                        "deposit": "10000",
                        "status": "0",
                  },
                  {
                        "bedid": "PGB050418154448673",
                        "price": "7500",
                        "deposit": "10000",
                        "status": "0",
                  }
             ]
        },
        {
            "roomnum": "2",
            "roomtype": "Bedroom",
            "spacetype": "Single",
            "assetid": "AST050418051246344"
            "beds": [
                  {
                        "bedid": "PGB050418154448673",
                        "price": "7500",
                        "deposit": "10000",
                        "status": "0",
                  },
                  {
                        "bedid": "PGB050418154448673",
                        "price": "7500",
                        "deposit": "10000",
                        "status": "0",
                  }
             ]
        }
]

如何使用PHP？

我建议您将房间标识作为数组键，并利用循环中存在的

数组键。见下例：

$response_data = array(
    array("roomnum"=>1, "bedid"=>1, "roomtype"=>"bedroom", "spacetype"=>"single", "price"=>7500, "desposit"=>10000, "status"=>0, "asset_id"=>"AST050418051246344"),
    array("roomnum"=>1, "bedid"=>2, "roomtype"=>"bedroom", "spacetype"=>"single", "price"=>7500, "desposit"=>10000, "status"=>0, "asset_id"=>"AST050418051246345"),
    array("roomnum"=>2, "bedid"=>1, "roomtype"=>"bedroom", "spacetype"=>"single", "price"=>8500, "desposit"=>10000, "status"=>0, "asset_id"=>"AST050418051246346"),
    array("roomnum"=>2, "bedid"=>2, "roomtype"=>"bedroom", "spacetype"=>"single", "price"=>8500, "desposit"=>10000, "status"=>0, "asset_id"=>"AST050418051246347"),
    array("roomnum"=>2, "bedid"=>3, "roomtype"=>"bedroom", "spacetype"=>"single", "price"=>8500, "desposit"=>10000, "status"=>0, "asset_id"=>"AST050418051246348")
);

$output = array();
foreach ($response_data as $value) 
{
    if ( ! array_key_exists($value["roomnum"], $output))
    {
        // lets create a new room 
        $output[$value["roomnum"]] = array(
            "roomnum"=>$value["roomnum"], 
            "roomtype"=>$value["roomtype"], 
            "spacetype"=>$value["spacetype"],
            // ... insert all your room informations here
            // ... 
            "beds"=>array()  // <<-- and create an empty array to store your beds later     

        );
    }

    // now create the array containing all the bed informations
    $bed_data = array(
        "bedid"=>$value["bedid"], 
        "price"=>$value["price"],
        "desposit"=>$value["desposit"],
        "status"=>$value["status"]
    );


    // ... and push it to the already created beds array 
    $output[$value["roomnum"]]["beds"][] = $bed_data; 
}

echo "<pre>".print_r($output, true)."</pre>";

$response\u data=array(
数组（“roomnum”=>1，“bedid”=>1，“roomtype”=>“卧室”，“spacetype”=>“单人房”，“价格”=>7500，“desposit”=>10000，“状态”=>0，“资产id”=>“AST050418051246344”），
数组（“roomnum”=>1，“bedid”=>2，“roomtype”=>“卧室”，“spacetype”=>“单人房”，“价格”=>7500，“desposit”=>10000，“状态”=>0，“资产id”=>“AST050418051246345”），
数组（“roomnum”=>2，“bedid”=>1，“roomtype”=>“卧室”，“spacetype”=>“单人房”，“价格”=>8500，“desposit”=>10000，“状态”=>0，“资产id”=>“AST050418051246346”），
数组（“roomnum”=>2，“bedid”=>2，“roomtype”=>“卧室”，“spacetype”=>“单人房”，“价格”=>8500，“desposit”=>10000，“状态”=>0，“资产id”=>“AST050418051246347”），
数组（“roomnum”=>2，“bedid”=>3，“roomtype”=>“卧室”，“spacetype”=>“单人房”，“价格”=>8500，“desposit”=>10000，“状态”=>0，“资产id”=>“AST050418051246348”）
);
$output=array（）；
foreach（$response\u数据为$value）
{
如果（！array_key_存在（$value[“roomnum”]，$output））
{
//让我们创建一个新房间
$output[$value[“roomnum”]=array(
“roomnum”=>$value[“roomnum”]，
“roomtype”=>$value[“roomtype”]，
“spacetype”=>$value[“spacetype”]，
//…在此处插入您的所有房间信息
// ... 
“床”=>array（）/$value[“价格”]，
“desposit”=>$value[“desposit”]，
“状态”=>$value[“状态”]
);
//…并将其推送到已创建的床阵列
$output[$value[“roomnum”][“beds”][]=$bed\u数据；
}
echo“.print_r（$output，true）。”；
您尝试了什么？您需要创建一个新数组，遍历现有数组，并将每个条目排序到父/子关系中。非常好。谢谢。
