Php 向json文本字符串添加动态数据

我有这个json文本字符串

{  
    "properties_form_data": {  
        "user_id":"edhdh83883737364623",
        "property_owner":"rammstein",   
        "property_name": "rockers",   
        "property_address":"hard metal",
        "property_coordinates": true,  
        "property_type": true,  
        "property_country": true,  
        "property_district": true,  
        "property_region": "description",

        "age_restriction_for_checkin": true,
        "property_images":{"property_s3_image_links":"1.jpg,2.jpg,3.jpg","date_updated":"95356373773"},

            "date_taken":"35356373773"
        }],
        "restaurants":[{
            "album_id": "23883838dhhskk89968654s",
            "album_name":"Rammstein",
            "date_taken":"35356373773"
        }],
        "date_inserted":"hard metal", 
        "updated_on": true      
    }  
}  

  <?php
    $no = '';
$h = rand(6,99999);
$newarr = array(6,9,8,0,7);
print_r($newarr);

for ($x = 0; $x <= 10; $x++) {
         $no = '{
                    "album_id": "'.$x.'",
                    "album_name":"Rammstein",
                    "date_taken":"35356373773"
                }';
        }
$jl ='{  
    "properties_form_data": {  
        "user_id":"edhdh83883737364623",
        "property_owner":"rammstein",   
        "property_name": "'.$h.'",

        "restaurants":[{

        "updated_on": true      
    }  
}';
echo '<pre>';
echo $jl;
echo '</pre>';
    ?>

我从客户端获取了一些数据，我希望将其添加到字符串中，然后对其进行编码并将其存储起来。我接收了几个数据集作为数组，我还希望通过循环和编码生成的json文本字符串来添加这些数据集

    "properties_form_data": {

php抱怨我不能从json文本内部使用for循环，这是一个问题，因为我有几个数组要添加。如何将数组数据添加到json文本字符串中？

使用匿名函数形成json文本，并根据数组长度添加或省略最后一个元素逗号，确保生成有效的json

不要手动构建JSON。解码，添加新元素，重新编码。这能回答你的问题吗？除此之外，您试图在赋值中使用

echo

（非法），并试图使用

+

连接（混合JS和PHP语法）。？不，没有。具体地说，我想为一个非常特定的用例添加数组数据。
