如何在PHP中附加JSON文件？

Question

<?php
if(file_exists("upload.json"))
{

// For GETTING Values as an Associative Array...
$temp_array = array();
$temp_array = json_decode(file_get_contents('upload.json'),true);

 $upload_info = array('media_name'=>'b', 
 'media_category'=>'v','media_info'=>'c','media_location'=>'x','media_artist'=>'z');

 array_push($temp_array, $upload_info);

 file_put_contents('upload.json', json_encode($upload_info));
 }
else
{
$upload_info =array('media_name'=>'b',
'media_category'=>'v','media_info'=>'c','media_location'=>'x','media_artist'=>'z');

$json = json_encode($upload_info);

$file = "upload.json";

file_put_contents($file, json_encode($json));

}
?>

I can not append JSON File Together : Is there any Solutions ? Thanks in Advance .

I want JSON File in the Following Order.

{
  "upload":
    {
     "image":[
        {
         "media_name": "b",
         "media_category": "v",
         "media_info": "c",
         "media_location": "x",
          "media_artist": "z"
       },
       {
        "media_name": "b",
        "media_category": "v",
        "media_info": "c",
        "media_location": "x",
        "media_artist": "z"
       }
   ]
  }
}

What Should I do ??
