JSON data revceiving PHP

The server receives from URL post string as below:

{
    "head": {
        "comm": 7,
        "compress": false,
        "ms": 1451029423348,
        "encrypt": false,
        "version": 2
    },
    "body": {
        "data1": 0,
        "data2": 59,
        "data3": -40,
        "data4": 0,
        "data5": 0,
    }
}

I have PHP file as below need to receive JSON format data from URL or java app sending post to server. Using server PHP ver 5.4.45, I can't change it.

$json = file_get_contents('php://input'); 
$string = get_magic_quotes_gpc() ? stripslashes($json) : $json;
$object = json_decode($string);
var_dump($object);

then i want to put to array each item in to array into $data variable each fields into $data array

I always receiving NULL , What can be the problem ?

try this:

$json = file_get_contents('php://input'); 
$string = get_magic_quotes_gpc() ? stripslashes($json) : $json;
$object = json_decode($string);

By using foreach function walk thru object elements and typecast them as an array

 foreach($object as $k=>$v){
        $data[$k] = (array)$v;
    }

and the result will be as follows:

    Array
(
    [head] => Array
        (
            [comm] => 7
            [compress] => 
            [ms] => 1451029423348
            [encrypt] => 
            [version] => 2
        )

    [body] => Array
        (
            [data1] => 0
            [data2] => 59
            [data3] => -40
            [data4] => 0
            [data5] => 0
        )

)

If, as you say, $json is NULL, the comma after "data5" is only because of text that was cut to make pasted code shorter, and you're using PHP <5.6 then according to http://php.net/manual/en/wrappers.php.php it could only be that either:

  • you're reading php://input multiple times (if not you then maybe a framework you're using or whatever);
  • the sender is passing data to you as multipart/form-data, which php://input cannot read.

The JSON data is not correct. Try after removing the , after "data": 0.
Correct JSON : 

{
  "head": {
      "comm": 7,
      "compress": false,
      "ms": 1451029423348,
      "encrypt": false,
      "version": 2
  },
  "body": {
      "data1": 0,
      "data2": 59,
      "data3": -40,
      "data4": 0,
      "data5": 0
  }
}

If I paste your json here: http://jsonlint.com/ it gives a "Error: Parse error on line 14:"

Maybe it helps when you remove the comma after "data5": 0,
