$con=mysqli_connect($host,$user,$password,$database)or die("Unable to connect");
if($_SERVER["REQUEST_METHOD"]=="POST")
{


    if(isset($_POST['OrderSummary']))
    {

        $data=$_POST['OrderSummary'];
        $json=json_decode($data,true);
        $file='text.txt';
        $result=file_put_contents($file,$json);


            $response["success"]=1;
            $response["message"]="done";


    }
    else
    {
        $response["success"]=0;
        $response["message"]="parameters not correctl formatted";
    }

    echo json_encode($response);
}
    ?>

How should we know what you are doing wrong if we don't know your code? Please read [ask]. — Felix Kling, Oct 18 '17 at 06:06
sorry i just updated code please see the code and help me out — atul kumar, Oct 18 '17 at 06:09
Well... You are `json_decoding` a (unknown) vaue with the second parameter `true`. So it's pretty safe to assume `$json` is in fact an array and not a `json`-string — DarkBee, Oct 18 '17 at 06:12
first the array was getting written to the file but now it is retruning this — atul kumar, Oct 18 '17 at 06:19
As your `json_decode` returns an array and not null it's safe to assume you just can write `$result=file_put_contents($file, $_POST['OrderSummary']);` as `$_POST['OrderSummary']` contains a valid `json`-string — DarkBee, Oct 18 '17 at 06:35

Your $json is an multidimension array, while function file_put_contents() only accept a string, array, or stream as the data content. When the array is one dimension array, it store each element of the array. When the array is multidimension array, it will cause,

PHP Notice: Array to string conversion in /home/xxxxx/test.php on line xx

You can test simple demo, which will store ArrayArrayArray in the aaa.txt file. And the number of 'Array' is lenth of the multidimension array count([[1,2,3,4],[2],[3]]) which is 3.

<?php
file_put_contents("aaa.txt", [[1,2,3,4],[2],[3]]);

the problem is solved i want to know how can i read it's element and store it in the database – atul kumar Oct 18 '17 at 06:58
This answer can't be true as OP does `file_put_contents($file, json_decode($_POST['OrderSummary'], true));`. If `$_POST['OrderSummary']` was indeed a (multidimensional) array the output in his file would empty as [`json_decode([[],], true)`](https://ideone.com/ki9o12) returns `NULL` – DarkBee Oct 18 '17 at 07:17
@DarkBee Here I make a mistake, I just want to say OP use a multidimension array as the parameter of `file_put_contents` which cause the issue. – LF00 Oct 18 '17 at 07:23
@KrisRoofe True, but storing a multidimensional array in a file will only output one `Array` in it. OP is prolly using `FILE_APPEND` in his/her original code. Nonetheless OP ain't clear on what he/she want. – DarkBee Oct 18 '17 at 07:30
@DarkBee You can test the demo in the answer. – LF00 Oct 18 '17 at 07:31
@DarkBee the number of `Array` is the first dimension. In you demo code, the first dimension of your array is 1. – LF00 Oct 18 '17 at 07:43
@KrisRoofe Point taken there – DarkBee Oct 18 '17 at 07:49

Check for print_r($_POST['OrderSummary']) before writing into file. Must be array,

Should be a comment – DarkBee Oct 18 '17 at 06:22
thanks for your suggestion as i want to read the contents of the array and then store it in the database could you suggest me anyway to do it ? – atul kumar Oct 18 '17 at 06:41
Frankly , i dont know nothing about the content of $_POST['OrderSummary'], If you want to get the whole content as string , use implode on this array. – Blesson Christy Oct 18 '17 at 06:45
