the actual json txt file content is similar to this:

[ 
{ "name": "Video 0", "comment": "3RtYLZaUUdU" }, 
{ "name": "Video 1", "comment" : "QrIGoya6BcE" }, 
{ "name":"Video 2", "comment": "KQbr2OGydJU" } 
]
;

<pre>$post_data = $_POST['data'];  //user comment input text
$file = "newfile.txt";  //actual json text file, the content is above
$content = file_get_contents($file);
$arr =(json_decode($content, true)); //converts json to php associative array
print_r($arr);
echo "<br><br>";
$AssArr =array(
        "name" => "Video 3",
        "comment" => $post_data, );
array_push($arr, $AssArr);
print_r($arr);

$json = json_encode($arr);// converts php associative array to json format
file_put_contents($file, $json);
echo "successfull";

all arrays saved onto json text file on one Line,

[{"name":"Video 0","comment":"3RtYLZaUUdU"},{"name":"Video 1","comment":"QrIGoya6BcE"},{"name":"Video 2","comment":"KQbr2OGydJU"},{"name":"Video 3","comment":"bad movie, hate that sh*t."},{"name":"Video 3","comment":"REMOVE THIS MOVE"},{"name":"Video 3","comment":"nooooooooooooooo"},{"name":"Video 3","comment":"BAD movie"}]
