add/combine json array to array in JSON file php

I have been trying to solve this problem for the better part of two days with no success. I am trying combine/add to a json array that is stored in a .json file on my server using php.

This is a short version of what I'm trying to combine.

box.json:

[{"date":"25.4.2013 10:40:10"},{"comment":"some text"},{"comment":"some more text"}]

posted json:

[{"date":"25.4.2013 10:45:15"},{"comment":"another quote"},{"comment":"quote"}]

This is what I need.

[{"date":"25.4.2013 10:40:10"},{"comment":"some text"},{"comment":"some more text"},
{"date":"25.4.2013 10:45:15"},{"comment":"another quote"},{"comment":"quote"}]

This is what I get. (an array inside an array)

[{"date":"25.4.2013 10:40:10"},{"comment":"some text"},{"comment":"some more text"},
[{"date":"25.4.2013 10:45:15"},{"comment":"another quote"},{"comment":"quote"}]]

This is my code:

<?php
$sentArray = $_POST['json'];
$boxArray = file_get_contents('ajax/box.json');
$sentdata = json_decode($sentArray);
$getdata = json_decode($boxArray);
$sentdata[] = $getdata;   /* I also tried array_push($sentdata, $getdata); */
$json = json_encode($sentdata);
$fsize = filesize('ajax/box.json');
if ($fsize <= 5000){
    if (json_encode($json) != null) { /* sanity check */
    $file = fopen('ajax/box.json' ,'w+');
    fwrite($file, $json);
    fclose($file);
}else{
    /*rest of code*/
}
?>

Please help my sanity is starting to come in to question.

$box = json_decode(file_get_contents('ajax/box.json'));
$posted = json_decode($_POST['json']);
$merge = array_merge ((array)$box,(array)$posted);

Casting (array) prevent error if $box or $posted become null or false, it will be an empty array

Instead of this:

$sentdata[] = $getdata;   /* I also tried array_push($sentdata, $getdata); */

Try:

$combinedData = array_merge($sentData, $getData);
$json = json_encode($combinedData);

By using array_merge you're combining the arrays into one instead of adding one array as a value into the other.

Note that I changed the name of your resulting data - try to avoid variables with the same name and different capitalization, it will make things much easier to understand (for you and for future developers supporting your code).

here is your problem

$sentdata[] = $getdata;

use foreach

foreach($getdata as $value)
    $sentdata[] = $value;

UPDATE: but i think you need this for $sentdata not $getdata

foreach($senttdata as $value)
    $getdata[] = $value;

then put $getdata to your file.
