Problem with ajax using jquery when sending data to php

I am having a weird problem sending data to php using ajax with JQuery here is my code:

<?php
    $chkStates = $_POST['chkStatesObject'];
    $newChkStates = json_decode($_POST['newChkStates'], true); // True to convert the JSON result to an associative array.
    echo gettype($newChkStates);
    echo sizeof($newChkStates);
?>

<?php
    $chkStates = $_POST['chkStatesObject'];
    $newChkStates = json_decode($_POST['newChkStates'], true); // True to convert the JSON result to an associative array.
    echo gettype($newChkStates);
    echo sizeof($newChkStates);
?>

JavaScript

function ConfirmReservationOptions()
        {
            if(newChkStates.charAt(newChkStates.length - 1) == ",")
                newChkStates = '"{' + newChkStates.slice(0, -1) + '}"';
            // console.log(newChkStates);
            $.ajax({
                url: 'confirm_reservation_options.php',
                type: 'POST',
                async: true,
                data: {chkStatesObject: chkStatesObject, newChkStates: JSON.stringify(newChkStates)},
                success: function(response){
                    $("#reservationOptionsResults").html(response);
                },
            });
        }

function ConfirmReservationOptions()
        {
            if(newChkStates.charAt(newChkStates.length - 1) == ",")
                newChkStates = '"{' + newChkStates.slice(0, -1) + '}"';
            // console.log(newChkStates);
            $.ajax({
                url: 'confirm_reservation_options.php',
                type: 'POST',
                async: true,
                data: {chkStatesObject: chkStatesObject, newChkStates: JSON.stringify(newChkStates)},
                success: function(response){
                    $("#reservationOptionsResults").html(response);
                },
            });
        }

Solution:

Can you not edit this? You are converting it to a string here newChkStates = '"{' + newChkStates.slice(0, -1) + '}"';...

Here are the errors I am getting from the php

Alex•6mo ago

The error is refering to the php part where I used echo sizeof($newChkStates); I need it to be converted to associative array instead of a string.

Here is the value of newChkStates in the console when I console.loged it

Or maybe I am reading too far and the error happens earlier
