Don't insert the same data multiple times into an array.

Here is a short code demonstrating what you are doing
--- example.php ---
<?PHP
for($i = 0; $i < 3; $i++) { // this replaces the foreach in the original
code
$MyObj[] = array("same each time", "this from round $i");
var_dump($MyObj);
}

--- eof ---

You can see how the array grows each iteration of the loop.

Some tips:
Separate display and logic into two files, one with only the logic and
one with only showing the resulting data, this makes it far cleaner and
simpler to update the design of the page without affecting the logic.

Do not have variable with the same name but different case, it makes
your code far more difficult to follow and more mistakes can sneak in

Validate input data, always go with whitelisting of what is allowed to
be in a input, this way you always know the data is safe to use. Regular expression can make this simpler.

Always calculate the total, do not trust that from a post or else
customers gets all the items for free. Also item prices should always be fetched from the stored price list, not from a post valu

Just that we are converting from php to php/json.

Further, the foreach is due to a line that is coming is from
a previous session being passed on.

Store data that you don't want to be manipulated but you need no the
next page in the session, as this data can't be manipulated by the user
and you don't need to revalidate the data on each page.

Using

Can you please reduce such questions this to the relevant part?

$myObj = [];
if (isset($_POST["submit"])){
(array_push($myObj,[

[...]

Why do you use array_push()? You can just build an array by assigning
values to it:

$myObj['key'] = $value;

[...]

'bill_first_name' =>[$_POST['bill_first_name']],

Why do you put an array here?

[$_POST['bill_first_name']] will resolve to a single element array:

'bill_first_name' => [ 'value' ];

Is this really what you want?

[...]

Just wonder how to supress repeats.

By using correct arrays and not that confusing mixture of values, empty
arrays and single element arrays.

The issue ain't related to the conversion, it's you logic that is flawed.

Further, the foreach is due to a line that is coming is from
a previous session being passed on.

But it's your foreach loop that makes you to have duplicates in your
example in the same way as in the small example file. Take some time and
think about what happens in each iteration, when you know what "$MyObj[]
=" means, then you can make the proper changes in your own code.

I would also think you could simplify the whole thing for example a lot
of the data is static, just set that data once not each time in a
foreach loop and also as Arno already pointed out, don't add a single
value as an array, you just make things more complex than they need to be.

Remember to not use input type="hidden" for information a user already
have posted to you, those goes into the session, the only thing would be
an identifier that is unique for this transaction. Prices you should
never take from post values, only the amount of items, for if you start
trust the posted values, I will be able to buy everything you have for 0
bucks.

I would also think you could simplify the whole thing for example a lot
of the data is static, just set that data once not each time in a
foreach loop and also as Arno already pointed out, don't add a single
value as an array, you just make things more complex than they need to be.

Remember to not use input type="hidden" for information a user already
have posted to you, those goes into the session, the only thing would be
an identifier that is unique for this transaction. Prices you should
never take from post values, only the amount of items, for if you start
trust the posted values, I will be able to buy everything you have for 0 bucks.
