PHP - Array For Loop Not Storing Values

Question

I created an empty array and want to store values from another array coming from a form. I am getting only the last value stored in the array, it is for some reason overlapping the values that need to be stored in a multidimensional array.

<?php 
$Vendor1 = [];
$Vendor2 = [];
    
$OrderCode = $_POST['OrderCode'];
$OrderType = $_POST['OrderType'];
$OrderAmount = $_POST['OrderAmount'];

for ($i=0; $i<count($OrderCode); $i++)
{
    
if ($OrderType[$i] == "V1")  { $Vendor1[] = array("OrderCode" => $OrderCode[$i], "OrderAmount" => $OrderAmount[$i], "OrderType" => $OrderType[$i]) ; }

if ($OrderType[$i] == "V2")  { $Cheetay[] = array("OrderCode" => $OrderCode[$i], "OrderAmount" => $OrderAmount[$i], "OrderType" => $OrderType[$i]) ; }
}


foreach($Vendor1 as $key => $value)
        {
        echo $key." - ".$value;
    }


?>

The Output I am getting is 0 - Array 1 - Array and so on ... not the actual values that should have been stored. Please help me to fix my mistake !
