如何从表单和make和数组中获取数据

I am just making a railway reservation project to my college therefor I have to get passenger details and make a 2d array and send it to another page to show the summary but I just don't know how to do that.

my code is

<?php
    include('connection.php');
    session_start();
    $train_number = $_GET['train_number'];
    $train_name = $_GET['train_name'];
    $coachid = $_GET['coachid'];
    $date = $_SESSION['date'];
    $day = $_SESSION['day'];
    $coachtype = $_SESSION['coachtype'];
    $useremail = $_SESSION['useremail'];
    if($_SERVER['REQUEST_METHOD']='POST')
    {
        if(!empty($_POST['proceed']))
        {
            $i = 1;
            while($i<7)
            {
                "What to write here";
            }
        }
    }
?>

    Here is an example of how to use 2D Arrays in PHP

    $cars = array
  (
  array("Volvo",22,18),
  array("BMW",15,13),
  array("Saab",5,2),
  array("Land Rover",17,15)
  );

    Now to access the data, you must specify the row and column:

    <?php
echo $cars[0][0].": In stock: ".$cars[0][1].", sold: ".$cars[0][2].".<br>";
echo $cars[1][0].": In stock: ".$cars[1][1].", sold: ".$cars[1][2].".<br>";
echo $cars[2][0].": In stock: ".$cars[2][1].", sold: ".$cars[2][2].".<br>";
echo $cars[3][0].": In stock: ".$cars[3][1].", sold: ".$cars[3][2].".<br>";
?>

    In this case:

    array("Volvo",22,18)

    That is a single row (0) and it has three columns (Volvo at row=0 column=0, 22 at row=0 colum=1, etc)

    I took the example from here: https://www.w3schools.com/php/php_arrays_multi.asp

    Let me know if this helps.
