我的代码是

<?php

    $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";
            }

所以，告诉我如果只填充2或3个字段并且制作2d数组，我怎样才能获取数据。如果你想要任何其他信息，我会给你..

Answer 1

以下是如何在PHP中使用2D数组的示例

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

现在要访问数据，您必须指定行和列：

<?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>";
?>

在这种情况下：

array("Volvo",22,18)

这是一行（0），它有三列（Volvo at row = 0 column = 0,22 at row = 0 colum = 1，等等）

我从这里拿到了例子：https://www.w3schools.com/php/php_arrays_multi.asp
