我正在为我的大学做一个铁路预订项目我必须得到乘客的详细信息并制作一个二维阵列并将其发送到另一页以显示摘要但我不知道该怎么做。
<?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";
}
}
}
?>

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..
答案 0 :(得分: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
如果有帮助,请告诉我。
