如何从单选按钮获取多个值，然后将它们分配到单个变量并在页面上显示？

// A major problem is once a user selects a radiobutton and hits submit the value, it sends an array. I would like to place those individual queries(route_no, to_city, from_city, price) on the nextpage.php page in a table next to their table headers or next to the tags. I cant do this because, confirm value sends all queries as a single string/array. How can I fix this please help me.enter image description here

use explode function to form a array separated by , .

使用explode函数形成一个由...分隔的数组。

     <?php

       $str = "4,sydney,canberra,120.00";
        print_r (explode(",",$str)); 

      ?>

   out put 

         Array
       (
          [0] => 4
          [1] => sydney
          [2] => canberra
          [3] => 120.00
         )

Yes explode can work like so, in nextpage.php

是的爆炸可以这样工作,在nextpage.php

<!DOCTYPE html>
<head>
<style>
td{    
    padding-top: 10px;
    padding-right: 10px;
    padding-bottom: 10px;
    padding-left: 10px;
}

</style>
<?php
  $details = explode(",", $_GET['Confirm']);
?>
</head>
<body>
<h1>Booking Details</h1>
<table>
  <tr>
   <th>Flight No.</th>
   <td><?=$details[0]?></td>
  </tr>
  <tr>
   <th>to_city</th>
   <td><?=$details[1]?></td>
  </tr>
  <tr>
   <th>from_city</th>
   <td><?=$details[2]?></td>
  </tr>
  <tr>
  <tr>
   <th>Price</th>
   <td><?=$details[3]?></td>
  </tr>    
</table>
</body>
</html>
