php - 无法将 php session 变量设置到另一个 php 页面

Question

我无法将一个页面上的 session 变量设置到另一个页面，我的代码如下。

首页

session_start();
header('Content-Type: application/json;charset=utf-8');

///mysql connections
while($row = mysql_fetch_array( $sthpre )){
// Print out the contents of each row into a table

$rows[] = $row; 
$_SESSION['id']=$row['id'];
print json_encode($row);

}//still i get null on the other page $_SESSION['id'] = 22;

第二页

session_start();
header('Content-Type: application/json;charset=utf-8');
$row['id']=$_SESSION['id'];
print json_encode($row);

Answer 1

尝试一下:

session_start();

session_regenerate();

header('Content-Type: application/json;charset=utf-8');

$row['id']=$_SESSION['id']; print json_encode($row);
