$_SESSION['id']=$i[id];?>

.jpg"/>

$i里有10条信息，
点击任何图片通过$_SESSION到B页面后打印出的都是10
怎么才能做到点击的哪一个图片，打印出哪一个图片的ID

回复讨论(解决方案)

你如果只是想获得图片ID，那你可以通过GET方法传递参数，而不是SESSION，SESSION是服务器端的，你在客户端点击图片，服务器端是无法知道你点哪个图片的，也无法通过你点击对象来改变SESSION，除非你传递了参数过去。
这样写吧
">

B页面：
echo $_GET['id'];

$_SESSION[$i[id]]=$i[id];?>

">
页面间的$_SESSION传输 .jpg"/>

B.php
session_start();
$id=$_GET['id'];
echo $_SESSION[$id];
