php已get方式获取参数，处理后如何返回值

a.php从别的地址(b.aspx)接收一个参数（get方式）
a.php处理以后返回一个0到本身页面,例如a.php?0
b.aspx就可以通过getresponse接收到这个返回的0

请问a.php里如何返回一个0给自己？

回复讨论(解决方案)

什么叫返回一个0到本身页面？

$id = $_GET['id'];
echo $id;

输出到本页面还是加在url上?

比如我这个页面就是a.php
b.aspx用get传过来一个参数
a.php接收并处理后，在自己a.php后面加一个参数0：a.php?0
b.aspx用getResponese获取到这个返回的0

我只想知道在b.php里怎么样返回这样一个0

b.aspx用下面语句发送一个get请求参数给a.php，并要获取a.php的返回值
httpRes = HttpWebRequest.Create(new Uri(a.php + strUrlParameter)).GetResponse();

请问在a.php里如何返回值

估计是　ajax 吧？不知是不是与你说的是一回事

和ajax没有关系

看的不是很懂。

b.aspx用下面语句发送一个get请求参数给a.php，并要获取a.php的返回值
httpRes = HttpWebRequest.Create(new Uri(a.php + strUrlParameter)).GetResponse();

请问在a.php里如何返回值
a.php里echo返回值即可

a.php里echo返回值即可

是要返回给b.aspx的

ajax技术可以实现，直接在a.php中返回一个值可以直接用echo "要返回的值"，这是页面a中echo不是输出信息到浏览器的意思，而是返回值到b的意思,b就可以获取到返回的值了
