How to solve the $ _ SESSION transmission between pages

$ _ SESSION transmission between pages $ _ SESSION ['id'] = $ I [id];? & Gt; & lt; a & nbsp; href = "B. php? & Lt ;? Php & nbsp; echo & nbsp; $ I ['id']? & Gt; "& gt; & lt; img & nbsp; src =" $ _ SESSION transmission between img pages

">
. Jpg "/>


$ I contains 10 messages,
Click any image and print it to the B page through $ _ SESSION.
How can I select the image to be clicked and print the ID of the image? session: ">
------ Solution --------------------
If you only want to GET the image ID, you can pass the parameter through the GET method, instead of the SESSION. The SESSION is on the server side. you click the image on the client side, the server cannot know which image you click or change the SESSION by clicking the object, unless you pass the parameter.
Write it like this.
Id = ">

Page B:
Echo $ _ GET ['id'];
------ Solution --------------------
$ _ SESSION [$ I [id] = $ I [id];?>

">
. Jpg "/>


B. php
Session_start ();
$ Id = $ _ GET ['id'];
Echo $ _ SESSION [$ id];
