I have learned about the use session from you guys but when I am trying to use it in the following code,it is not working as I need. My code is trying to save a variable value in session array but I am not getting the value that I have saved in another php file. I have saved a value in the upload.php like this
Now I am accessing this value in another page just like this
But $u seems have no value. Why ? can someone explain it?
