I cannot retrieve session value stored in first php page?

Question

I stored a value of id in first php page as,

<?php

  ...
 $_SESSION["UID"] = $row["JS_ID"];
...

?>

this is the 2nd page,

<?php

  ...
 session_start(); 
$uid=$_SESSION["UID"];
...

?>

when am passing it as value it works,,but when I'm running my project, it's saying error as, "Undefined index UID"..Is there any way to clear it out?

Do you have session_start() in your first page? If not, your session isn't established and your variable will be lost. — user1864610

Try these:

Page1.php:

<?php

...
session_start(); 
$_SESSION["UID"] = $row["JS_ID"];
...

?>

Page2.php:

<?php

...
session_start(); 
$uid=$_SESSION["UID"];
...

?>

First you need to remove the session start from second page and start the session on that first page with

session_start();

Because whenever you have started the session then only you can access the session variables.But You are starting the session on the second page.Which has no use.
