header( "Location: temp.php? user = $user" );

the variable is getting passed and is shown on the url of another page.

But i dont know how to use these var user in that page. Please help.

Answer 1

if the 'other page' is in PHP, you only need to:

$user=$_GET['user'];

EDIT: If you are not sure if you will receive 'user' and want to avoid error messages you should do:

if(isset($_GET['user'])){
    $user=$_GET['user'];
}else{
    //user was not passed, so print a error or just exit(0);
}
