Hi everyone !
I am a newbie to this newsgroup. I would appreciate if someone can help
me to solve this problem.
OK, I am currently writing a webpage in PHP that will get RSS file(XML
file) (news feed) and parse it using PHP and display articles' link and
description. I want everytime a user click on one article's link, it
take the user to another page which was written by me (for example,
"display.php?aid=43232") (I don't want user to leave my website) and
pass the article ID to the URL string. Everything run fine at this
point but I got duplicate filename on the URL
("display.php?aid=43232&display.php="). I don't know how to fix this.
Here is the code.

========= Code for display.php =========
<?php
echo "<h1>Display news </h1>";
$id = $_GET["aid"];
$baseLink = "http://www.prweb.com/printer.php?prid=";
