Can someone helpme, please?

I want to add (insert) another value or variable in the URL forum and URL Thread. Example:

Index.php File:

echo "<a href='/forumdisplay.php?fid=7'>Forum 1</a>" change to echo "<a href='/forumdisplay.php?fid=7&var1=X'>Forum 1</a>"
echo "<a href='/forumdisplay.php?fid=8'>Forum 2</a>" change to echo "<a href='/forumdisplay.php?fid=8&var1=X'>Forum 2</a>"


forumdisplay.php File:

echo "<a href='/showthread.php?tid=316'>Forum 1</a>" change to echo "<a href='/showthread.php?tid=316&var1=X'>Forum 1</a>"
echo "<a href='/showthread.php?tid=318'>Forum 2</a>" change to echo "<a href='/showthread.php?tid=318&var1=X'>Forum 2</a>"

I want to insert "var1=X". Where line in index.php and forumdisplay.php for insert this and how that's syntax?

Thanks Before
