Switch Link according to page...

[g-a-m-e-r-x]

I have the page -GaMeR X-
and was wondering if someone could help with the "Home" and "Forums" links
I would like a simple "If" code to determine if you are on index.php, or another page and display the correct link so if your at the home page it would shop the "Forums" link and if your on another page it would show "Home"

I have this:

<?php
$uri = $_SERVER['REQUEST_URL'];
if ($uri == "/") {
echo "You're on the homepage";
} else {
echo "You're on an internal page";
}

?>

without

<?php ?>

also dosent work

This returns an error in vbulletin

$uri = $_SERVER['REQUEST_URI'];

Vbulletin throws this error on save:

vBulletin Message
The following error occurred when attempting to evaluate this template:

Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in /home/gamerxin/public_html/forum/includes/adminfunctions_template.php(3929) : eval()'d code on line 27

This is likely caused by a malformed conditional statement. It is highly recommended that you fix this error before continuing, but you may continue as-is if you wish.

Thanks!
