I am trying to make my navigation to change color when selected. the class for selected is "current"

so I wrote this:

<ul class="<?php if(myfullpath() == "http://www.domain.com/first.php" || "http://www.domain.com/second.php"){echo "current";} else echo " "; ?>">

so if the url in the address bar is not first.php or second.php it should return false and echo " ", but for some odd reason this is returning true and posting class="current"> even if the url is posting http://www.domain.com/fourth.php.

JUST FYI here is the myfullpath function:

function myfullpath() { $s = empty($_SERVER["HTTPS"]) ? '' : ($_SERVER["HTTPS"] == "on") ? "s" : ""; $protocol = strleft(strtolower($_SERVER["SERVER_PROTOCOL"]), "/").$s; $port = ($_SERVER["SERVER_PORT"] == "80") ? "" : (":".$_SERVER["SERVER_PORT"]); return $protocol."://".$_SERVER['SERVER_NAME'].$port.$_SERVER['REQUEST_URI']; } function strleft($s1, $s2) { return substr($s1, 0, strpos($s1, $s2)); }


thanks for your help.
