PHP Display Telephone Number On Referrer

Posted on 16th Feb 2014 by admin

I have used the php below to show a different telephone number in the header of the site depending upon where the visitor comes from. The code below works but looses the original referrer information upon click of own site links, defaulting the telephone number back to the generic number.

Is there away to save it to the session, maybe the start session and save session is not done correct?

Thanks for any help

<?PHP
session_start();
if(!isset($_SESSION[’referrer’])){

$referer = strtolower($_SERVER["HTTP_REFERER"]);

if (strstr($referer,"site1"))
{
echo("<h1>Telephone Number1</h1>");
}
else if (strstr($referer,"site2"))
{
echo("<h1>Telephone Number2</h1>");
}
else if (strstr($referer,"site3"))
{
echo("<h1>Telephone Number3</h1>");
}
else if (strstr($referer,"site4"))
{
echo("<h1>Telephone Number4</h1>");
}
else
{
echo("<h1>Telephone Number5</h1>");
} $_SESSION[’referrer’] = $referrer; // store session data
}?>
