How to Use Google Adsense With Drupal

<?php
// Puts some Google ads, but not on the search page or admin pages

// Get the request_uri to check whether you are on a search page
$uri = $_SERVER['REQUEST_URI'];

// check to see if the visitor is logged in
global $user;

if (!$user->uid) {  // only show ads to people who aren't logged in
  if (!strstr($uri, '/search/')) {  // make sure we are not on a Drupal search results page
   echo '
     // insert your adsense JavaScript code here
   ';
  } else {
   // if we are on a search results page, then insert alternate content
  }
}
?>
