+The PHPMonitor is a small PHP script with has to be pre-prended to all other PHP scripts of a website. This can be done either manually (unreliable) or by configuring the php.ini file of a server appropriatly (not always possible). The script relies on a cookie for the user identification to be available thorugh the [http://httpd.apache.org/docs/2.2/mod/mod_usertrack.html Apache module mod_usertrack].

+   * Requires the apache modules mod_usertrack to provide
+   * a cookie for user identification.

+  $log_name = "usage.log";
+  $cookie_name = "swe_informatik_uni-goettingen_de";
+
+  $postkeys = "";
+
+  while (list($key, $value) = each($_POST)) {
+    $postkeys = $postkeys." ".$key;
+  }
+  if( $_SERVER['HTTP_REFERER']=='' ) {

+  } else {
+    $referer = $_SERVER['HTTP_REFERER'];
+  }
+
+  $cookieVal = $_COOKIE[$cookie_name];
+  if($cookieVal==0) {
+    $apacheHeader = apache_response_headers();
+    $explodeResult1 = explode(';',$apacheHeader['Set-Cookie']);
+    $explodeResult2 = explode('=',$explodeResult1[0]);
+    $cookieVal = $explodeResult2[1];
+  }
+
