<?php 

// ####################### SET PHP ENVIRONMENT ###########################
error_reporting(E_ALL & ~E_NOTICE); 

// #################### DEFINE IMPORTANT CONSTANTS #######################
define('NO_REGISTER_GLOBALS', 1); 
define('THIS_SCRIPT', 'imamac'); // change this depending on your filename 

// ################### PRE-CACHE TEMPLATES AND DATA ###################### 
// get special phrase groups 
$phrasegroups = array( 

); 

// get special data templates from the datastore 
$specialtemplates = array( 
     
); 

// pre-cache templates used by all actions 
$globaltemplates = array( 
    'imamac', 
); 

// pre-cache templates used by specific actions 
$actiontemplates = array( 

); 

// ######################### REQUIRE BACK-END ############################ 
require_once('./global.php'); 

// #######################################################################

 $res = mysql_query("SELECT username FROM user WHERE usergroupid = 2") or die("Error: ".mysql_error());
   $numRows = mysql_num_rows($res); // Here you get the number of rows returned
   echo "There are currently $numRows users";
$navbits = array(); 
$navbits[$parent] = 'Im a Mac'; 

$navbits = construct_navbits($navbits); 
eval('$navbar = "' . fetch_template('navbar') . '";'); 
eval('print_output("' . fetch_template('imamac') . '");');
