## Joomla_mysql: ####
## Normally in a helper class ####
<?php
/**
* Helper class for Hello World! module
*
* @package    Joomla.Tutorials
* @subpackage Modules
*/
class modHelloWorldHelper
{
function getHello( $userCount ){
        
        //$db = &JFactory::getDBO();
        $username="gigibri1_cross";
$password="zhengxin";
$database="gigibri1_dev";
        
        mysql_connect(localhost,$username,$password);
        @mysql_select_db($database) or die( "Unable to select database");

// get a list of all users
$query = 'SELECT * FROM jos_users';
//$db->setQuery($query);
$result = mysql_query($query);

$items = ($items = $db->loadObjectList())?$items:array();
// create a new array and fill it up with random users
$actualCount = count($items);
if ($actualCount < $userCount) {
    $userCount = $actualCount;
}
$items2 = array();
$rands = array_rand($items, $userCount);
foreach ($rands as $rand) {
     $items2[] = $items[$rand];
}
return $items2;

mysql_close();
return $result;
    }    
}

## Drupal_mysql: ####
## Normally in a module file ####
  $result_sell_price = db_fetch_object(db_query('SELECT i.sell_price FROM {image} i WHERE i.vid = %d', $node->vid));
  $node->sell_price=$result_sell_price->sell_price;
  
  
  
$result = db_query("SELECT i.image_size, f.filepath FROM {image} i INNER JOIN {files} f ON i.fid = f.fid WHERE i.nid = %d", $node->nid);
$node->images = array();
while ($file = db_fetch_object($result)) {
    $node->images[$file->image_size] = file_create_path($file->filepath);
}
