Code Select Expand

<?php
require_once('include/config.inc.php');
header("Content-type: application/x-javascript");

$connect = mysqli_connect($CONFIG['dbserver'],$CONFIG['dbuser'],$CONFIG['dbpass'])
or die('Error connecting to the server');

$connect_db = mysqli_select_db($CONFIG['dbname'], $connect)
or die ('Error connecting to the database');

$resultado = mysqli_query("SELECT * FROM `cpg_albums` ORDER BY `cpg_albums`.`aid` DESC LIMIT 0 , 6", $connect)
or die('No albums found with this query');
                                        
echo 'document.write(\'';
if(mysqli_num_rows($resultado) == 0){
echo 'No albums created';
} else {
echo '<ul id="galbuns">';
while($row = mysqli_fetch_array($resultado)){
echo ' ';
$album_id = $row['aid'];
$subresult = mysqli_query("SELECT * FROM `cpg_pictures` where aid=$album_id order by pid DESC LIMIT 0, 6");

if(mysqli_num_rows($subresult) == 0){
$album_img = "http://siteurl.com./galeria/thumbs/thumb_nopic.png";
} else {
while($subrow = mysqli_fetch_array($subresult)){
$album_img = "http://siteurl.com./galeria/albums/".$subrow['filepath'].'thumb_'.$subrow['filename']  .$subrow['datebrowse'];
                                                                                
}
}

echo '<li><div class="galtitul"><a href="http://siteurl.com./galeria/thumbnails.php?album='.$album_id.' ">'.$row['title'].'</a></div></li>';

echo '';
}
}

echo '</ul>';
echo '\');';

?>

it reports "unable to connect to database"

Are you sure it reports exactly that message?
