《php和mysql web开发（原书第三版）》中创建CMS系统例子关于mysql的出错问题？

执行index.php文件时出现的问题，数据库已经建立。
错误提示:

Warning: mysqli::mysqli() [mysqli.mysqli]: (HY000/2003): Can't connect to MySQL server on 'localhost' (10061) in D:\apmxe\htdocs\28\db_fns.php on line 5

Warning: mysqli::query() [mysqli.query]: Couldn't fetch mysqli in D:\apmxe\htdocs\28\index.php on line 8

Fatal error: Call to a member function fetch_assoc() on a non-object in D:\apmxe\htdocs\28\index.php on line 12

开发环境:Apm express

请问这些问题如何解决呢？

补充:index.php连接数据库部分代码

$handle = db_connect();

  $pages_sql = 'select * from pages order by code';
  $pages_result = $handle->query($pages_sql);

  echo '

'; while ($pages = $pages_result->fetch_assoc()) { $story_sql = "select * from stories where page = '{$pages['code']}' and published is not null order by published desc"; $story_result = $handle->query($story_sql); if ($story_result->num_rows) { $story = $story_result->fetch_assoc(); echo "

{$pages['description']}

{$story['headline']}

Read more {$pages['code']} ...

";

/*db_connect函数功能*/
function db_connect()
{
   $handle = new mysqli('localhost', 'content', 'password', 'content'); 
   if (!$handle)
   {
     return false;
   }
   return $handle;
}
