《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 '
{$pages['description']}{$story['headline']} |
";
/*db_connect函数功能*/ function db_connect() { $handle = new mysqli('localhost', 'content', 'password', 'content'); if (!$handle) { return false; } return $handle; } 回复内容:执行index.php文件时出现的问题,数据库已经建立。 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 '
