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 '<table border="0" width="400">'; 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 = $story_result->fetch_assoc(); echo "<tr> <td> <h2>{$pages['description']}</h2> <p>{$story['headline']}</p> <p align='right' class='morelink'> <a href='page.php?page={$pages['code']}'> Read more {$pages['code']} ... </a> </p> </td> <td width='100'>";
/*db_connect函数功能*/ function db_connect() { $handle = new mysqli('localhost', 'content', 'password', 'content'); if (!$handle) { return false; } return $handle; }
mysqli链接的密码,账户都对吗????
首先确认你构造
mysqli
对象的时候,所有的参数都是正确的,这四个参数依次是数据库地址,用户名,密码,数据库名。其中数据库用户名和密码,你要确认下是否填写正确了。然后确认你的数据库是否启动了(很多人确实忘了)。在命令行下输入
看看是否能够连接上
