How to get database information in thinkphp

Add database connection information to the project configuration file Conf/config.php:

// 添加数据库配置信息
'DB_TYPE'   => 'mysql', // 数据库类型
'DB_HOST'   => 'localhost', // 服务器地址
'DB_NAME'   => 'thinkphp', // 数据库名
'DB_USER'   => 'root', // 用户名
'DB_PWD'    => '', // 密码
'DB_PORT'   => 3306, // 端口
'DB_PREFIX' => 'think_', // 数据库表前缀

The main configuration items are the database server address hostname, database name database, database username username, database password password, and a table prefix prefix. After configuration, you can use tp5 query statements to query the database.

Or:

'DB_DSN' => 'mysql://root:密码@localhost:3306/thinkphp'

Modify the controller

Lib/Action/IndexAction.class.php

class IndexAction extends Action {
    public function index(){
        $Data = M('tinyphp'); // 实例化Data数据模型,这行的tinyphp为数据表后缀名称
        $this->data = $Data->select();
        $this->display();
    }
}

Modify the template to allow data output

Tpl/Index/index.html

<html>
 <head>
   <title>Select Data</title>
 </head>
 <body>
    <volist name="data" id="vo">
    {$vo.id}--{$vo.data}<br/>
    </volist>
 </body>
</html>

The volist tag is the tag used by the built-in template engine to output the data set.

{$vo.id} and {$vo.data} are used similarly to Smarty. They are fields used to output data. Here, it means outputting the values ​​of the id and data fields of the think_data table.
