thinkphp obtains database information
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.
