What are the commonly used import settings in thinkphp?

1. Import files

In order to use the functions provided by the ThinkPHP framework, we need to introduce some class libraries within the framework into our program. In ThinkPHP, we can use the following two methods to import files.

1. Introducing the framework default file

The framework default file is stored in the framework directory. We can introduce it in the following ways:

require_once 'framework/thinkphp.php';

This will introduce the framework default file into the current file, making it easier for us to use the functions of the framework.

2. Introduce specified files

Sometimes we only need to introduce specific files without having to move the entire framework into our program. In ThinkPHP, we can use the following method to import:

require_once 'path/filename.php';

The path here refers to the path where the file we need to import is located, and filename is the file name, which needs to include the file extension.

2. Set routing

In ThinkPHP, we can define routing rules to send requests to specified controllers and operations to achieve custom URLs the goal of. In ThinkPHP, we can use the following code for routing settings:

'URL_ROUTER_ON'   => true, // 开启路由
'URL_ROUTE_RULES'=>array( //定义路由规则
    'user/:id'=>'user/show',
),

'user/:id'=>'user/show' here means that all /user/id requests will be sent to user control The device is in show operation. For routing settings, we can use other methods such as regular expressions to make it more flexible to set routing rules.

3. Set up the database

In order to perform related operations, we need to connect to the database to develop ThinkPHP programs. In ThinkPHP, we can use the following code for database settings:

'DB_TYPE'=> 'mysql', // 数据库类型
'DB_HOST'=> 'localhost', // 服务器地址
'DB_NAME'=>'test', // 数据库名
'DB_USER'=>'root', // 用户名
'DB_PWD'=>'123456', // 密码
'DB_PORT'=>'3306', // 端口
'DB_PREFIX'=>'think_', // 数据库表前缀

where DB_TYPE represents the database type, DB_HOST represents the server address, DB_NAME represents the database name, DB_USER represents the database user name, DB_PWD represents the database password, and DB_PORT represents Database port, DB_PREFIX represents the database table prefix. We can modify the above parameters according to the actual situation.

4. Set up the template engine

Using the template engine can dynamically render data into a web page in ThinkPHP. The following code can be used in ThinkPHP for template engine settings:

'TMPL_PARSE_STRING'=>array(
    '__PUBLIC__'=>__ROOT__.'/Public',
    '__JS__'=>__ROOT__.'/Public/js',
    '__CSS__'=>__ROOT__.'/Public/css',
    '__IMG__'=>__ROOT__.'/Public/img'
),

The __PUBLIC__, __JS__, __CSS__, __IMG__ here represent the public directory, JS directory, CSS directory and image directory used in the project, we can Modify according to actual situation. The underscore __ROOT__ refers to the root directory of the project.
