Some commonly used import settings in thinkphp

ThinkPHP is an open source PHP web application development framework with a mature MVC architecture and rich functional modules that can quickly develop high-quality web applications. When using ThinkPHP to develop applications, you often need to perform some import and setting operations. This article will introduce some common import settings of ThinkPHP.

1. Import files

When using the ThinkPHP framework, we need to introduce some class libraries within the framework into our program so that we can use the functions it provides. 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 way:

require_once 'framework/thinkphp.php';

This will Introduce the framework default file into the current file to facilitate us to use the functions of the framework.

2. Introduce the specified file

In some cases we do not need to introduce the entire framework into our program, we only need to introduce a specific file. 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 the purpose of customizing URLs. 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. In routing settings, we can also use regular expressions and other methods to define routing rules more flexibly.

3. Set up the database

When using ThinkPHP to develop a program, we need to connect to the database in order to perform related operations. 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

In ThinkPHP, we can use the template engine to dynamically render data into the web page. In ThinkPHP, we can use the following code 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 It can be modified according to the actual situation. The underscore __ROOT__ refers to the root directory of the project.

5. Conclusion

The above are some commonly used ThinkPHP introduction and setting operations. In the actual development process, we can also make more settings according to specific needs. Hope the above content can be helpful to you.
