What are the common ThinkPHP framework operations in PHP programming?

With the continuous development of Internet technology, PHP programming has become a widely used programming language. In PHP programming, the use of frameworks can facilitate developers to standardize code, facilitate maintenance, and develop efficiently. ThinkPHP is an excellent PHP framework that is widely popular in PHP programming. This article will introduce some common ThinkPHP framework operations.

1. Database operation

Database operation is an important operation in PHP programming. ThinkPHP provides developers with rich database query statements and operation methods. Among them, common database operation methods include CURD operations, join table queries, transaction processing, etc.

In the CURD operation, Create, Read, Update, and Delete correspond to the addition, reading, modification, and deletion of data respectively, and can realize basic operations of data. Join table query refers to data query between two or more tables. Joint query of data can be realized by writing SQL statements. In transaction processing, multiple SQL operations can be placed in the same transaction to achieve simultaneous submission or rollback of data.

2. Template engine operation

The template engine is one of the important tools in PHP programming, which can facilitate page display. ThinkPHP provides a tag-based template engine that can separate HTML and PHP code through different tags, reduce code coupling, and improve code readability.

In ThinkPHP, the template engine can realize customized page display by writing template files. By passing parameters to tags, calling controllers, calling methods, etc., data display and processing can be easily achieved.

3. Routing operation

Routing operation is an important step in PHP programming, which realizes the mapping relationship between URL and controller. In the routing operation, you can beautify the URL, reduce the complexity of the URL, and improve the user experience.

ThinkPHP’s routing operations can be performed through routing configuration files and annotations. Through the routing configuration file, the mapping relationship between URL and controller can be realized, including routing matching rules, modules, controllers and methods, etc. Through annotations, routing settings can be made directly on the controller method to easily achieve refined routing matching.

4. Form validation operation

Form validation is an important security operation in PHP programming. ThinkPHP provides a variety of form validation methods to ensure the correct format and security of the data. .

In ThinkPHP, form verification can be achieved by writing rule array verification, model verification, manual verification, etc. In rule array verification, you can write verification rules, error messages, verification scenarios and other rules to verify the form. In model validation, you can set validation rules through the model and perform data insertion and update operations directly.

In short, ThinkPHP, as a widely used PHP framework, plays an important role in PHP programming. This article introduces some common ThinkPHP framework operations, including database operations, template engine operations, routing operations, form validation operations, etc. I hope it will be helpful to PHP developers.
