The difference between thinkphp and m method

The difference between ThinkPHP and M method

ThinkPHP is a lightweight PHP development framework that provides a wealth of functions and tools to easily and quickly develop high-quality Web applications. In the development process of ThinkPHP, the M method of the model layer is often used. So what are the differences between the M method and ThinkPHP's functions? Let me introduce it to you in detail below.

1. ThinkPHP

ThinkPHP is an excellent PHP development framework. Its main features are simplicity, efficiency, security, ease of use, flexibility, etc. The framework provides a complete MVC development model for rapid development, a special design for easy expansion and configuration, excellent documentation and support community, and powerful caching mechanism and data validation.

2. M method

M method is a model layer database operation method in ThinkPHP. Its main function is to operate the data in the database. Its syntax is:

$model->M($sql, $bind = [], $master = false, $class = false)

Among them, $sql is the SQL statement to be executed, $bind is the bound parameter, [] if there is none, $master is whether to operate as the main library, and $class is the name of the instance object class used.

3. The difference between M method and ThinkPHP

1. Development framework and model layer operation

ThinkPHP is a complete development framework that provides a wealth of The functions and tools include the model layer, view layer and control layer in the MVC architecture. The M method is just a data operation method in the model layer. It is an encapsulation of executing SQL statements on the database, and is different from the function of the framework.

2. Database connection method

ThinkPHP adopts a database abstraction layer and supports a variety of database connection methods. It can use PDO, MySQLi and native MySQL, etc., and can be flexibly carried out. Configure and adjust. The M method cannot choose the database connection method to use. The default database connection is used, which may not be supported by databases with different application scenarios and requirements.

3. Variable Binding

SQL statement binding variables in ThinkPHP can effectively prevent SQL injection attacks and improve program security. The M method cannot use variable binding. The bound parameters must be directly spliced ​​into the SQL statement, which can easily cause security issues.

4. How to execute SQL statements

ThinkPHP uses PDO or mysqli driver to execute SQL statements. After setting the relevant configuration, it can achieve certain performance optimization and security guarantee. Suitable for medium to large applications. The M method uses native MySQL to execute SQL statements, which has certain bottlenecks in the processing of large amounts of data and the operating efficiency of complex data structures.

To sum up, the M method is a database operation method in ThinkPHP. It is simple, convenient and very helpful for basic operations such as addition, deletion, modification and query of data. However, when developing more complex applications, it is also necessary to take into account the complete functions and security of the framework and configure and adjust it to achieve efficient and safe application development.
