How to Implement Dependency Injection in PHP
Article Introduction：Implementing dependency injection (DI) in PHP can be done by manual injection or using DI containers. 1) Manual injection passes dependencies through constructors, such as the UserService class injecting Logger. 2) Use DI containers to automatically manage dependencies, such as the Container class to manage Logger and UserService. Implementing DI can improve code flexibility and testability, but you need to pay attention to traps such as overinjection and service locator anti-mode.

How to Build Your Own Dependency Injection Container
Article Introduction：This article discusses how to build a simple dependency injection container (DI container) PHP package. All code in the article, including PHPDoc annotations and unit tests (100% code coverage), has been uploaded to the GitHub repository and listed on Packagist.
Key points:
Building DI containers helps developers understand the basic principles of dependency injection and the working mechanism of containers.
DI containers have two main functions: "dependency injection" and "container". It needs to be able to instantiate and include services using constructor injection or setter injection methods.
Symfony dependency injection containers can be used as a reference for creating custom containers. It divides container configuration into parameters and services, allowing secure storage

How to execute SQL statement with parameters in PHPMyAdmin
Article Introduction：Execution of SQL statements with parameters in PHPMyAdmin can be achieved in three ways: 1) Splicing through SQL strings, although simple, it needs to prevent SQL injection; 2) Using PHP preprocessing statements, it is highly secure but requires writing code outside PHPMyAdmin; 3) Using user-defined variables, it directly operates in PHPMyAdmin but fails after the variable session ends.

What is dependency injection, and how do I use it in PHP?
Article Introduction：Dependency injection (DI) is a design pattern used to improve code flexibility and testability. 1. It reduces coupling by providing dependencies from the outside rather than internal creation; 2. In PHP, DI is usually implemented through constructors or setter methods; 3. Using DI can improve testability, flexibility and separate concerns; 4. Dependencies can be automatically resolved through containers during actual use; 5. However, DI can not be used in simple scripts or performance-sensitive scenarios.

How do I connect to a database using PHP (MySQLi, PDO)?
Article Introduction：To connect to a database, there are two ways to PHP: MySQLi and PDO. 1.MySQLi is simple and direct, suitable for projects that only use MySQL, supports process-oriented and object-oriented writing, and it is recommended to use object methods to obtain a clearer structure; 2.PDO is more flexible and supports multiple databases, suitable for projects that may migrate databases or require unified interfaces, has preprocessing statements to prevent SQL injection, and provides a unified error handling mechanism. Choosing MySQLi allows for a cleaner API and slightly higher performance, while choosing PDO allows for improved scalability and security. Both need to pay attention to correct configuration, error handling and connection closure.

is it necessary to use a php framework
Article Introduction：Whether or not the PHP framework is necessary depends on project requirements and development habits. For medium and large projects, using frameworks can improve code quality and save development time because frameworks provide standardized structures (such as MVC mode), built-in common functions (such as database operations, routing, authentication), enhanced security (such as anti-SQL injection), and integrated auxiliary tools (such as cache, queues). 1. The advantages of the framework include: standardizing code structure, improving maintenance, accelerating development speed, enhancing security, and integrating common functions. 2. The situation where the framework is not used is: small or one-time project, high-performance requirements scenarios, and basic skills practice during the learning stage. 3. Use the framework to pay attention to: learning costs are high, flexibility is limited, and performance overhead is present. It is recommended to choose appropriate based on the project size and personal ability.
