This article mainly introduces the relevant information of PHP Dependency Injection (DI) and Inversion of Control (IoC), which has certain reference value. Interested friends can refer to the first discussion of Dependency Injection and Inversion of Control. It's the same thing, it's a design pattern. This design pattern is used to reduce the coupling between programs. I studied it a bit and saw that there is no relevant article on the TP official website, so I wrote this humble article to introduce this design pattern. I hope I can contribute something to the TP community. First of all, don’t go into the definition of this design pattern, otherwise you will definitely be confused. The author is deeply affected by this. I have read many articles on Baidu, all of which are described from a theoretical perspective and are full of a lot of unfamiliar vocabulary. Either it is described in java code, which is also awkward. Anyway, I finally have some clarity. Let’s describe the concept of dependency injection from the perspective of PHP. Suppose we have a class here, which requires a database connection. According to the most primitive method, we may write this class like this: class example { private

2. Details of how to create objects in Java
##Introduction: Java developers create many objects every day, but they usually use dependency injection to manage the system. For example, Spring creates objects. However, there are many ways to create objects: use the New keyword, Use the newInstance method of the Class class, use the newInstance method of the Constructor class, use the Clone method, and use deserialization.

Detailed analysis of dependency injection sample code in JavaScript
##Introduction: The world of computer programming is actually a process of constantly abstracting simple parts and organizing these abstractions. JavaScript is no exception. When we use JavaScript to write applications, do we all use code written by others, such as some famous open source libraries or frameworks. As our project grows, more and more modules we need to rely on become more and more important. At this time, how to effectively organize these modules has become a very important issue. Dependency injection solves the problem of how to effectively organize code dependent modules. You may have heard the term "dependency injection" in some frameworks or libraries, such as the famous former...

PHP Inversion of Control (IOC) and Detailed explanation of dependency injection (DI) example code Introduction: In other words, if we need to modify Class B or Class C in the future development process, once it involves renaming the function, changing the number of function parameters, or even adjusting the entire class structure, we will also have to modify Class A Make corresponding adjustments, and the independence of class A is lost. This is very inconvenient during the development process. This is what we call "one thing affects the whole body." If the two classes are written separately by two people, conflicts often arise. It was at this time that it came into being. . . 7. PHP Inversion of Control and Dependency Injection ##Introduction: PHP Control Inversion and Dependency Injection 8.

To protect the application from session-related XSS attacks, the following measures are required: 1. Set the HttpOnly and Secure flags to protect the session cookies. 2. Export codes for all user inputs. 3. Implement content security policy (CSP) to limit script sources. Through these policies, session-related XSS attacks can be effectively protected and user data can be ensured.

Methods to optimize PHP session performance include: 1. Delay session start, 2. Use database to store sessions, 3. Compress session data, 4. Manage session life cycle, and 5. Implement session sharing. These strategies can significantly improve the efficiency of applications in high concurrency environments.

In PHP, you can use the session_name() function to configure the session name. The specific steps are as follows: 1. Use the session_name() function to set the session name, such as session_name("my_session"). 2. After setting the session name, call session_start() to start the session. Configuring session names can avoid session data conflicts between multiple applications and enhance security, but pay attention to the uniqueness, security, length and setting timing of session names.

The session ID should be regenerated regularly at login, before sensitive operations, and every 30 minutes. 1. Regenerate the session ID when logging in to prevent session fixed attacks. 2. Regenerate before sensitive operations to improve safety. 3. Regular regeneration reduces long-term utilization risks, but the user experience needs to be weighed.

Setting session cookie parameters in PHP can be achieved through the session_set_cookie_params() function. 1) Use this function to set parameters, such as expiration time, path, domain name, security flag, etc.; 2) Call session_start() to make the parameters take effect; 3) Dynamically adjust parameters according to needs, such as user login status; 4) Pay attention to setting secure and httponly flags to improve security.

The main purpose of using sessions in PHP is to maintain the status of the user between different pages. 1) The session is started through the session_start() function, creating a unique session ID and storing it in the user cookie. 2) Session data is saved on the server, allowing data to be passed between different requests, such as login status and shopping cart content.

How to share a session between subdomains? Implemented by setting session cookies for common domain names. 1. Set the domain of the session cookie to .example.com on the server side. 2. Choose the appropriate session storage method, such as memory, database or distributed cache. 3. Pass the session ID through cookies, and the server retrieves and updates the session data based on the ID.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
