What is the composer package?
composer package refers to packaged code, that is, components, which are used to solve a certain problem in actual projects. For example, if you want to output a beautiful piece of data and get rid of the var_dump and print_r functions, then we can use the component var-dumper component; if we want to write logs, we can use monolog. These components have been developed by PHP developers. When we have such a scenario in the project, we can use them directly.

Why use components?
To sum it up in one sentence: Others have already built wheels, why don’t we use them? We don't need to reimplement the functions that have already been implemented. We should spend more time on the long-term goals of the project.
Characteristics of components
When we use PHP components, we must first determine whether the component is what we need, and whether some functions are not rigorous, like Buying vegetables at the wet market can be both good and bad. Such good components basically have these characteristics:
Single function
A component has a single function and can solve a problem very well. Just like we usually write methods in projects, a method only does one thing.
Small
There is not much code in the PHP component because it is produced only to solve a certain problem.
Cooperation
PHP components can cooperate well with each other. PHP components can cooperate with each other to solve more complex problems. Moreover, the components will be placed in their own namespace, so when we introduce them, they will not conflict with other components.
Good test
The PHP component is very convenient to test because of its small size.
Complete documentation
The documentation of the PHP component should be complete, allowing developers to quickly understand the installation and use of this component.

Composer: An Introduction to the PHP Dependency ManagerApr 21, 2025 am 12:02 AMComposer is a dependency management tool for PHP, which is used to manage libraries and packages required by projects. 1) It defines dependencies through composer.json file, 2) installs and updates using command line tools, 3) automates the dependency management process, improves development efficiency, 4) supports advanced functions such as dynamically adding dependencies and automatic loading, 5) Ensures consistency of the team environment through composer.lock file.
The Purpose of Composer: Managing Dependencies EfficientlyApr 20, 2025 am 12:04 AMComposer is a dependency management tool for PHP, and manages project dependencies through composer.json and composer.lock files. 1. Create the composer.json file and run the composerinstall installation dependency. 2. Use composerrequire to add new dependencies. 3. Configure autoload to implement automatic loading of classes. 4. Use composerdiagnose to check the health status of the project. 5. Optimize dependency management: specify the package name update, use composerdump-autoload-o to optimize the autoloader, use composerinstall--no-d in the production environment
Composer and AI: New Possibilities in PHP DevelopmentApr 19, 2025 am 12:03 AMThe combination of AI and Composer can improve PHP development efficiency and security. Specifically reflected in: 1. Dependency analysis and optimization: AI can predict dependencies and reduce conflicts. 2. Automated security checks: AI can identify security vulnerabilities, and it is recommended to update them. 3. Code generation and optimization: AI can automatically generate and optimize related code.

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),
