探索专为 PHP 编程语言生态系统设计的开源依赖管理器和库安装工具。
Composer is a command-line dependency management tool for PHP that automates the process of resolving, downloading, and installing external code libraries. It functions by evaluating version constraints defined in a project's configuration file to calculate a compatible dependency tree, ensuring that applications maintain consistent behavior across different development and production environments. The tool utilizes a structured manifest file as the single source of truth for project requirements and generates a deterministic lock file to record the exact version and hash of every installed d
Composer is the standard PHP dependency manager that handles composer.json manifests, dependency resolution, PSR‑4 autoloading, Packagist integration, lock files, a CLI, and plugin support—exactly the tool you need for managing PHP library dependencies.
