composer is a tool used in PHP to manage dependencies. You can declare the external libraries (libraries) you depend on in your project, and Composer will install these dependent library files for you.

The advantage of Composer is that you only need to provide a composer.json file to declare the third-party libraries that need to be used. A simple command All its dependencies can be installed. It is also convenient for project deployment and release, because you only need to provide a composer.json.
The current disadvantage is the lack of direct support for some static resources (such as js, css), which may be related to its positioning.
Of course, Composer is not only a dependency management tool, but also provides automatic loading support. This involves the PSR-0 specification of the php-fig organization. If you are interested, please visit its official website: PHP-FIG — PHP Framework Interop Group.
