Tell you in an easy-to-understand way what composer does

The following is the tutorial column of composer to introduce to you what composer does. I hope it will be helpful to friends who need it!

#composer is a PHP dependency management tool.

Imagine not having to rely on management tools to manage projects:

If a project is developed by myself, I know exactly what libraries need to be introduced.

At this time, a new colleague has been added to the project to develop together. You tell him what library to introduce. At this time, you may encounter inconsistent library versions and inconsistent storage locations, and it is inconvenient to introduce dependent libraries (it is inconvenient to search, and you need to Downloading one by one on different websites, etc.) and other issues.

If the project continues to increase manpower, the project needs to be propagated, and the above problems will be repeatedly encountered when introducing dependent libraries.

After using the dependency management tool, everyone can solve the problem by using a unified dependency description method and introduction method to manage dependencies.

You no longer have to worry about project dependencies when spreading projects.
