Chapter 5. Load and Resolve with Composer, an Evolutionary

Composer is not only a package manager, but also a dependency manager in PHP. In PHP, if you want to reuse an open source component, the standard way to do it is to use an open source package through Composer, as Composer has become a standard for making packages, installing packages, and auto-loading. Here, we have discussed a few new terms, such as package manager, dependency manager, and auto-loading. In this chapter, we will go into detail of what they are and what Composer provides for them.

The preceding paragraph explains what Composer mainly does, but Composer is more than that.

In this chapter, we will look at the following things:

  • Introduction to Composer
  • Installation
  • Usage of Composer
    • Composer as a package and dependency manager
    • Installing packages
      • How Composer works
