The difference between composer update and composer global update

Question

What is the difference between composer updateand composer global updatein yii2?

Answer 1

This has nothing to do with Yii directly.

Composer allows you to install dependencies globally or for each project (by default).

https://getcomposer.org/doc/03-cli.md#global

It's just a helper for managing a project stored in a central location where CLI tools or Composer plugins that you want to have everywhere can be stored.
