[FIXED] Composer Require Differences

Issue

I am just starting to learn about Composer, the PHP package manager. What are the differences between installing a dependency between these three commands?

composer require doctrine/dbal

composer require doctrine/dbal:2.*

composer require doctrine/dbal:2.0.0

Solution

You will find the detailed answer here: https://getcomposer.org/doc/articles/versions.md

The first will try install any version of doctrine/dbal package.
Second will try install one of the versions 2.
Third will try install version 2.0.0
