Composer is a tool for dependency management in PHP. It allows you to declare the dependent libraries your project needs and it will

install them in your project for you.

Is it a new concept?

Is it a new concept? Nope.

Nope.

Ruby Package Manager

Nope.

But, what about PEAR?

• You have to install it in all the system

• You can´t see the source code

• Don´t allow different repository sources

• Don´t allow different repository sources

• Composer is compatible with PEAR, :)

Installing Composer (locally)

mkdir myprojectname

mkdir myprojectname

cd myprojectname

mkdir myprojectname

cd myprojectname

curl -s https://getcomposer.org/installer | php

mkdir myprojectname

cd myprojectname

curl -s https://getcomposer.org/installer | php

Done!
