2. What is Composer
• “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.”

3. That’s mean?
• Scope is per project, not global
• Resolves dependencies
• Runs installation tasks

4. Why should we use it

• PEAR per global, not per project
• How can we get exactly same version for
other? (composer.lock)
