  BETTER THAN THEREST? • Authentication • Routing • Sessions • Packages (Called Bundles in L3) • Command-line utility (Artisan) • Eloquent ORM • Migrations • Unit-Testing • Well tested, over 900 tests on core Use what makes sense for your project!

  REQUIREMENTS • PHP >=5.3.7 • MCrypt PHP Extension • PHP 5.5 may need PHP JSON Extension • Composer to manage dependencies
• 6.
  COMPOSER The problem thatComposer solves is this: a) You have a project that depends on a number of libraries. b) Some of those libraries depend on other libraries. c) You declare the things you depend on. d) Composer finds out which versions of which packages need to be installed, and installs them (meaning it downloads them into your project). https://packagist.org
