Laravel Installation

#Install Composer
Laravel utilizes Composer to manage its dependencies. First, download a copy of the composer.phar. Once you have the PHAR archive, you can either keep it in your local project directory or move to usr/local/bin to use it globally on your system. On Windows, you can use the Composer Windows installer.

#Install Laravel
Via Laravel Installer
First, download the Laravel installer using Composer.

Make sure to place the ~/.composer/vendor/bin directory in your PATH so the laravel executable is found when you run the laravel command in your terminal.

Once installed, the simple laravel new command will create a fresh Laravel installation in the directory you specify. For instance, laravel new blog would create a directory named blog containing a fresh Laravel installation with all dependencies installed. This method of installation is much faster than installing via Composer.

Via Composer Create-Project
You may also install Laravel by issuing the Composer create-project command in your terminal:

Via Download
Once Composer is installed, download the 4.2 version of the Laravel framework and extract its contents into a directory on your server. Next, in the root of your Laravel application, run the php composer.phar install (or composer install) command to install all of the framework's dependencies. This process requires Git to be installed on the server to successfully complete the installation.

If you want to update the Laravel framework, you may issue the php composer.phar update command.

Server Requirements
The Laravel framework has a few system requirements:

PHP >= 5.4
MCrypt PHP Extension
As of PHP 5.5, some OS distributions may require you to manually install the PHP JSON extension. When using Ubuntu, this can be done via apt-get install php5-json.
