-About Laravel Installation

For example, in a MAC environment, install Composer before installing Laravel, install Laravel by using Composer (note: Composer is a tool used in PHP to manage dependency (dependency) relationships. You can declare the dependent External tool library (libraries) in your project, and composer will help you install the dependent library files.

The way to install composer is simple, go to composer's official website, click the download option, and you can see there's a curl command

Copy this command to the Terminal (Command line tool), you can download a Composer.phar file here is recommended to download the composer after the command

  Mvcomposer.phar/usr/local/bin/composer  

Put this file into the Usr/local/bin directory and become a global directive for use when creating new directories later.

Using commands in the command-line tool after installing composer

  Composercreat-projectlaravel/laravellaravel5   

You can successfully install the Laravel

It is recommended to turn on the VPN before using the command

After successful installation, jump to laravel directory using the command CD laravel5/and use the artisan command

Phpartisanserve   

will return an HTTP address, browse the address, you can jump out of a built-in Web page, to this step, the entire installation process is over.

-2-laravel's basic workflow

(Note: The concept of routing/Controller/view will be described in detail in a later article)

Each time the laravel is used, it is first booted into a routes.php file, which in the./app/http directory, the first open can see three lines of code

Route::get ('/', function () {return  

These three lines of code define a route (you need to define a route before starting an HTTP program.) In the previous example, our business logic was implemented in the routing, which is no problem for simple Web sites or Web applications, and when we need to scale up, the program becomes complex, and layered business logic is more appropriate. At this time, we should use the controller)

Here the '/' refers to the root directory where the contents of the anonymous function are executed when the browser accesses the root directory

This time it is time to return to a view view, which is saved in the./resources/views Directory

The welcome here is a PHP file name, which represents a PHP

Now let's create a new controller in command line tool input command

  Phpartisanmake:controllerhellocontroller  

Back to the code editing interface, in the HTTP controllers directory can see the new controller, in the hellocontrollers can see the system automatically created a lot of methods, now we write this line of code in the index method

Return  

And go back to routes.php to write this line of code

Similarly, access to the root directory will appear laravel welcome interface

The new line of code in routes refers to finding the index method in Hellocontroller after the root directory is accessed, @ can be understood as the calling method

So, about Laravel and the basic usage process introduced here,
