php laravel

hello folks

today we gonna learn learn about "php laravel"

as you all know php  is a widely-used open source general-purpose

 scripting language that is especially suited for web development and

it  can be also embedded into HTML...

there are so many frameworks of PHP

• Laravel.
• Symfony.
• Zend Framework.
• CodeIgniter.
• CakePHP.
• FuelPHP.
• Yii 2.
• Phalcon.

today i am going to walk you through laravel

featureas of laravel-

1. Automatic pagination

The paginate method provided by Laravel automatically takes

 care of setting the proper limit and offset based

 on the current page being viewed by the user.

2. View composers

The view composer is one of the most important 

features of Laravel which makes sure that the controllers

 load a bunch of data from models for views which is not

 related to that method’s page content.

3. Routing system

Laravel provides the flexibility to its developers

 to choose which route is triggered on the application. 

Laravel routes are defined in the app/Http/routes.php file,

 which is automatically loaded by the Laravel framework.

 The most basic Laravel routes simply accept a

 URI and a Closure, providing a very simple and

 expressive method of defining routes.

 The Laravel developer just need to enter the name of the

 route and it will automatically insert the correct URI.

4. Unit testing

Laravel enables its web artisans to test their

 code in the best way possible. Using the Artisan 

command line utility, laravel developers

 can write their own multiple unit tests easily.

@@ okay now let me walk you through the

                                                         installation process of laravel@@

we have some some requirments for installation of laravel

it comes with latest version of php

PHP >= 7.1.3

• OpenSSL PHP Extension
• PDO PHP Extension
• Mbstring PHP Extension
• Tokenizer PHP Extension
• XML PHP Extension
• Ctype PHP Extension
• JSON PHP Extension
• BCMath PHP Extension

for installing laravel in your system , you first need to install composer 

what is composer ??

composer is  php dependancy manager

•   Composer  you can download and install composer by clicking this link

you can install laravel using composer

• open cmd ( terminal ) write composer and HIT Enter to

          make sure that composer is installed in your in your system

• use this command to download and install laravel

      composer global require laravel/installer

Make sure to place composer's system-wide vendor bin directory in 

your $PATH so the laravel executable can be located by your system.

 This directory exists in different locations based on your operating system;

 however, some common locations include:

• macOS: $HOME/.composer/vendor/bin
• GNU / Linux Distributions: $HOME/.config/composer/vendor/bin
• Windows: %USERPROFILE%\AppData\Roaming\Composer\vendor\bin

• Once installed, the laravel new command will create a fresh Laravel installation in the directory you specify. For instance, laravel new blog will create a directory named blogcontaining a fresh Laravel installation with all of Laravel's dependencies already installed:

  laravel new blog

• Via Composer Create-Project

  Alternatively, you may also install Laravel by issuing the Composer create-project command in your terminal:

  composer create-project --prefer-dist laravel/laravel blog

• Local Development Server

  If you have PHP installed locally and you would like to use PHP's built-in development server to serve your application, you may use the serve Artisan command. This command will start a development server at http://localhost:8000:

  php artisan serve

  More robust local development options are available via Homestead and Valet.

Configuration

Public Directory

After installing Laravel, you should configure your web server's document / web root to be the public directory. The index.php in this directory serves as the front controller for all HTTP requests entering your application.

Configuration Files

All of the configuration files for the Laravel framework are stored in the config directory. Each option is documented, so feel free to look through the files and get familiar with the options available to you.

Directory Permissions

After installing Laravel, you may need to configure some permissions. Directories within the storage and the bootstrap/cache directories should be writable by your web server or Laravel will not run. If you are using the Homestead virtual machine, these permissions should already be set.

Application Key

The next thing you should do after installing Laravel is set your application key to a random string. If you installed Laravel via Composer or the Laravel installer, this key has already been set for you by the php artisan key:generate command.

Typically, this string should be 32 characters long. The key can be set in the .env environment file. If you have not renamed the .env.example file to .env, you should do that now. If the application key is not set, your user sessions and other encrypted data will not be secure!

Additional Configuration

Laravel needs almost no other configuration out of the box. You are free to get started developing! However, you may wish to review the config/app.php file and its documentation. It contains several options such as timezone and locale that you may wish to change according to your application.

You may also want to configure a few additional components of Laravel, such as:

• Cache
• Database
• Session

• Web Server Configuration

  Pretty URLs

  Apache

  Laravel includes a public/.htaccess file that is used to provide URLs without the index.phpfront controller in the path. Before serving Laravel with Apache, be sure to enable the mod_rewrite module so the .htaccess file will be honored by the server.
  If the .htaccess file that ships with Laravel does not work with your Apache installation, try this alternative:

  Options +FollowSymLinks -Indexes
  RewriteEngine On
  
  RewriteCond %{HTTP:Authorization} .
  RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
  
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteRule ^ index.php [L]

  Nginx

  If you are using Nginx, the following directive in your site configuration will direct all requests to the index.php front controller:

  location / {
      try_files $uri $uri/ /index.php?$query_string;
  }

  When using Homestead or Valet, pretty URLs will be automatically configured.
