What is Laravel?

• Laravel is an open-source PHP framework.
• Laravel is the most popular PHP Framework.
• Uses a MVC design pattern.
• Intended for the development of web applications keeping things clean and organized.
• Relational database access.
• Laravel has a “syntactic sugar” orientation.

MVC (Model View Controller)

Model: The central component of the pattern. It is the application’s dynamic data structure, independent of the user interface. It directly manages the data, logic, and rules of the application.

View: Any Representation of information such as a chart, diagram or table. In other words, the user interface.

Controller: Accepts input and converts it to commands for the model or view.

Composer

Composer is PHP package manager.

It is used to install Laravel as well as packages used inside a laravel app.

$composer global require laravel/installer
$laravel new webapp

Artisan

• Artisan is Laravel’s command line interface.
• Create Controller, Model, View, Migration and more.
• Run migrations
• Run scheduled tasks

Eloquent ORM (Object Relational Mapper)

The way you interact with the database without writing complex SQL queries.

For Ex: Let’s say you have post table and you want to retrieve all post

$posts= Post::gets();

If you want to apply the filter, need only active posts:

$activePosts=Post::where('active',true);

Blade syntax and templating

• Write once, use forever.
• Do not rewrite code every time you need a new page.
• Complied into plain PHP and cached.
• Views can extend layouts.
