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.

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
|
1 |
$posts= Post::gets(); |
If you want to apply the filter, need only active posts:
|
1 |
$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.
