Select all from table with Laravel and Eloquent

You simply call

Blog::all();

//example usage.
$posts = Blog::all();

$posts->each(function($post) // foreach($posts as $post) { }
{
    //do something
}

from anywhere in your application.

Reading the documentation will help a lot.

There are 3 ways that one can do that.

1 - Use all() or get();

$entireTable = TableModelName::all();

eg,

$posts = Post::get(); // both get and all  will work here

or

$posts = Post::all();

2 - Use the DB facade

Put this line before the class in the controller

use Illuminate\Support\Facades\DB; // this will import the DB facade into your controller class

Now in the class

$posts = DB::table('posts')->get(); // it will get the entire table

or a more dynamic way would be -

$postTable = (new Post())->getTable(); // This will get the table name
$posts = DB::table($postTable)->get();

The advantage of this way is that in case you ever change the table name, it would not return any error since it gets the table name dynamically from the Post model. Make sure to import Post model at the top like DB fadade.

3 - Use the DB facade with select

Put this line before the class in the controller

*Same import the DB facade like method 2*

Now in the controller

$posts = DB::select('SELECT * FROM posts');
