Path in Laravel

App Path:
app_path() : get tihe full path of the app directory
base_path(): get the path to the root directory of the application
public_path(): get the full path of the publich directory
storage_path(): get the storage (app/storage) directory path
Migration
To create the migration, via the command line, in the root folder of your application, simply type:
php artisan migrate:make create_users_table ––create=users
This will automatically create a migrations file inside of yourapp/database/migrations folder. Let’s take a look at the newly created file.
To run the migration andcreate our user table, use the command line again and run:
php artisan migrate
Just like that, the command will use the up() function and bam! We have our users table with all the columns we wanted.
Reverting Migrations: Now if you wanted to rollback migrations, we could use php artisan migrate:rollback or php artisan migrate:reset.
Adding CSS Files:
{{ HTML::style(path-to-css-dir/file-name.css’)}}
{{ HTML::style(‘css/main.css’)}}
Working With Session:

<p class=”alert”>{{ Session::get(‘message’) }}</p>
@endif
