Route::get('/test', function () { return view('test'); }); Here is the result: Notice that any URL that does not have a specific entry in routes/web.php renders a “404 not complex conditional structures. 19 We also have @switch to show different things based on the result of a variable. Then we have shortcuts for common operations, convenient to use: @isset shows $dogs = Dog::all(); return view('dogs', ['dogs' => $dogs]); })->name('dogs'); Here’s the result: 36 8.

'PhotoController'); The Laravel service container is used to resolve all Laravel controllers. As a result, you are able to type-hint any dependencies your controller may need in its constructor: result set, it is recommended that you query the database and create a paginator manually. Sometimes you "deleted" models will not be included in query results. To force soft deleted models to appear in a result set, use the withTrashed method on the query: $users = User::withTrashed()->where('account_id'

want to fire: Firing an event: $responses = Event::fire('loaded'); Notice that we assigned the result of the fire method to a variable. This method will return an array containing the responses of all are defined in UPPERCASE or CamelCase in the table. Therefore, under the default attributes, query result object variables would only be accessible in lowercase. An example of the MySQL system settings querying your database simple. Here's an overview: Running a SELECT query and returning the first result: $user = DB::first('select * from users where id = 1'); Running a SELECT query and getting the
