Basic Operations with Artisan Tinker

Now that we have our shell up and running, let's play around with some basic operations:

>>> dd('Hello, World!');
=> string(13) "Hello, World!"

• Database queries: Execute database queries using Eloquent's fluent syntax.

>>> $users = App\Models\User::all();
=> Illuminate\Database\Eloquent\Collection {#3057 ▼
     #items: array:5 [▼
         0 => App\Models\User {#3061 ▶}
         1 => App\Models\User {#3062 ▶}
         ...
     ]
 }

Debugging with Artisan Tinker

One of the most significant benefits of using Artisan Tinker is its ability to help you debug issues in your application. Here are a few examples:

>>> dd($user->name);
=> string(10) "John Doe"

• Trace back issues: Step through your code using the debug_backtrace() function.

>>> debug_backtrace();
=> array:11 [▼
     #file => "/path/to/your/file.php"

     #function => "exampleFunction"
     ...
 ]
