Hello artisan,

If you need to check database connection exists or not in Laravel then we can check the database connection using DB PDO and DB getDatabaseName(). Let's see the example code of check database connection in Laravel:

app/Http/Controllers/DemoController.php

namespace App\Http\Controllers;
  
use Illuminate\Http\Request;
use DB;
  
class DemoController extends Controller
{
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function index(Request $request)
    {
  
        if(DB::connection()->getDatabaseName())
        {
            $database = DB::connection()->getDatabaseName();
            dd("Connected successfully to database ".$database.".");
        }
  
    }
}

You can check another way like:

app/Http/Controllers/DemoController.php

namespace App\Http\Controllers;
    
use Illuminate\Http\Request;
use DB;
use Exception;
    
class DemoController extends Controller
{
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function index(Request $request)
    {
    
        try {
            DB::connection()->getPDO();
            $database = DB::connection()->getDatabaseName();
  
            dd("Connected successfully to database ".$database.".");
        } catch (Exception $e) {
            dd("None");
        }
    
    }
}
