如何在Laravel 5中处理PDOException

Question

I've modified Exceptions/Handler.php to:

    <?php namespace App\Exceptions;

use Exception;
use Illuminate\Foundation\Exceptions\Handler as ExceptionHandler;
use Illuminate\Database\Eloquent\ModelNotFoundException as ModelNotFoundException;
use Symfony\Component\HttpKernel\Exception\NotFoundHttpException;

class Handler extends ExceptionHandler {

    /**
     * A list of the exception types that should not be reported.
     *
     * @var array
     */
    protected $dontReport = [
    'Symfony\Component\HttpKernel\Exception\HttpException'
    ];

    /**
     * Report or log an exception.
     *
     * This is a great spot to send exceptions to Sentry, Bugsnag, etc.
     *
     * @param  \Exception  $e
     * @return void
     */
    public function report(Exception $e)
    {
        return parent::report($e);
    }

    /**
     * Render an exception into an HTTP response.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Exception  $e
     * @return \Illuminate\Http\Response
     */
    public function render($request, Exception $e)
    {

        if($e instanceof NotFoundHttpException)
        {
            return response()->view('errors/404');
        }

        elseif ($e instanceof ErrorException) {
            return response()->view('errors/404');
        }

        elseif ($e instanceof ModelNotFoundException) {
            return response()->view('error_log(message)ors/404');
        }

        elseif($e instanceof PDOException)
        {
            return Redirect::to('install.php');
        }

        elseif($e instanceof QueryException)
        {
            return Redirect::to('install.php');
        }

        else return response()->view('errors/error');


    }

trying to redirect to installation whenever application makes PDOException, but I'm just getting general error view (errors/error - from the last line of the code above).

Is there a way to cach specifically PDOException error?

I think I've found the solution:

just put

use PDOException;
