How to show 404 page if route not found in laravel?

@dana 

To show a 404 page if a route is not found in Laravel, you can follow these steps:

1. Open the app/Exceptions/Handler.php file.
2. Locate the render method in the class.
3. Inside the render method, add the following code snippet:

1
2
3

if ($exception instanceof SymfonyComponentHttpKernelExceptionNotFoundHttpException) {
    return response()->view('errors.404', [], 404);
}

This code checks if the exception is an instance of NotFoundHttpException class, which occurs when a route is not found. If it is, it returns a view named errors.404 with a 404 status code.

1. Create a 404.blade.php file in the resources/views/errors/ directory. This file will contain the content of your 404 page.
2. Customize the content of the 404.blade.php file to match your application's design and requirements.

Now, whenever a route is not found, Laravel will automatically display the 404.blade.php view, showing a 404 page to the user.
