How To Match Password & Confirm Password In laravel ??

What are you trying to do with the confirmed password? It is intended to be a validation mechanism only, not persisted.

$request->validate([
    // ... other stuff
    'password' => 'required|confirmed'
]);

Just set it up in the request validation as 'confirmed'

https://laravel.com/docs/5.6/validation#rule-confirmed

$this->validate($request, [
    'name' => 'required|min:3|max:50',
    'email' => 'email',
    'password' => 'required|confirmed|min:6',
]);

Now the validation will check if there is a field called password_confirmation and that it has the same value as the password field

beacuse $this use so how to data can save??

You realize Jeffrey has free tutorials and videos on the stuff correct. Yes some are paid but many are free.

@Bestmomo GitHub page has free complete laravel tutorial applications look it up.

The notion of password confirmation is not to save two hashed versions of the user's password in the database; instead, it is to ensure that the user knows what they have entered - by making them repeat the same password. You ensure this by validating that the password_confirmation field matches the password field - using the confirmed validation rule as both @lostdreamer_nl and I have described above.

Just use the validation and persist the hashed password whenever validation passes!
