In this tutorial I'm gonna show how you can validate user phone number using Laravel Validation Request. As we know usually we write the validation request in Controller. So Let's define a controller where we will show the validation rule.

Controller:

public function saveUser(Request $request){
        $this->validate($request,[
            'name' => 'required|max:120',
            'email' => 'required|email|unique:users',
            //'phone' => 'required|numeric|size:11'
            'phone' => 'required|regex:/(01)[0-9]{9}/'
            ]);

        $user = new User();
        $user->name=  $request->Input(['name']);
        $user->email=  $request->Input(['email']);
        $user->phone=  $request->Input(['phone']);
        $user->save();
       return redirect('success');     
    }
