use Illuminate\Validation\ValidationException; use Illuminate\Support\Facades\Validator; $data = [ 'email' => 'invalid-email', ]; $validator = Validator::make($data, [ 'email' => 'required|email', ]); try { $validator->validate(); } catch (ValidationException $e) { $errors = $e->validator->errors(); echo $errors->first('email'); // Output: The email must be a valid email address. }In this example, we are using the Laravel Validation package to validate an email address. We define a set of validation rules for the email field using the `Validator::make()` method. The `required` rule ensures that the field is not empty, while the `email` rule ensures that the field contains a valid email address. We then call the `validate()` method on the validator object to perform the validation. If there are any errors, a `ValidationException` is thrown. We can then access the validation errors using the `$e->validator->errors()` method, and output the first error message using the `$errors->first()` method. Overall, using Validator errors in PHP is a crucial step in ensuring that user-submitted data is valid and secure. The Laravel Validation package provides an easy-to-use and flexible way to handle these errors.
