The Role of Email Validation in Yii
Before delving into the technical aspects, let's understand why email validation is crucial in Yii:
Data Accuracy: Email validation ensures that the email addresses collected through web forms are accurate and properly formatted.
User Experience: Validating email addresses in real-time provides users with instant feedback, enhancing their experience by preventing submission errors.
