**Implementing Validation and Filtering for Form Inputs** In this topic, we will explore the importance of form validation and filtering in Zend Framework (Laminas). We will cover the different techniques and patterns used to validate and filter form inputs, and provide examples of how to implement them in a real-world scenario. **Why Validation is Important** Validation is a critical step in the web development process. It ensures that user input meets the expected format and requirements, reducing the risk of security vulnerabilities, data corruption, and unexpected behavior. In Zend Framework, validation is achieved through the use of validators and filters. **Types of Validators and Filters** There are two types of validators and filters used in Zend Framework: 1. **Validators**: These ensure that input data meets specific criteria, such as email validation or phone number validation. Zend Framework provides several built-in validators, including `Zend\Validator`, `Zend\Validator\AbstractValidator`, and `Zend_Wildcard`. 2. **Filters**: These modify input data, such as converting data types or removing unnecessary characters. Zend Framework provides several built-in filters, including `Zend Filter`, `Zend خارج]); The below code is from Zend Framework (Laminas): ```php use Zend\Filter\StripTags; use Zend\Formlement; ```
