Are there any recommended PHP form generators that are known to work effectively and securely for handling form submissions on websites?

When handling form submissions on websites, it is important to ensure that the form data is processed securely to prevent vulnerabilities such as SQL injection and cross-site scripting attacks. One way to achieve this is by using a reputable PHP form generator that has built-in security features to sanitize and validate user input. One recommended PHP form generator that is known for its effectiveness and security is the "PHP Form Builder" library. This library provides a simple and intuitive way to create and process forms with built-in validation and security measures.

```php
// Example code using PHP Form Builder library
require 'form-builder/form-builder.php';

$form = new FormBuilder();

$form->add('text', 'name', 'Name')->required();
$form->add('email', 'email', 'Email')->required()->email();
$form->add('textarea', 'message', 'Message')->required();

if ($form->submitted() && $form->validate()) {
    // Process form data securely
    $name = $form->getValue('name');
    $email = $form->getValue('email');
    $message = $form->getValue('message');

    // Perform necessary actions with the form data
    // For example, save to a database or send an email
}
```

This code snippet demonstrates how to use the PHP Form Builder library to create a form with input fields for name, email, and message. The library handles form validation and sanitization, making it a secure option for handling form submissions on websites.
