Are there any recommended PHP libraries or classes available for automating form validation tasks?

When building web forms, it's essential to validate user input to ensure data integrity and security. One way to automate form validation tasks in PHP is by using existing libraries or classes that provide easy-to-use validation rules and error handling. This can save time and effort in writing custom validation code for each form field. 

// Example using the Symfony Validator Component
use Symfony\Component\Validator\Validation;
use Symfony\Component\Validator\Constraints as Assert;

$validator = Validation::createValidator();

// Define validation rules for form fields
$constraints = new Assert\Collection([
    'name' => [
        new Assert\NotBlank(),
        new Assert\Length(['min' => 3, 'max' => 50]),
    ],
    'email' => [
        new Assert\NotBlank(),
        new Assert\Email(),
    ],
]);

// Validate form data
$errors = $validator->validate($_POST, $constraints);

if (count($errors) > 0) {
    // Handle validation errors
    foreach ($errors as $error) {
        echo $error->getMessage() . "<br>";
    }
} else {
    // Proceed with form processing
}
