Are there any recommended resources or libraries for handling URL and email validation in PHP to simplify the process and reduce the risk of errors?

When handling URL and email validation in PHP, it's recommended to use established libraries or functions to simplify the process and reduce the risk of errors. Libraries like Symfony's Validator component or the filter_var() function in PHP can help ensure that URLs and email addresses are properly validated according to standard formats.

// Example using filter_var() for email validation
$email = "example@example.com";

if (filter_var($email, FILTER_VALIDATE_EMAIL)) {
    echo "Valid email address";
} else {
    echo "Invalid email address";
}
