What are common mistakes beginners make when implementing email address validation in PHP scripts?

Common mistakes beginners make when implementing email address validation in PHP scripts include not using the appropriate filter functions, not properly sanitizing user input, and not handling validation errors effectively. To solve this issue, beginners should use the filter_var function with the FILTER_VALIDATE_EMAIL flag to validate email addresses, sanitize user input using the filter_var function with the FILTER_SANITIZE_EMAIL flag, and handle validation errors by displaying appropriate error messages to the user. 

$email = $_POST['email'];

// Validate email address
if (filter_var($email, FILTER_VALIDATE_EMAIL)) {
    // Sanitize email address
    $sanitized_email = filter_var($email, FILTER_SANITIZE_EMAIL);
    // Process the sanitized email address
} else {
    echo "Invalid email address";
}
