What are some potential pitfalls of using a simple function like maxWordLength for design protection in PHP?

One potential pitfall of using a simple function like maxWordLength for design protection in PHP is that it may not provide sufficient security against more advanced attacks or vulnerabilities. To improve design protection, consider implementing additional security measures such as input validation, output encoding, and proper error handling. 

function maxWordLength($input, $max_length) {
    if (strlen($input) > $max_length) {
        return substr($input, 0, $max_length);
    }
    return $input;
}

// Example usage
$input = $_POST['input'];
$max_length = 50;
$filtered_input = maxWordLength($input, $max_length);
