What are the best practices for passing parameters securely in PHP links for data manipulation operations?

When passing parameters securely in PHP links for data manipulation operations, it is important to sanitize and validate the input to prevent SQL injection and other security vulnerabilities. One way to achieve this is by using PHP's built-in functions like htmlspecialchars() and filter_input(). Additionally, you can encrypt sensitive data before passing it in the URL to further enhance security. 

// Sanitize and validate input parameters before using them in data manipulation operations
$param1 = filter_input(INPUT_GET, 'param1', FILTER_SANITIZE_STRING);
$param2 = filter_input(INPUT_GET, 'param2', FILTER_SANITIZE_NUMBER_INT);

// Encrypt sensitive data before passing it in the URL
$encrypted_param = base64_encode(openssl_encrypt($param, 'AES-256-CBC', 'secret_key', 0, '16charIV'));
