What are the advantages of using $_POST["ano"] over $ano in PHP form processing?
Using $_POST["ano"] is more secure than using $ano directly in PHP form processing because it ensures that the data is coming from a POST request and not from any other source. This helps prevent potential security vulnerabilities such as injection attacks. By using $_POST["ano"], you can also easily handle form data that is submitted via the POST method.
$ano = $_POST["ano"];
// Use $ano in your form processing code
