Why is it recommended to use $_POST["ID"] instead of $ID in PHP scripts?

Using $_POST["ID"] is recommended over $ID in PHP scripts because it helps prevent security vulnerabilities such as SQL injection attacks. When using $_POST["ID"], the value is sanitized and validated before being used, reducing the risk of malicious code injection. It also helps improve code readability and maintainability by clearly indicating that the value is coming from a POST request. 

$ID = $_POST["ID"];
// Use $ID in your code
