Why is it recommended to use $_POST or $_GET instead of $_REQUEST in PHP code for better security and clarity?

Using $_POST or $_GET instead of $_REQUEST in PHP code is recommended for better security and clarity because it allows you to explicitly specify where the data is coming from. This helps prevent security vulnerabilities such as CSRF attacks. Additionally, using $_POST or $_GET improves code clarity by making it clear to other developers where the data is expected to be coming from.
