What is the significance of using $_POST instead of HTTP_POST_VARS in PHP scripts?

Using $_POST instead of HTTP_POST_VARS in PHP scripts is significant because HTTP_POST_VARS is deprecated in newer versions of PHP. It is recommended to use $_POST as it is a superglobal variable that contains data sent to the script using the HTTP POST method. This ensures compatibility with current and future versions of PHP.
