What is the purpose of using the HTTP_POST_VARS array in PHP for form submission?

The HTTP_POST_VARS array in PHP was used in older versions to access form data submitted via the POST method. However, this array is deprecated and no longer recommended for use. Instead, you should use the $_POST superglobal array to access form data submitted via POST method.

// Using the $_POST superglobal array to access form data submitted via POST method
$value = $_POST['input_name'];
