HTTP global PHP variables

Is there a way to get a reference to the global arrays that contain HTTP request data like get, post, cookie, etc. ? For example:

$varName = getRequestReference()['varName'];

where getRequestReference() would return &$_GET, &$_POST...depending on the type of request that the user used to submit data in the script.

You can use $_REQUEST to either grab the $_POST, $_GET or $_COOKIE values

See the documentation for more details.

You could also create a custom function that either grabs $_POST or $_GET, depending which has the requested key:

function getRequest($key)
{
    if(!empty($_GET[$key]))
    {
        return $_GET[$name];
    }
    if(!empty($_POST[$key]))
    {
        return $_POST[$name];
    }

    return null;
}

$varValue = getRequest('varName');

This function will return the updated values (when you modify one of these global variables at run-time)
