Add a core wrapper function to retrieve $wp->request

[apedog]

Feature request: add a core wrapper function to retrieve global $wp->request.

Core should provide a function wp_get_uri_request() (or some other naming convention) to reliably get the uri request. And reduce reliance on globals/superglobals.

<?php
global $wp;
$url = $wp->request;

instead use:

<?php
$url = wp_get_uri_request();
