Call to a member function httpUrl() on null when called inside a function?

[desbest]

When I use the following code I get an error.

<?php
function test(){
    return $page->httpUrl();
    // return $wire->page->httpUrl();
}
$test = test();
echo $test; 

I get this error.

Error:     Call to a member function httpUrl() on null

How do I fix it? How do I get the current page's url inside a function? The function is being stored on the same template file of the page being displayed.

There's something called function scope in PHP. In a hurry, please Google forums for more info. For now, use:

wire('page');
wire('pages');
wire('input');
// etc...
