[RESOLVED] Displaying the current URL/page

[jennyp]

To insert the full URL of a current page (this is for a shopping cart "return URL"), I was using this:

<? echo "$SERVER_NAME$PHP_SELF" ?>

This worked fine on my old hosting server (PHP Version 4.1.2). Then I changed my hosting server (PHP Version 4.3.11) and suddenly it wouldn't work. But now I find this works:

<? echo 'http://www.'.$HTTP_SERVER_VARS["SERVER_NAME"].$PHP_SELF.$_SERVER['REQUEST_URI']; ?>

As a PHP newbie I suspect both are suspect.. Is there a way of doing this that I should get into the habit of using?

$SERVER['SERVER_NAME'].$SERVER['PHP_SELF'].$_SERVER['REQUEST_URI'] would be more consistent. It may have to do with [man]register_globals[/man] being turned off for security reasons.

Thanks - I'm using that "more consistent" code with no problems. (Yes - register_globals was turned off on the old server, while on the new one it's turned on.)
