Question

I’m trying to get current page url. Here is the code:

$url = (!empty($_SERVER['HTTPS'])) ? "https://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'] : "http://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'];

It works fine. But I’m dealing with problem:

<a title="LT" href="<?php echo $url; ?>?lang=lt">LT</a>

When I press “LT” link once again, it gives me result:

http://127.0.0.1/index.php?lang=lt?lang=lt

How to avoid this?

$_SERVER['REQUEST_URI'] returns everything after the domain including the querystring (Well… not everything, since it can’t return fragments…)

If you want to use $_SERVER['REQUEST_URI'] then you could explode it like so:

$uri = explode('?', $_SERVER['REQUEST_URI']);
$uri = $uri[0];

And then use the $uri variable in place of $_SERVER['REQUEST_URI'] like this:

$url = (!empty($_SERVER['HTTPS'])) ? "https://".$_SERVER['SERVER_NAME'].$uri : "http://".$_SERVER['SERVER_NAME'].$uri;
