Preventing adding link to another link - php

Question

Hello I'm currently working with php to generate a menu with a own build CMS system.
I'm making a dynamic link with : $url = $_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']."/";
Than I'm adding . $row_menu['page_link'] from the database. At first it works perfect:
as example =
$row_menu['page_link'] = page2;
$url . $row_menu['page_link'];
it will return as example : http://example.com/page2
But when I click again, it adds page2 again like : http://example.com/page2/page2
How do i prevent this?
Thanks in advance!

Answer 1

Because at first time your $_SERVER['REQUEST_URI'] will be like http://example.com but when the user click on the link then the value of $_SERVER['REQUEST_URI'] would become http://example.com/page2.That's why it is appending two times.
Instead you can use HTTP_REFERER like
$url = $_SERVER['HTTP_REFERER'].$row_menu['page_link'];
Considering that your $_SERVER['HTTP_REFERER'] will results http://example.com.Also you can try like
$protocol = 'http';
$url = $protocol .'//'. $_SERVER['HTTP_HOST'] .'/'. $row_menu['page_link'];

Answer 2

REQUEST_URI will give you whatever comes after example.com, so leave that out all together.
$url = $_SERVER['HTTP_HOST'] . "/" . $row_menu['page_link'];
You can find a full list of the $_SERVER references here.

Try this:
$requested_uri = $_SERVER['REQUESTED_URI'];
$host = $_SERVER['HTTP_HOST'];
$uri_segments = explode('/',$requested_uri);
$row_menu['page_link'] = 'page2';
if($row_menu['page_link'] == $uri_segments[sizeof($uri_segments)-1]) {
array_pop($uri_segments);
}
$uri = implode('/',$uri_segments);
$url = 'http://'.$host.'/'.$uri.'/'.$row_menu['page_link'];
echo $url;
