change URL variables

[abscons]

Hi out there,
I have an url that looks like this: http://host/file?var=value.
I am trying to replace the "value" part in my url and assign it to a
link on my page. I tried to parse the url but can only get the part
before the ? not included.

Is there any way to do so?

Thx.

Yes. What do you have so far? Have you looked at $_SERVER[QUERY_STRING]
and $_SERVER[REQUEST_URI]?

I tried the REQUEST_URI but didn't work. I'll look at your link and
update when I go back to my project. Thx.

// this will replace (and/or add) parameters to the query string
$new_url = get_self_link(array('var'=>'new_value'));
// may seem like a lot of code, but I use these 2 funcs all the time.

function get_self_link($new_get_vars=array(),$full_url=fals e)
{
$string = '';
$get_vars = $_GET;
foreach ( $new_get_vars as $k=>$v )
$get_vars[$k] = $v;
$protocol = ( isset($_SERVER['HTTPS']) &&
$_SERVER['HTTPS']=='on' ) ? 'https' : 'http';
$current_url = $protocol.'://'.$_SERVER['HTTP_HOST'].
$_SERVER['REQUEST_URI'];

$query = get_query_string($get_vars);

$string = $protocol.'://'.$_SERVER['HTTP_HOST'];
$string .= $url_parts['path'].$query;

Yes. What do you have so far? Have you looked at $_SERVER[QUERY_STRING]
and $_SERVER[REQUEST_URI]?

This is the error I get when using REQUEST_URI: Notice: Undefined
index: REQUEST_URI

It needs to be:

$_SERVER['REQUEST_URI']

Note the quotes - this is an index in the $_SERVER array.

My exact call are:
$url = $_SERVER['REQUEST_URI'];
echo "URI: ".$url."<br/>";

and still: Notice: Undefined index: REQUEST_URI in index.php on line
21

Well, it should work, if your server is passing it on to PHP. Which
server are you using?

What does phpinfo() show? It should show REQUEST_URI.
