change URL variables

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.

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'];
$url_parts = @parse_url($current_url);
$query = get_query_string($get_vars);
if ( $full_url )
$string = $protocol.'://'.$_SERVER['HTTP_HOST'];
$string .= $url_parts['path'].$query;
return $string;
}

/************************************************** **********/
// similar to http://www.php.net/function.http-build-query
// does not handle arrays
function get_query_string($attribs)
{
$query = '?';
foreach ( $attribs as $k=>$v )
{
if ( $v !== null && !is_array($v) )
{
$query .= $k;
$query .= '='.str_replace('%2F','/',urlencode($v));
$query .= '&';
}
}
$query = substr($query,0,-1);
$query = str_replace('&','&amp;',$query);
return $query;
}

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

server are you using?

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