Help with HTTP_REFERER

[blanius]

I'm using $rfr=getenv("HTTP_REFERER"); to get page to check for page counter, but need some help "cleaning" it up so that

http://bretlanius.com/newindex.html and
http://bretlanius.com/newindex.html# and
http://www.bretlanius.com/newindex.html

are all the same record not seperate. I need this because onclick for some links open new windows and I use the #link to not go anywhere but you get different counts for each.

There are a multitude of ways to do this,

this is a simple example but not the most efficent

function strip_down($url)
{
   $x = $url;
   if(strpos($x,"http://") === 0)
     {
     	$x = substr($x,strlen("http://"));
     }

   if(strpos($x,"www.") === 0)
     {
     	$x = substr($x,strlen("www."));
     }

   if(strpos($x,".html") !== 0)
     {
     	$x = substr($x,strpos($x,".html")+5);
     }

}

Not checked the above and it's not the best code but it is simple and should give you a basic starter.

Regular expressions would probably be a better solution should you want to look up the manual.
