Why no [fragment] in parse_url($_SER VER['PHP_SELF'])?

[deko]

I'm trying to identify which named anchor is currently being viewed on a
page. Although the address bar of my browser shows #whatever appended to
the end of the url, I can't seem to find it in a variable.

My efforts below return no value for ANYTHING except [path]. Am I missing
something?

$url = parse_url($_SER VER['PHP_SELF']);

$scheme = ($url[scheme]);
$host = ($url[host]);
$port = ($url[port]);
$user = ($url[user]);
$pass = ($url[pass]);
$path = ($url[path]);
$anchor = ($url[fragment]);

echo $scheme." = scheme<br>";
echo $host." = host<br>";
echo $port." = port<br>";
echo $user." = user<br>";
echo $pass." = pass<br>";
echo $path." = path<br>";
echo $anchor." = anchor<br>";

10-4. That's what I am discovering. The goal here is to do different
things based on what section of the page is being viewed. Here's an
interesti ng article about using id's instead of names in anchors:
http://www.netmechanic.com/news/vol7/html_no6.htm

I've looked into Javascript a bit - but the question remains: how to
identify what anchor is currently beig viewed? If I can't do it in
PHP how
to do it in Javascript?
try this:

<script language="javas cript">
var a = (window.locatio n.href.split('# ')) ;
document.wri te(a[1])
</script>

thanks for the question!

of course, this doesn't strictly tell you which anchor is currently
being viewed, only which anchor was requested.

as far as i can see there is no window or document property
correspondi ng to the idea of 'last requested anchor' or 'live anchor' or
whatever.

But using deko's idea of using ids (eg <a id="foo" name="foo"></a>) you can
now do:

<script language="javas cript">
var a = (window.locatio n.href.split('# ')) ;
document.getEle mentById(a). <-- other stuff here
</script>

You could use it to alter the style or content of the element or surrounding
element.

the split() method returns an array, so you'd need:

<script language="javas cript">
var a = (window.locatio n.href.split('# ')[1]) ;
document.getEle mentById(a). <-- other stuff here
</script>

Thanks for the replies. I also heard that I could parse location.hash,
which will return anything from the hash (#) onwards in the current URI.
Does that sound like a better idea - or is it 6 of one, half dozen of the
other?

How about something like this:

function anchorname(n) {
var a=(window.locat ion.hash);
if (document.getEl ementById(a)=n) {anchorname=tru e}
}

Here's how I would code my link in the nav list:

<a href="test.php# test01"
onClick="anchor name('test01',' #currentlink')" >test01</a>

What I'm trying to do is apply css id #currentlink to the link if that's
where the user has navigated to. So I figure the function can test for a
given anchor name, and then somehow apply a style element if the function
returns true.

it sounds better to me!
