What's wrong with just putting the url parameters in the link that

I have a footer that I include on every page and would like it to
adapt to whatever situation it finds itself in. Is your suggestion,
to do the following for the existing example:
echo "<a href='index.php?name=".$_GET['name']."&this=".
$_GET['this']."&lang=en'>Flip</a>";
Also, don't just output the values sent to the server, as that's an
attack waiting to happen.
Are you referring to echoing the SCRIPT_NAME and QUERY STRING values
into the href attribute?
I would add the parameter you want to $_GET ($_GET['lang']='en') and
use http_build_query on $_GET if you really want to include the whole
query string in the call:
$_GET['lang']='en';
echo '<a href="index.php?'.http_build_query($_GET).'">Flip</a>";

Woops, just realized a problem with this. If the values in $_GET are
URL encode, http_build_query will encode them again, so you have to
decode them first:
foreach($_GET as $k => $v) $qs[$k] = URLDecode($v);
$qs['lang'] = 'en';
echo '<a href="index.php?'.http_build_query($qa).'">Flip</a>';

I think you may have misunderstood. The problem is holding onto the
existing GET variables in the URL while manipulating or adding one of
them... and doing it dynamically no matter what the existing
parameters are.
My partciular problem scenario is this:
directions.php?mode=DRIVING&lat=45.514516&long=-73.611056&zip=H4N+2W2&lang=en
I would like the user to be able to switch between two languages via
the $_GET['lang'] var.

Your example is just as ugly as mine and in my editor is actually
worse because the SERVER vars aren't highlighted. Thanks anyways.

Hi Tamara,
Thanks for the tips. Do you see any advantage of this method over
using a small POST form besides the styling problems I'll run into
trying to make the submit button look like an achor?

The main advantage I see is that you're application doesn't have to
become bi-modal, with looking for variables on both the query string
and in the post data, then deciding which to use.

Hello there,
I have to make chat for website that has around 10 000 users (small

So, if you have time fill free to write you experience in this field,

Please consider the environment before printing this email.
I did that for a site for my buddy... i tried a few different ways, and
the current way seems to work decently... but i've been thinking about
altering it...
what i did for that one, is it inserts into a database what the person
wrote, then on eth other side, it pulls every x seconds from the db, and
using ajax adds to the<div>. it is a pain in the ass, but yeah, it
works. I also had a flag for "typing" indicator.
i am sure there are many different ways to do this, but posting to a db,
and pulling from the db seemed to be the logical way to do it when i did
that... my buddies old way of doing it, is at http://radiokaos.com
it just posts to the db, and then refreshed the iframe every 20 seconds
or something.
I use an Openfire server with the Smack client. Its really simple, well
documented and works really well.
Kind regards
Warren

Yep, Openfire is a jabber/xmpp server. There are however many other
alternatives.

That's all well and good, but the argument being used is a
generalization which at best is wrong. I don't care what you use,
but FUD doesn't help anything.
Cheers,

I disagree and what I said is not FUD.
If we took the time to *not* generalize, then we would be up to our
collective butts in evaluations of everything, while getting nothing
accomplished.
Generalization is a way to navigate the massive amounts of data we
are bombarded with each day. Do I want to spend/waste time evaluating
all templates to the nth degree? I think not.
Instead, I research ideas and see if they meet with my way of doing
things. If they do, then I incorporate them into my method -- if not,
then I pass.
I have changed my methods many times to accommodate new technologies
and new ways of doing things, but that does not mean that I always
incorporate everything that comes along. Templates are one of those
things that do not fit in my way of doing things and I do not need to
investigate all template systems to arrive at that conclusion. As
such, there is nothing wrong with my evaluation method for it works
for me.
I think the key quote here is "your way". Others will certainly have
different mileage (as has already been expressed), thus your
generalization still rings false. It's only a generalization for you
and others of like mind... which is terribly partisan :)
Cheers,
Rob.
And, in this case, "your way" is to disagree with "my way". :-)
In the end, we all have our methods of navigating information. If we
didn't we wouldn't be as far along as we are.
Cheers,
tedd

AFAIK variable variables can only reference actual variables--not array
subscripts or other non-variable syntax elements such as "->" or "::".
eval() can do this because it parses the code as PHP. Variable variables
take the *variable name* contained in the variable and look it up in the
current scope. This is a variable name:
ini_array
This is not:
ini_array['agis_core']['adapter']
I think you can use references here to do what you need. Warning: I only
tested the basics of this in the interpreter without running this exact
code.
public function explode_ini()
{
$ini_array = array();
foreach($this->ini_array as $heading => $key_vals)
{
foreach ($key_vals as $k => $v)
{
$path = &$ini_array[$heading];
$subsection = explode('.', $k);
foreach ($subsection as $ss)
$path = &$path[$ss];
$path = $v;
unset($path);
}
}
$this->ini_array = $ini_array;
}
