very simple php question

[Anon]

If someone goes to

http://domain.com, how can I detect the query string to see what it is.

Basically I want to redirect the user to
http://www.domain.com, but ONLY IF its http://domain.com

if ($querystring != "www") {
header("Location: $querystring.'www'");
}

Also, I want to use the same code for each page, But I want the header know its location without having me to specify it each time, eg.

if i'm at http://domain.com/wherever.html it will take me to http://www.domain.com/wherever.html

thanks!

Hi,

Can you tell me what's the advantage of it?!! Only in Italy you can hear something like that, because they're not capable to setup correctly a server.

Why do you need that for?!!

I use that which you are describing, this is my code.

<?

if ($HTTP_HOST == 'domain.com') {
Header ("Location: http://www.domain.com$PHP_SELF");
die;
}

elseif ($HTTP_HOST == 'www.domain.com') {
?>

Your html, text...whatever.

<?
}
?>

Nothing fancy, but it works.

cant you just:

<?php
if(strstr($QUERY_STRING,"www.")) {
echo "<META HTTP-EQUIV="Refresh" Content = "0; URL=haha.shtml">
";
}
else {
echo "<META HTTP-EQUIV="Refresh" Content = "0; URL=whatever.shtml">
";
}
?>

actually replace that query string with http host
