See the file() function. It works on http requests too, even though it's
grouped with filesystem functions.

To make a page that refreshes itself every 10 seconds, use a meta tag.
<META HTTP-EQUIV="Refresh" CONTENT="10; URL=>
The
previous tag will cause the page that you are on to refresh in 10
seconds
to .

To create a link to the previous page you can use the
getenv("HTTP_REFERER")
command and set it up as a
hyperlink. You might also want to put a IF condition on it so it won't get
displayed if the user has gone straight in to the page.

To display the current URL, I'd rather
use
$REQUEST_URI
or
$SERVER_NAME.$REQUEST_URI
This will
include the query-string.
Make a phpinfo() file to see all environment
variables.

To redirect your visitors without interference (no warning/explanation) you
should use
header("Location: );
If
you would first like to tell your visitors what is going to happen
('You'll be redirected in 5 secs') you should consider meta-tags or
JavaScript.

$HTTP_RAW_POST_DATA --
You'll usually access variables from forms
sent via POST method by just accessing the associated PHP global
variable.
However, if your POST data is not URI encoded (i.e.,
custom application that's not form-based) PHP won't parse the data into
nice variables for you. You will need to use $HTTP_RAW_POST_DATA to
access the raw data directly. (This should return a copy of the data given
to the PHP process on STDIN; note that you wan't be able to open STDIN and
read it yourself because PHP already did so itself.)

When using the $SERVER_NAME or other predefined variables within a function
BE SURE to use $GLOBALS["SERVER_NAME"] in its place =)

Please note, in previous message, Decode_Chunked_Message() function will
fail in some case (whitespace between chunk size and crlf)
To avoid
this :
modify line
$chunk_size=substr($message,$chunk_pos,$crlf_pos);
by
$chunk_size=chop(substr($message,$chunk_pos,$crlf_pos));
AND
$chunk_size=substr($message,$chunk_pos,$crlf_pos-$chunk_pos);
BY
$chunk_size=chop(substr($message,$chunk_pos,$crlf_pos-$chunk_pos));

Redirecting:
If you want the URL you are redirecting to with
header("Location: $url") to appear in the location bar in your
browser, you have to add a <CRLF> at the end of the string; ie
header("Location: blah.com\r\n") It'll still redirect without
the \r\n but for some reason the URL remains unchanged in the location
bar.

The last post must be related with an older version of some browser. I've
tried it with both IE 6.0 (which comes with XP) and Mozilla 1.1, both with
\r\n and without it, and in both cases the new URL shows up in the address
bar.
I do remember such a glitch with IE in the past however.

If you're wanting to perform an HTTP POST, I've written a small but useful
function to do so:

[Editor's Note:] This method uses JavaScript which requires the visitor's
browser to have javascript enabled [/Note]
Another way, to
redirect to an url without any notification or
message:
Print("window.location='$urlvar';");

I wanted to do an http redirect taking into account their current
uri:
ie. authentication failed - redirect to
login.php
$NewPage = 'login';
$NewURL = preg_replace(
"[\w+(?=\.php)]", $NewPage, $_SERVER[ "SCRIPT_URI" ]
);
header( "location: $NewURL\r\n" );
Hope this might
be useful for someone.
