PHP $globals and env vars

[Anon]

I am trying to find out how to tell what request a users has made when they connect to my site for the first time

say for example, a user types in http://www.some.com/xxx.php in their bowser window and then go -

or just the domain name.

Does anyone know what variables would contain the domain or host part and the requested file.

Some one mentioned HTTP_HOST and REQUESTED_URI but I can not get these to even return a value.

Any help greatly appreciated.

Mark.

$SERVER_NAME will show the domain name and $PHP_SELF will show the filename. ie.

http://www.some.com/xxx.php

<?
echo "$SERVER_NAME<br>\n";
echo "$PHP_SELF<br>\n";
?>

Is this what your looking for?

Thanks for that. thats part way there.

I am tring to get this to work

// code to create session_id here
$location = http://$SERVER_NAME$PHP_SELF/$sess_id
header ("location $location");

Where sess_id is md5 hash length 32.

It gives me 401 error.
I am testing this on a PC with omnihttp and MYSql lattest beta.

I have been tring alsorts of things

Is it supposed to look like this ?

http://www.one.com/test.php/aAD568wkd5294bd

or like this?

http://www.one.com/test.php?aAD568wkd5294bd

The top url will look for a dir named test.php wich is strange, that you would have a dir named exactly yhe same as every file in your dir. then after it has entered the temp.php dir it will look fr a file with the same name as your md5 hash, strange, but has aplications I guess.

if it is the second you are looking for you possibly may find it easier to do this.

http://$SERVER_NAME/$PHP_SELF?md5=$sess_id

you'll get

http://www.one.com/test.php?md5=aAD568wkd5294bd

What I an trying to achiev is a script that is included in every page. It will check the existance and validate a unique id 32 chars.
If the id is invalid,expired or none existant it shoud reload the main index2.php
this what I have so far .
I have had to use getttype incase some one type is xid= or xid becaus isset return true in those cases.

And if there is a fatal error i.e no mysql connection diverts to an errror page
My aim is no cookies and no client side script and no browser or server specific stuff. Also to keep the code php3 and 4 compat.

Here is what I have so far --

<?php
Include ("../libs/dbase.php"); // generic dbase connection.
Include ("../libs/session.php");
$SERVER_NAME = getenv("SERVER_NAME");
$dba = new session;
$xiderror = 0;

$fredtype = gettype($xid); // use this because isset return true for ?xid= and ?xid

$fredlength = strlen($xid);

if($fredtype == "NULL" || $fredlength <> 32)
{
$xid = 0;
$xiderror = 1;
}

If (!$xid == 0) // could and the stuff here
{
if (!ereg("^{[0-9a-z]{32}$",$xid))}
{
$xiderror = 1;
$xid =0;
}
else
{
if (!$session_ok = $dba->make_session($xid))
{
$xid=0;
$xiderror = 1;
}
}
}

If ($xiderror)
{
$dba->seshid=0;
if ($session_ok = $dba->make_session(0))
{
$session_id = $dba->seshid;
$xid = $session_id;
$destination = sprintf("http://%s/index2.php?xid=%s",$SERVER_NAME,$session_id);
//unset($dba);
Header("location: $destination");
exit;
}
Else
{
$destination = sprintf("http://%s/sorry.html",$SERVER_NAME);
Header("location: $destination");
exit;
}

}
else

$xid = $dba->seshid;

?>

Forgot to say what I could not fix in prev code.

If I play with the id it works,
But if I delete the id from the database it does not refresh the url with the new id in it.

Sorry.
