[PHP] who is on the page?
Hi everybody, I've been looking for a script to determine who is on my page (people have to log in). So far, I've been using a script that updates the time in the database continuously as long as the person is on the page. That way, the script could determine whether the user is still online or not. However, this script has way too many queries and uses too much server resources. Is there anything else? I'm wondering if the connection_status() function would help in any way... thx, Olli -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] authentication problem
Hi again, My problem was about authentication without the default popup, but with a form that submits the credentials. I still didn't get it to work, so I'd like to know if anyone has ever done anything like that. I just can't get it to work right and I'd like to see a working script thx, Oliver -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

ok, here's the code:
the form submits the user name and password in the variables $user and $pw to
another site, which includes this:
if(isset($user) isset($pw)){
$user = ucwords(strtolower($user));
$PHP_AUTH_USER = $user;
$PHP_AUTH_PW = $pw;}
if(isset($PHP_AUTH_USER)){
$result = mysql_query(select * from _users where user = '$PHP_AUTH_USER');
$_user = mysql_fetch_array($result);}
if(!isset($PHP_AUTH_USER)) {
header('HTTP/1.0 401 Unauthorized');
echo('unauthorized');
exit;}
else{
$result = mysql_query(select * from _users where user = '$PHP_AUTH_USER') or
die('Error occured while connecting to database');
$rows = mysql_num_rows($result);
if($rows == 0){
header('HTTP/1.0 401 Unauthorized');
echoscriptwindow.location.href='../index.php?action=user_wrong'/script;

// authorized
}
else{

And this works fine for just this page. Whenever I click on a link to a page
which includes the same file though, it echoes 'unauthorized'...

Sounds like you're using sessions... perhaps register_globals is off in
your environment, so session variables are not registered? How do you set
the $user and $pw variables?
no, im not using sessions and register globals is on.
the variables user and pw are set by submitting a form (method=post). that's
where i expect the mistake to be. because as far as i know, the browser usually
saves the credentials, at least the user name after authenticating. but it just
doesn't seem to do so

Plain US-ASCII text may still be assumed in the absence of a MIME-Version or the presence of an syntactically invalid Content-Type header field, but the sender's intent might have been otherwise. 6.1. Content-Transfer-Encoding Syntax The Content-Transfer-Encoding field's value is a single token specifying the type of encoding, as enumerated below. Formally: encoding := Content-Transfer-Encoding : mechanism mechanism := 7bit / 8bit / binary / quoted-printable / base64 / ietf-token / x-token These values are not case sensitive -- Base64 and BASE64 and bAsE64 are all equivalent. An encoding type of 7BIT requires that the body is already in a 7bit mail-ready representation. This is the default value -- that is, Content-Transfer-Encoding: 7BIT is assumed if the Content-Transfer-Encoding header field is not present.

Hi,
i'm running a selfmade PHP-chat since one and a half year, currently version
3. Maybe we can share some ideas
The image-idea is interesting, but would take heavy bandwith i think.
My chat runs over a simple dsl-line with 256kbit upstream, there are up to
50 users at the same time (slow but okay). It's very good at 30 users, but
there is a whole community with galleries etc. on the same server.
What i know:
To avoid reloads, you must use a stream. That's the
flush()'n'sleep()-thing. This is my main-loop:
01 ini_set(max_execution_time, 0);
02 for(;;)
03 {
04 $newline = get_newline($last_row);// fetch a new line (out of an
database for example, returns time, alias, text as array, or false if no new
line is found)
05 if(is_array($newline))
06 {
07 $newtext = format($newline);// format line for output (text
bla could be (01:01) Alias: bla and /me bla could be Alias bla,
returns the string to be outputtet to the browser)
08 if($newtext AND $newtext != $oldtext) echo $newtext;// if it's
new text (avoids flooding), output the line!
09 $last_row = $newline[id];// next time fetch another id
10 flush();// sends buffer to browser
11 echo \n!-- for Opera --\n;// Opera seems to use a strange
buffer and does not display the last line, so send another one, invincible
12 flush();// flush again, opera should now display the line
13 }
14 unset($newline);
15
16 usleep(20);// sleep some time, otherwise the script would
eat 100% CPU. Usuable on my server (p3-550) are 10 to 50 msec
17
18 $loop++;
19 if($loop 600)
20 {
21 echo !-- TOK --\n;// some browsers kill the connection if
it is dead for some time, so send a time out kill, some minutes are enaugh
22 $loop = 0;// reset
23 }
24 }
Okay, tha's the deal..
max_execution_time is set to unlimited, I had streams running several
days. Fortunately PHP kills the scripts automatically if no brower is
listening.
To fetch a line there are some ways the most simple is to query a
database for a line with an higher id, but this eats up loads of cpu-usage
in bigger chats. Currently i use shared memory. I've an php-console-script
running wich fetches newline out of the database and writes 'em into shared
memory. This is MUCH faster than have every stream-script connecting to the
db.
What i don't know:
I'm searching for an better idea to interchange data between the scripts
wich enter data, the server and the stream-scripts. Shared memory is good
enaugh for the last two one, but it ever takes min. the 20 ms sleep-time
for a new line. I need something to awaik the script exactly when a new line
is in memory.
Synchronisation between enter and server is more difficult, because there is
the posibillity for two scripts entering a new line at the same time
don't know how to avoid this.
I hope this helps.
Hey cool,
That's working. The only problem I have now is that I want the most recent text
at the top. But that script adds it on the bottom. Any way to change that? At
least a way to always scroll automatically to the bottom?

function Scroller() {

onMouseOver=doscroll=false onMouseOut=doscroll=true
...
It scrolls down whenever the mouse is outside the frame with the stream.

Cool, the scroll script is working well.
Now, I'm working on a list that shows who's in the chat. The problem is that

Marco Tabini schrieb: Simple trick (well, not so simple, but kind of a Columbus' Egg): 1) Create an img tag in your web page that is hidden 2) Point the img tag to a php script that returns: 1) An image with a pixel width of 1 if there is new data to pick up from the server 2) An image with a pixel width of 0 otherwise 3) Create a javascript that refreshes the image every second (or every two seconds, or however often you feel necessary--the more often, the more responsive and real time your chat system will be). 4) Add an OnLoad event to the img tag that points to a Javascript that checks the width of the newly reloaded image. If the width is one, then you reload your chat text content (which you may want to put in an iframe to avoid having to reload the whole page). I don't have a script to show unfortunately, as it would probably be too complicated and long for the list (and I have no time to write it...sigh), but hopefully, this will give you the gist of it. Cheers, Marco Okay, that sounds like something i can do, i just need to know how to hide and how to point the img tag at something.

Ok, off the top of my head (please don't be upset if it doesn't work
right off, because I'm doing this from memory):
Web page:
script language=javascript
function checkimage()
{
if (document.all.image1.width == 1)
{
document.all.fr1.src=http://www.mysite.com/chat.php;;
}
}
function reloadimg()
{
document.all.image1.src=http://www.mysite.com/img.php;;
setInterval (reloadimg(), 2000); // every 2 secs
}
/script
body
iframe name=fr1 src=chat.php
img style=display=none src=http://www.mysite.com/chat.php;
onLoad=javascript:checkimage();
/body
In chat.php you simply push out whatever is in the database (the whole
thing--or you come up with some method of just printing out what has
changed since the last poll, which is trivial and beyond the point
here).
In img.php:
?
function checkdb()
{
// This returns true if new data is available
}
$filename = (checkdb() ? '1pixel.gif' : '2pixel.gif');
header (Content-type: image/gif);
readfile ($filename);
?
1pixel.gif is a one-pixel wide image, while 2pixel.gif is two pixels
wide (it just occurred to me that you can't have a zero-pixels wide
image, which would be quite pointless). The script basically reads in
either file and spits it out after setting the content type.
Once more, this script, as is, probably won't work because it was
programmed in my messy head rather than in a proper PHP environment, but
it should give you an idea of what needs to be done. In particular,
remember to use the display CSS attribute rather than visibility so
that the image will not take up any space on your page.
Also, an apology--I seem to have mailed some messages twice by mistake.
I was checking e-mail between eating my lunch and trying to get a tie on
and things might have gotten a bit out of hand ;-)
Let me know how it turns out!
Thanks, I will try that script as soon as I find some time, probably tomorrow.
But it seems to do the same thing as reloading would do: clicking all the time.
But I'll try it tomorrow.
Kind regards,
Oliver

PHP Source code is only available on the server, and will never be shown to

And you can always put your authentication data (username/passwords) in an
external include() file
auth.inc:
?
$username = foo;
$password = bar;
?
page.php:
?
include ('[secure directory outside of web tree]/auth.inc');
mysql_connect(dbname,$username,$password);
?
of course, if you are on a shared-host web server (multiple clients on the
same server), you are only as secure as the weakest idiot that
configures/administrates the server, IMHO.
Won't the server ask for authorization if the included PHP script is in an
directory accessible with .htaccess-Authorization?

Looks like a have to have a directory with write permissions where
people can upload their files to. Isn't that sort of a security risk?

[PHP] uploading pictures
Hi!
I got a problem with uploading pictures. Using a script following this
schema:
if (is_uploaded_file($HTTP_POST_FILES['userfile']['tmp_name'])) {
copy($HTTP_POST_FILES['userfile']['tmp_name'],
/place/to/put/uploaded/file);
} else {
echo Possible file upload attack. Filename: .
$HTTP_POST_FILES['userfile']['name'];
the script always returns:
Warning: Unable to create '/*.jpg': Permission denied in fotos2.php on
line 62
I do not understand why that happens. Do I need to include a password
somewhere or somehitng like that? Thank you for your help!
