Hi Everyone,
I'm attempting to figure out the proper way to use sessions to log
someone into my system. The idea being, if they arn't logged in all
they can see is the login form, and if they are logged in, they and
have access to a database of addresses.
[snip!]
Not the end-all-be-all, of course, but here's the basics:
<?
session_start();
if(!$_SESSION['user']) {
if($_POST['user'] && $_POST['pass']) { // Keep in mind, PASSWORD
has meaning in MySQL
// Do your string sanitizing here
// (e.g. - $user = mysql_real_escape_string($_POST['user']);)
$sql = "SELECT * FROM users WHERE user='".$user."' AND
pass='".$pass."' LIMIT 0,1;";
$result = mysql_query($sql) or die("Wrong data supplied or
database error");
while($row = mysql_fetch_array($result)) {
$_SESSION['user'] = $row['user'];
// Do whatever else you need to do here....
}
} else {
// Show your login form here.
}
} else {
// The user is authenticated and logged in already.
}
?>
Keep in mind that, as always, this hasn't been bug-checked,
re-read, or otherwise validated.
Hey Dan,
Thanks for the response, I think I see and understand what you are
trying to say in there, but I am hitting a road block now... It won't
display the page. I have tried to both just include the page, and
copied the entire page and pasted it in the proper location.
Any ideas? Here's the code... And no I still haven't added
mysql_real_escape_string yet... Want to get 1 part working at a
time :) Fewer issues in my head then.
<?PHP
include 'defaults.php';
include 'dbconnect.php';
session_start();
if(!$_SESSION['user']) {
if($_POST['user'] && $_POST['pass']) { // Keep in mind, PASSWORD
has meaning in MySQL
// Do your string sanitizing here
// (e.g. - $user = mysql_real_escape_string($_POST['user']);)
$sql = "SELECT * FROM login WHERE loginid='".$user."' AND
email='".$pass."' LIMIT 0,1;";
$result = mysql_query($sql) or die("Wrong data supplied or
database error");
while($row = mysql_fetch_array($result)) {
$_SESSION['user'] = $row['user'];
// Do whatever else you need to do here....
echo "First Part";
include "index.php";
}
} else {
// Show your login form here.
echo "
<form method=\"post\">
Username : <input type=\"text\" name=\"user\"><br />
Password : <input type=\"password\" name=\"pass\"><br />
<input type=\"submit\" value=\"Login\">
</form>";
echo "Second Part";
}
} else {
// The user is authenticated and logged in already.
echo "Just before include";
include "index.php";
echo "Third part";
}
?>
The few echo's that are in there are only there for debugging, easier
to see how far I get :)
Thanks for looking! :)

Sounds to me like you're not getting through the while() clause,
meaning that there's no matching rows in the database.
$sql = "SELECT * FROM login WHERE loginid='".$user."' AND
email='".$pass."' LIMIT 0,1;";
Is the password they supply in the `email` column of the database?
Yes it is... For now... I am just using test/test and I had a field
named password in the database but thought that was messing it up, so
I dropped that field and currently I am just using the e-mail field
as a password.
Once it works I'll change the field to a more appropriate selection
with MD5 hashing, and maybe even a little salt in the hash. (Gotta
add the flavor!)

If you have phpMyAdmin installed on that server, J, try using the
"search" tab to see if you can find that user/email combination in the
database using = and not LIKE.
Perhaps there's a whitespace or something of the like that's
causing it to return zero rows.
Also, try doing this after the $result = mysql_query($sql); line:
die("Number of rows returned by MySQL: ".mysql_num_rows($result));

I don't have phpMyAdmin installed, never saw the need to... But I'll
look into it in the future.
And after adding the die that you recommended, you were right, it
wasn't returning any rows. So... I did some checking and it's amazing
sometimes that you can't see the trees through the forrest.... a
simple $user =$_POST['user']; and $pass=$_POST['pass']; and all is
well. It logs into the page, now I just need to fine tune it since it
doesn't like to display the actual database now, but that's something
I should be able to figure out.
One other question, to logout, can I just call a file that has
session_destroy() and a header("Location: ???"); in it? Or should I
do something else for logging out?
Thanks again! Without your help... I wouldn't be able to do this!

For my purposes, I simply do a session_destroy();, but some people
may prefer to do an unset for their own purposes.

Yes, a single sign-on it is... It doesn't work together with Windows
(and
PHP) you mean?
[/snip]
No, not really.
You can run PHP on a Linux or a Windows server and it does not have
access to the initial login values (press cntl alt del to login)
although ASP and .Net (auth_user, etc) do. This is something that I have
wanted to do for years and we have even discussed on this list.
The initial login has to be configured so that the computer is
accessible either online or off and it can be either basic (plain text)
or challenge/response (encrypted). If it is online it will typically
look at an Active Directory server for authentication using LDAP as the
method of communication. If it is offline the login will typically look
at registry settings to determine if the login is authorized.
Since PHP cannot read registry settings (neither can JavaScript) on the
client that is out. Windows is aware of the logged in user, but exactly
where that 'session' information is kept is a mystery to most of us. So
PHP cannot be aware of a user who has performed the initial login.
What we shoot for is Single Source Authentication. SSA uses LDAP to
connect to AD for authentication purposes. It requires that the user
login to each application, but since we are using the same
authentication platform (within a corporate system) their username and
password combo is the same as their initial login. If they change their
password (which we can make them do on a regular basis using AD's
password policies or they can do on their own -- we can also enforce
password strength) then they are able to continue using the new password
throughout the applications.
This is a very high level overview and it doesn't even begin to talk
about role or group management, but it is how we mitigate the
username/password issue for corporate users. For a public web site the
method may be quite a bit different.

i know there is an apache NTLM(1) module for this. i don't believe it
requires anything other than a connection to a domain authentication
server and the ability to send headers and read the reply
(challenge/response) - i don't think the registry is needed at all on
the client or the server.
(1) http://modntlm.sourceforge.net/ - just one example

True, but it appears that many of these are not ready for prime time and
require an extensive amount of configuration (sometimes even modifying
the registry).

yeah, i didn't say this would, but it should be able to be ported to a
PHP module by someone i would think. i mean if someone can do it in
Perl or C (especially C) why can't it just be changed to work under
zend/etc?

This topics subject ("Why?") is not related. I thinks its better to change
it and create another thread. it'll be better for other who already doesn't
know what the actual topic is.

Hello people,
i have a question??
I have an application written in c++ and this throw real time data as
udp-pakets all the time (interval 1 min and values in a wrapper like an
own protocol are floats and longs).
Is there any possibility to catch the udp packets - parse the pakets und
show the values in tables in a html-doc in real time???
What technologies are good? ajax? cgi? ive no idea!!!!!

you can use sockets in php, they work the same as berkley sockets
you can use system() in php, to call your C++ program (the program
could output html)
in my opinon CGI with C/C++ is obsolete, use php/apache for best results!
another nice way is to have your C++ program independent, outputs its
results/values into a database (mysql)... and a php page will just
read what's in the database to display it nicely.
That would be a clean way of doing it.
Good luck!

That's what we do here. C/C++ app gathers and inserts the data into the db,
minute by minute, and PHP apps are used for display, reports, graphics,
etc... Our LAMP system has had nary a glitch in over 3 years of continuous
usage.
That would be a clean way of doing it.

Barev David,
I think this is solution
1. C/C++ updates database (MySQL or other)
2. There is some PHP file that is viewing your DB info(printing static info)
3. There is other PHP file that is using AJAX for interactive update of
information (This one is sending request to first PHP file and if needed
updating second one)
I don't know maybe this is very complex, but I would choose this one ;)
Best,
Gevorg

No, this is not that tough. we did it before.
1. A C program retrieves data from several (more than 100) servers.
2. It saves the data in the MySQL db.
3. A php page is loaded with an ajax enabled
4. then a ajax call is sent to the same php file. it uses the setTimeout
function.
5. Data comes in json format.
6. data is formated by javascript and shown in the page.
Thats it.

Hello people,
i have a question??
I have an application written in c++ and this throw real time data as
udp-pakets all the time (interval 1 min and values in a wrapper like an
own protocol are floats and longs).
Is there any possibility to catch the udp packets - parse the pakets und
show the values in tables in a html-doc in real time???
What technologies are good? ajax? cgi? ive no idea!!!!!

I recently built a PHP daemon. It uses sockets to listen on a given port for
UDP packets.
Take in a request, processes, decides what it needs to do based off the request and then takes
action. Once it is done with said action, starts listening again. This process is done a few times
a second. I have it logging connections to a DB and saving other information to a log file in the
file system.
You could easily take something like this and create a daemon that would listen for incoming
connections and from the data it gets build a page and drop that onto the file system.
here is an example of what I do
<?php
define('LISTEN_IP', 'X.X.X.X'); // IP to listin on '0.0.0.0' would
listen on all IP's
define('LISTEN_PORT', 8080); // Port number to listen on (8080)
define('PACKET_SIZE', 512); // 512 bytes
if ( $socket = @stream_socket_server('udp://'.LISTEN_IP.':'.LISTEN_PORT, $errno, $errstr,
STREAM_SERVER_BIND) ) {
while ( true ) {
$packet = '';
while ( $buff = stream_socket_recvfrom($socket, PACKET_SIZE, 0,
$remote_ip) ) {
$packet .= $buff;
}
// if need be, loop this until you get to the end of your
packet/information
while ( !empty($buff) ) {
$buff = stream_socket_recvfrom($socket, PACKET_SIZE, 0,
$remote_ip);
}
// work with $buff here to capture all your data.
// Then also figure out when and if you need to exit
}
fclose($socket);
}

I'm curious as to how everyone organises and includes their classes in

Then have a config file of some sort in which you specify your DB credentials.
There's a variety of ways to do that (ini file, a PHP file with a database
url, a PHP file that just has a couple of variables in it, or constants
instead, etc.). Pick one you like. Then have your DB connection class read
that file's data one way or another and connect as appropriate.
If you have to modify anything other than a single config file in order to
move your site/app from one server to another, then you have a design flaw.
(I'd say that applies for moving the site to a subdirectory on a server too,
but that takes a bit more effort.)
I'm with Larry on this. Include a constants file at the top of your
scripts. In that file you can place a switch block that tests for the
$_SERVER['HTTP_HOST']. For each case, place something like:
define('DB_NAME', 'my_dev_db');
Other things this is useful for are setting a boolean constant that a
class might test in, eg. a toString method or error handling, and email
addresses for scripts that phone the client. If you have a bunch of
different ones it might be easiest to define dev & test email addresses
first and, in the switch block, set the others accordingly. So, say you
have several email addresses for various things being sent to client
employees (sales@, admin@, jobs@, etc.). You can do something like:
define('EMAIL_DEV', '[EMAIL PROTECTED]');
...
switch($_SERVER['HTTP_HOST'])
{
...
case 'dev.myclient.mycompany.com':
define('MY_APP_DEBUG', TRUE);
define('DB_NAME', 'my_dev_db');
define('EMAIL_SALES', EMAIL_DEV);
define('EMAIL_ADMIN', EMAIL_DEV);
define('EMAIL_JOBS', EMAIL_DEV);
...
break;
No muss. No fuss.

Thanks Jim,
Your sugestion worked perfect for me!!
I have another question:
After i validate this URL i want to put a link with this URL in my page.
The problem is that if the URL is like (www.aol.com), when i create the
link, this URL is appended with the URL of my site. The result is a link
pointing to: http://<mywebsite>/www.aol.com
But if the URL is like (http://aol.com), then the link is created correct.
Is there a way to avoid the first situation... so the link is created
correct?
Thanks again,
Wagner.

This should be preg_match('/.../i', $_POST['website'])
your regex should look something like this.
^((ftp|(http(s)?))://)?(\.?([a-z0-9-]+))+\.[a-z]{2,6}(:[0-9]{1,5})?(/[a-zA-Z
0-9.,;\?|\'+&%\$#=~_-]+)*$
So, put it all together and it should look like this.
<?php
$url = "...PUT YOUR TEST URL HERE...";
if (
preg_match('!^((ftp|(http(s)?))://)?(\.?([a-z0-9-]+))+\.[a-z]{2,6}(:[0-9]{1,
5})?(/[a-zA-Z0-9.,;\?|\'+&%\$#=~_-]+)*$!i',
$url) ) {
echo "Matched";
} else {
echo "Did not match";

you must use http://www.aol.com not www.aol.com. coz the later is not a
valid url. The protocol is not specified there. and if you use
www.aol.comis your href of a tags, the browser will automatically add
your current web
address as prefix as if its a relative url.
if your site is http://www.example.com/folder/site.html
and if you use href="/www.aol.com" it will show http://www.example.com/
www.aol.com
if you use href="www.aol.com" it will show
http://www.example.com/folder/<http://www.aol.com/>
www.aol.com
you have to use href="http://www.aol.com"; the absolute one.

You could always do a string comparison for http(s)? in the url
if ( strpos($url, array('https://', 'http://')) === false ) {
$url = 'http://'.$url;
}

Hi!

Kind Regards Emil Edeholt
The output buffering maybe would be unstable your php application in
some cases. May be it so slowly in some versions of php and depend of
the web server that you have mounted your php. And it uses memory this
point is so clearly.
If you want to create cookies server/client "on the fly" you may need
ajax, with this asynchronus requests you put headers and cookies
instead, and use it on the fly in the browser if the http request is ok.
Are you know the session variables, maybe you need that.
Well, the desicion is yours. tell us what you want to do.
