RE: [PHP] Re: Tom-Re: [PHP] session hijacking
Hi Tom,
I've got a question for you regarding this encrypt class of yours.. Just
wanted to understand how well it would work against a guy with a sniffer
such as ethereal. (presuming he's on the LAN/wifi to access the app)
How does the encryption happen?? Client side or server side? How does it get
transmitted? I'm curious as to how to prevent ppl from sniffing out the
username/pass combo for these sort of sites that need memberships.
In some instances.. I can see the user/pass combo being passed in plain text
eg : user=someuserpass=somepassid=232..
or in hashed form
eg :eg :
user=someuserpass=*(^$[EMAIL
PROTECTED](J83%#396asjjuwo273314koopu83jsklid=232.
.
How does the hash happen???
snip
Save it in encrypt_class.inc
?
class encrypt_class{
var $secret;
function encrypt_class(){
$this-secret = 'you should change this to something else';
}
/snip

RE: Re[2]: [PHP] Re: Tom-Re: [PHP] session hijacking
The encryption happens server side and is really only intended to encrypt variables that are passed to web client such as product id and stuff. The only way to do secure login and prevent sniffing is to use ssl which will encrypt the traffic to and from the client. I suppose javascript could be used to fudge encryption but that would be extremely weak way to do it. To protect hidden variables you will still need to use some form of server side encryption. If you have more than one hidden variable a good way is to put them in an array, serialize it and encrypt the result and put that in a single hidden field. It would almost be impossible to interfere with those. Something like this: Hmm.. Thanks for the answer.. This question was mainly asked because I was paranoid about using Wifi to access my Yahoo Webmail. No more accessing _anything_ private over wifi or rather.. I'll have to re-think my password/privacy policy with regard to ssl/non ssl (http vs https) sites.. Better be paranoid.. One other thing.. What's the difference in $$ for a site to be https rather than http?? Cos you need to get a verisign cert or something?? Just asking.. Cheers, .^.

[PHP] Why Redirection works on 1 machine but not on another
Hi, I have this peculiar problem, my header header( Refresh:2;url=$g_prog_path/$l_refresh_url ); is set up correctly to be the FULL pathname. It works on some PC but now on some others. I'm using IE on win98/2000. The offending one is IE6 (128bit) on Win98. (IE5.5/win98 works but I've yet to try it on another win98/ie6) Any ideas?

[PHP] $_GET['sort'] argument separator
Hi,
I have this problem, which could easily be solved through a name
change but I would like to learn more.
There's a table set up from a MySQL query like this
row1) Eval # Title # Heads My Findings
row2) P1000 Title16 This is my findings
row3) P1223 Eg 2 3 2nd findings
row1 is the header columns, the title names are derived from sql statement
executed as SELECT eval_no as Eval # etc..
row1 is also set up such that if the user clicks the link, it will trigger a
SQL comand to sort it.
The problem here is the '#' sign/key. spaces are no problem. the
$_GET['sort'] is not able to get the whole field, as such Eval # can only
be recognised as Eval and thus sql is not able to sort it.
I've looked at the php.ini file and tried setting these 2 configs

It worked!!! Thanks VERY much. Now if someone could explain to me the difference between urlencode and rawurlencode.

FYI. I did this login page for another website last month and I used the
code from it to do this one. The other one works perfectly. I checked
that code again today and there is ABSOLUTELY no differnce. I even used
the same variables and session names. The only difference between the
two sites is that the one that works is running IIS on Windows 2000
Server. The broken one is on a Linux box running Apache. Both PHP and
MySQL are the same versions. Remember also that the Header redirect is
working in the redirect.inc page, which is even more confusing.
I have really given up on it. It just ain't gonna work - no matter what
I do. I thought I finally had it working again, but of course - another
f*** up.
Can you explain this? Along with my other code I used a little piece of
javascript to do the redirect, and lo and behold it worked. But now my
paths are all screwed up. I just don't get it.
In the example I tried, the page I am redirected to has a form on it.
When I click submit it should go to the page specified in the action,
which is season_write.php.
FORM onSubmit=return checkrequired(this) ACTION=season_write.php
action=post name=seasons
But for some reason it tries to go to /setup/season_write.php. This is
not specified anywhere in any of my code. So where the hell it getting
this from.
The more I use PHP the more I am becoming convinced I should be using
something else. This is just ridiculous.

In my case I use a Refresh-redirect. I've posted my code on this on this

The header_refresh_html will redirect to home.php if user is already

logging in again.
The Error msg will be display WAY.. before the refresh/redirect takes place.
(2 seconds) Maybe if through the internet it's not so great,but on my
intranet, 2 secs is long enough for the user to view the message.

just a whole lot more flexible than mine. Not to mention a bit more
secured.

From the on-line docs, regarding $_SESSION (at
http://us3.php.net/manual/en/reserved.variables.php#reserved.variables.sessi
on):
This is a 'superglobal', or automatic global, variable. This simply means
that it is available in all scopes throughout a script. You don't need to do
a global $_SESSION; to access it within functions or methods, as you do with
$HTTP_SESSION_VARS.
So, this gets more perplexing.
I should also note that I did try to use the global keyword, and it didn't
help. Also, I tried setting the $_SESSION variables in question to
something else ($_SESSION[fname] = ) before calling the function.
Didn't help either.
I have just never had a problem with sessions before. But I'm guessing it's
my code, as I can replicate the behavior on three different installations of
PHP/Apache.

Sorry all, apparently this doesn't work on either Windows or Linux.
Again, I thought it was working and once I got farther along I see that
it really wasn't. Basically what I get after I login is an empty screen.
Here is what I have :
This is the script that runs to see if the user is logged in.
session_start();
if(!$_SESSION['logged']) {
session_register('goto');
$_SESSION['goto'] = http://; . $_SERVER['SERVER_NAME'] .
$_SERVER['REQUEST_URI'];
$url = http://www.mysite.org/login/login.php;;
header(Location: $url);
}
The above works and redirects me to the login page and has the right
referring page as shown below.
goto|s:59:http://www.mysite.org/setup/inputs.php;;
This is in my login.php script. After I verify the user login is
correct, this piece of code is executed.
session_start();
session_register('logged');
session_register('user');
You don't need those two lines, they are only needed if ini.register_globals
is on and you want the variables $logged and $user to automatically be
sessioned as:
$_SESSION['logged']
$_SESSION['user']
quote
With $_SESSION, there is no need to use the session_register(),
session_unregister(), session_is_registered() functions. Session

I think this is were your problem is.
Also what php version?
quote CAUTION
If you are using $_SESSION and disable register_globals, do not use
session_register(), session_is_registered() and session_unregister(), if
your scripts shall work in PHP 4.2 and earlier. You can use these
functions in 4.3 and later.
/quote
Hmm.. After looking at the session_* documentation there are CAUTIONS
all over the place.. The all seem to say dont use sesion_register,
unregister, and is_registered when your using $_SESSION;
$_SESSION['logged'] = True;
$_SESSION['user'] = $row['user'];
$target = Location: . $_SESSION['goto'];
session_unregister('goto');
Use: unset($_SESSION['goto']);
header($target);
what does echo($target) yeild?
What I get after this is a blank page. The user has been logged in and
shows in the session file, but it just isn't redirecting.

Yes.
If you use only the $_SESSION array to set/get the values of your session
variables, you do not need (and, in some versions of PHP, MUST NOT use)
session_register() or any of its friends.
The proper coding for what you are doing above is:
session_start();
$_SESSION['username'] = $row['username'];
$_SESSION['user_id'] = $row['user_id'];
$_SESSION['access_level'] = $row['access_level'];
and
if (isset($_SESSION['user_id']) )
{
return true;
}
else
{
return false;
}
(or even just
return isset($_SESSION['user_id']);
! ;)

Are you outputting BLANK LINES???
eg.. if you have blank lines after your last ? (closing PHP tag) in
ANY one of the require/include/script files, you're outputting something and
this cannot be the case.
eg. if in VI
echo $someecho
function dosomethig()
{
// whatever
}
?
- THIS blank line will be regarded as Output. Hence You can't
redirect!

If I echo $_SESSION['goto'] right after session_start() it shows

Have you checked your error logs? You should always, ALWAYS have error

an

Does it work if you have a single line script:

[PHP] Howto list Mysql Table Headers using PHP
Hi,
Got a quick question.. How do I get the table headers also
printed/retrieved by PHP for 'echo'??
eg :
1 +--+--+-++
2 | Drive SN | HSA DCM | Family | Media Supplier |
3 +--+--+-++
4 | WMACK001 | GD223213JHHS | PIONEER | KOMAG |
5 | WMACK002 | GH37489284HH | PIONEER | FUJI |
6 | WMACK003 | F023213JHHS | XBOX| KOMAG |
7 | WMACK004 | FV23213JHHS | XBOX||
8 +--+--+-++
The coding can get rows 4-7 printed out but I would like to get row2 printed
out as well. The table's all set up for it already.
I'm using
$result = mysql_query($sql);
$num_results = mysql_num_rows($result);
for ($i = 0; $i $num_results ; $i++)
{
echo tr\n ;
$row = mysql_fetch_row($result);
for ($j = 0; $j sizeof($row) ; $j++)
{
echo \t . 'td';
echo $row[$j] ;
echo /td \n;
}
echo /tr\n;
}

Subject: Something to watch look for when getting HEADER Warnings
Recently, I ran into a problem where I continually got a Header already
sent message.
I took me a while to figure out because the file that was included
only contained function definitions, or so I thought.
After the closing php tag, I had a new line with a single space on it.
This space was, in turn, sent to the browser.
file.php begin (blah, not working) -
?php
function seomthing()
{ //do something
}
?[enter]
[space]
file.php end --
It wasn't until I removed the single space and any additional newlines
that all worked fine.
Any non-null lines outside of the php tags will results in voiding all
rights to send any header or cache information, and this includes
space or newline characters.
Just an FYI.
file.php begin (cool, it works now) -
?php
function seomthing()
{ //do something
}
?[no newline]
file.php end --
Actually, you can have a newline after the clsoing php tab, but if you
have a
non-null string following that (this includes newline characters), bad
bad stuff can happen.

No, it's a configuration file. An argument list is the bit between the
parentheses when you write a function call:
$retval = some_func($this, $is, $the, $argument, $list);
If your config file had all of those variables in an array or something,
and you passed that array to your function, *that* would be an argument
list.
See below:
config.php:
?php
$config = array('logout' = 1,
'overall_summary' = 'Here is the summary',
etc);
?
script.php:
?php
include('config.php');
display_menu_html($config);
?
Problem solved. The only thing left which can conflict is the name
$config, and you could solve that by calling it something you're sure
nobody else will be using (maybe $_omh_config or something). Now, you
can lift your config file and display_menu_html() function and drop
them into pretty much any script and be much more sure that you won't
have to crawl through all the code making sure there are no variable
name conflicts.
The other way would be to write a function that obtains that from the
argument list. But as I see it, it's basically the same thing? NO?
No, because say you want to use this function in another script. First
you need to make sure that this new script isn't already using any
globals with any of the names you want to use--otherwise, you'll have
variable clashes--where you expect one thing to be in $logout, for
instance, but the script is using the name $logout for something else,
and the value isn't what you expect.
Class.. That's not somewhere I would want to venture, not right now
anyway.

[PHP] Too much of $GLOBALS[] a problem??
Hi All,
Just a quick question on this. In my scripts, I'm using A LOT Of
$GLOBALS['my_parameter'] to get the declared values/string. 1 example below
:
function display_menu_html()
{
echo 'table class=width100 cellspacing=0'.\n;
echo 'tr'.\n;
echo \t.'td class=menu'.\n;
echo \t.'a href=home.php' . $GLOBALS['home'] . /a
nbsp|\n;
echo \t.'a href=view_tracker.php' . $GLOBALS['view_tracker'] .
/a nbsp|\n;
echo \t.'a href=initialise_fa.php' . $GLOBALS['initialise_fa']
. /a nbsp|\n;
echo \t.'a href=mass_initialiase_fa.php' .
$GLOBALS['mass_initialiase_fa'] . /a nbsp|\n;
echo \t.'a href=Summary.php' . $GLOBALS['overall_summary'] .
/a nbsp|\n;
echo \t.'a href=account.php' . $GLOBALS['edit_account'] .
/a nbsp|\n;
echo \t.'a href=logout.php' . $GLOBALS['logout'] . /a
nbsp|\n;
echo \t/td\n;
echo \t.'td class=right style=white-space: nowrap'.\n;
echo \t.'form input=post action=jump_to_fa.php'.\n;
echo \t.'input type=text name=fa_id size=12
class=bold-small /'.\n;
echo \t.'input type=submit value=' . $GLOBALS['goto_fa'] . '
class=small / '.\n;
echo /form\n;
echo \t/td\n;
echo /tr\n;
echo /table\n;
}
This isn't really a Problem but.. is it bad programming practice?? Or I
should just write another function that can return the values/string?
Any thots?

Hi, Unfortunately, Yahoo.com is just an example.. The site really does need Login. The thing is this, I'm developing for an internal site, (My dept) but I need to access other dept's site to get info but unfortunately They won't give me access to query the db directly. Prefering me to go through the site and input accordingly to grab the data. I just find this to be SO troublesome as I need to get this data for every week. Week In..

I'm not sure about FreeBSD but on Redhat, the /etc/passwd 'IS' meant to be world readable. But fortunately it's only stores usernames and Real names and etc.. whereas /etc/shadow is only root readable and it's the file that stores user's passwords. I think that's pretty secure. Why are you parsing through /etc/passwd anyway? Anyway, I might have gotten your question wrongly or something.

define global

variable.
One other quick question, in my original code (per below) the function
create_global() was used to create_globals on demand. But
this involved a
lot of jumping, from one function to another just to create
the globals on
demand. Is this efficient (more?? less??) compared to just
stating global
$page_title inside the function?
I don't think create_global() is of any use to you in this situation --
you're just wasting the time taken to do the function call and return. Just
do either:
function org_display_title_code()
{
global $page_title;
echo 'This is title1 - ' . $page_title;
}
Or:
function org_display_title_code()
{
echo 'This is title1 - ' . $GLOBALS['page_title'];
}

Here's the thing.. I declared $page_title = My Page Title in a

to - echo $page_title - Nothing comes out.
If I declared it as global $page_title , then My Page Title would

Here's My question, a variable is not actually global is not
actually global until I make it global through global
$make_this_global
and then I can assess it using $GLOBAL[$make_this_global].
Not correct.
Variables used in the global scope are global, and appear in the $GLOBALS
array as soon as they come into existence. A global statement is used
within a function merely to declare that you wish to use one of those
variables in that function, where it would otherwise not be available. It's
sort of equivalent to saying when I use variable $x in this function, I
actually want it to be $GLOBALS['x'] -- or, in PHP terms, $x =
$GLOBALS['x'].
Another method would be to globalise it on demand by writing a
little function. (like Rasmus)
I did it like this --
---create_globals.php
function create_global($passed_variable)
if (isset ($GLOBALS[$passed_variable]))
{
return $GLOBALS[$passed_variable];
}
---end-
config.php--
$page_title = Page Title of Web Page
-end
--index.html
require_once ('create_globals.php');
$local_variable = create_global( 'main_title')
echo My Page Title is.$local_variable;
--end-
Hence This way I can make it global-on-demand.
Maybe a better way to do it would be to
---config.php---
global $page_title = Alternative Way
end-
I'm really not sure what you're getting at here, but I think it may be based
on a misunderstanding. If you could explain exactly what it is you're
trying to do, someone might be able to offer some better help.
Cheers!

The only problem here would be the EXTRA typing involved. The other
problem/question is, will there be a speed tradeoff? If I were to global'ise
everything at the 1st place, would it be faster than jumping in and out of
create_global() and going through $page_title whatever other variables? (I

Hi,
If the file you are including is of your own authorage (I know that
isn't a word, but whatever :), just refer to global variables always as
an index of the $GLOBALS array. This is good practice anyways for any
file that might be included by another user, for exactly this issue.
I have a file that could be a global include or not in my project, and
making sure every global variable is referenced as $GLOBALS['varname']
fixed it for me without any fancy code (although Rasmus's code is very nice)

work like this, but my testing indicates it does not. Everything stays
local to the function and goes away when the function ends.
Is there a way?
Functions defined in included files are always global. So I guess it is
just the variable you want to put out into the global symbol table. It's
a little bit tricky, but you can do it like this:
function foo($filename) {
extract($GLOBALS, EXTR_REFS);
include $filename;
$arr = array_diff(get_defined_vars(),$GLOBALS);
foreach($arr as $var=$val) $GLOBALS[$var] = $val;

These modes are called MPM's. The default MPM is called Worker which is a multithreaded model. PHP, mod_perl, mod_python, and any other similar technology which links directly into the httpd processes will need to be perfectly threadsafe and reentrant to work effectively with a threaded Apache2 mpm. This is doable for the core of PHP, but there are literally hundreds of 3rd party libraries that can be linked into PHP and nobody whether or not these libraries are threadsafe. And figuring out if a specific library is threadsafe or not is non-trivial and it can very from one platform to another. And just to make it even harder, this stuff will appear to work fine until you put it under load or hit very specific race conditions which makes it nearly impossible to debug. So, since we can't tell you for sure that a threaded Apache2 mpm + PHP will work we do not suggest you use it for a production server. And since we can't know for sure, none of the main PHP developers use this combination for our own servers which compounds the problem because it is not receiving anywhere near the amount of realworld testing required to work out all the little issues above and beyond this threading unknown. There is an Apache2 mpm, called prefork, which isn't threaded and basically makes Apache2 look like Apache1. But hey, we have a very good server already that looks like Apache1. In the end I don't see Apache2+PHP ever becoming a production platform with the current architecture. The only way I see it ever working is to pull PHP out of Apache and use a fastcgi approach.

[PHP] Session vs Cookie Issues
Hi All, I know this topic has been talked about a LOT but all the info I've managed to get from google is that there is no center / best option to choose between using sessions or cookies. Pros of Sessions 1. PHP does it all automatically 2. Can also be defined but I don't know how(yet) Cons 1. saves it in /tmp - world viewable 2. Session ID may be easy to guess unless I md5 the sessionID before sending it out Pros of Cookies 1. can be generated via functions 2. Can be stored in mysql looked up each time user comes to the site (this i found out from mantis-bugtracker) 3. can be set using PHP setcookie function Cons 1. cookies can be rejected by users 2. if rejected, means session can't be preserved across pages?? (this I'm not sure) 3. cookie is stored in user's hard drive. What is user using public PC? Can anyone please help explain which is better in terms of performance security? For cookies and the way that mantis does it(I looked through the code to learn - newb), each time a page is accessed, php will query the database for the cookie string and compare it as a means of identification. Doesn't this affects performance if I were to need to query the database A LOT? (presuming that my site generates a lot of traffic.) I'm assuming here that accessing the /tmp is faster than accessing the database. Is there a way to put the /tmp location somewhere secure and not world viewable? Please Don't flame me.. I'm just asking. Cheers, Mun Heng, Ow H/M Engineering Western Digital M'sia DID : 03-7870 5168 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] Session vs Cookie Issues
Hi Mike, based on what you're saying, I gather that if I were to choose to use cookies, and if cookies were rejected by the user, PHP will default to using sessions? : quote :--- The only major flaw I've found with PHP's session support is that it doesn't appear to be possible to force the data to be written without also closing the session. : End Quote : Is the above a serious flaw which I need to be aware of?

You're comparing apples and oranges -- cookies are one of the mechanisms by which PHP implements sessions. The other is URL-munging. So if you use sessions, odds are cookies are coming along for the ride. What you definitely /don't/ want to do is to store application data in the cookie itself, due to various security (public machines) and technical (4k size limit) concerns. PHP's built-in session support uses the cookie data as an identifier, to match a user to the data stored in a session file, and in general this is the way to go. The only major flaw I've found with PHP's session support is that it doesn't appear to be possible to force the data to be written without also closing the session. In general, PHP's session features are pretty complete, and easily modifiable. To clear up a few items below: Cons of Sessions 1. saves it in /tmp - world viewable not necessarily so, see php.net/session_save_path 2. Session ID may be easy to guess unless I md5 the sessionID before sending it out you can define your own session id if you'd like, see php.net/session_id for example, to help deter session fixation, you might require that the session be a hash of certain environment variables, such as remote IP or user-agent string. Cons of cookies 1. cookies can be rejected by users 2. if rejected, means session can't be preserved across pages?? (this I'm not sure) this is where URL-munging will come into play; PHP will resort to this if cookies are rejected. 3. cookie is stored in user's hard drive. What is user using public PC? don't use the cookie to store application data - use it to determine the user's identity. This is the behavior that PHP's session features encapsulate. - michal migurski- contact info and pgp key: sf/cahttp://mike.teczno.com/contact.html -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] PHP cached data when using browser back button
Hi All, How can I prevent the browser from sending in cached data after the user pressed the 'back' button and re-inputted data. Eg: Originall I enter 3 isbn numbers, submitted it, then the user presses the 'back' button to re-input 1 new data and then re-submits the data, instead of only having the 1 new data, I get the 1 new data + 3 old data. Can anyone help explain this? (if I were to clear the browser's cache, then there's no problem.)

RE: [PHP] Q : HELP HTML forms parsed into an array for PHP
Hi Jason,
Sorry but your code doesn't work. I tried fiddling with it but since
I'm a newbie, I'm a bit lost.
for lines that has '$isbn - should it read '$isbn'?
After submitting the form to itself, I tried to echo the $status, $newisdn
but nothing comes out.
For The Javascript, can I ask you if it's possible for the focus to go from
Input1 to input2 consequtively? eg:
|-| |-|
| ISBN Box| | SKU number| SUBMIT
|-| |-|
Scan at 'ISBN Box', focus goes to 'SKU number' and then subsequently it
submits the data into the server.
Okay.. here's what I'm trying to prove.
I have a bunch of books, which I need to scan in the ISBN the
corresponding SKU number and then submit it to mySQL.
@ 1st i was thinking I can just scan in the list of ISBN numbers and then go
to another box and scan in the SKU numbers and then input them into MySQL
together(but then I'll be opening up another can of worms to match ISBN to
SKU for each line!). If I do that, I won't be able to determine if there's
duplicate entries before I submit it.
John Holmes solution worked but needed a few tweaks for the \n and \r the
scanner puts in automatically.
If anyone can point me in the right direction, please help.

Subject: Re: [PHP] Q : HELP HTML forms parsed into an array for PHP
from what i've experienced w/ bar code scanners, they send a carriage return
after inputting the numbers, so why not just have a page w/ a single input
text field and a submit button that submits to itself? i threw in some
javascript, also, that should set focus to the text field when the page
loads, so if you are scanning in a bunch of items, you scan, it
automatically submits, and is ready for the next one.
that's the idea, anyway, assuming your bar code scanner is setup to send a
carriage return signal.
name of page is form.php:
?php
$cn = mysql_connect(localhost,username,password);
$db = mysql_select_db(mydatabase);
if ($status==newisbn) {
$isbn= trim($isbn);
$sql = select * from table where isbn = '$isbn;
$q = mysq_query($sql);
$nr = mysql_num_rows($q);
if ($nr 1) {
$sql = insert into table (isbn) values ('$isbn);
$q = mysql_query($sql);
echo Successful insert.br;
} else {
echo ISBN already exists. $newisbnbr;
}
}
?
html
body onLoad=document.getElementById('isbn').focus()
form name=myform method=post action=form.php
Input:input type=text id=isbn name=isbn

Hi all,
Really hope someone can help me out.
What I would like to do is to input multiple isbn numbers into a form, get
PHP to parse it into an array so that I can build the SQL query for
multiple
insert. Currently I'm able to perform single inputs, one at a time, which
is
time consuming.
I want to have a formtextarea name=isbn row=10 col=13 set up to get user
input (multiline, each line separated by a carriage return - actually it's
barcode is scanned in)
eg : ISBN - 1-111-2-1
1-111-2-2
1-111-2-3
I would like to parse this data into PHP and get PHP to use a foreach loop
(or a for loop) so that I can build up the $query to form ('isbn1')
('isbn2') ('isbn3').
I'm trying to insert into mySQL a multiple value insert sort of like
$query = insert into table values
('isbn1')
('isbn2')
('isbn3');

Mun Heng, Ow
