What version of phpBB? I know there were a number of security fixes in
the last few releases (current looks to be 1.4.4)...

1.4.0 was hacked, but just for fun on tuesday, on wednesday I upgraded to
1.4.2 and it was hacked by another hacker in the night!!!
I looked at the 1.4.2 for my customization, and this morning at the 1.4.4
and saw that even basic security holes are not fixed. The project team is
working on the 2.0 so I think the release is not serious.
I spent all the day to recover the defaced topics and texts, now I gonna
backup and think to another solution...
Thanks for the reply anyway,
Jimmy

Hi all,
I've just finish upgrading my apache server to apache 1.3.22,
I have also compiled my php-4.0.6 with it.
When I try to test it using
<? php phpinfo(); ?> saved as php, the browser tries to download it instead.
I have added the application type under httpd.conf and restarted the server
./apachectl restart.
when I type
./apachectl status it does not show that the php-4.0.6 has be compiled with
it.
Am i missing some steps? please point me out,
p.s. i have added the module of php4 /libphp4.a to apache
and did the make command to make it executable.
Thanks,

Probably not your problem but shouldn't your php line be as follows:
<?php phpinfo(); ?>
ie without the space between <? and php?

Make sure that there is no output from your PHP script - or any HTML code
whatsoever - before you call the header function.

Good day!
Is there any way to get names of vars and values from $HTTP_POST_VARS if I
don't know their names and (ofcourse) values? (number can be taken from
count($HTTP_POST_VARS) ) ...
This is nesesery to write a function wich write log of user's work with
remote filesystem.

RTFM
HTTP_POST_VARS is an array, so you can iterate with forach:
foreeach($HTTP_POST_VARS as $variableName => $variableValue){
echo "<P>In Variable $variableName you submitted:
".htmlentities($variableValue)."</P>\n";
}
For further information go on http://www.php.net, there is a _very_ good
documentation. (For this topic look at "array functions")

echo "$key = $val<br>\n";

a great way to debug things like this is to use var_dump or print_r...
http://www.php.net/manual/en/function.var-dump.php
http://www.php.net/manual/en/function.print-r.php
<pre>
<?php var_dump($HTTP_POST_VARS); ?>

short and simple :)

Hello,
For reasons not worth discussing here, I have to develop and test on
Linux/Apache some PHP pages that will have to access via ODBC a MS Access database on
an NT/IIS/PHP server.
I would like to do it by writing PHP pages that access via ODBC
some mysql or other database on my linux box, in such a way that,
if it works there, I just change some general setting, upload the pages
and they work for sure on the MS Access thing (something like:
ifdef LINUX then ODBC_ACCESSES_MYSQL
ifdef NT then ODBC_ACCESSES_MS_Access)
I am sure that this must be possible, but would really appreciate some
examples/pointers to specific tutorial/similar stories/etc.
TIA,
mweb

Can someone explain to me why sessions don't work with SSI?
Let me explain my case:
I have a php script called miec.php, which uses sessions extensively. It's
a script to show products from a catalog randomly, and in the session it
keeps the products already shown, so it doesn't repeat... it works just fine.
So... if I go to my browser and point to miec.php, and keep reloading it, I
can see it working... the sessions get updated perfectly and then reseted
when the maxinum number of allowed products is reached...
Then I have another file called test.shtml which includes miec.php via SSI
(<!--#include virtual="miec.php"-->), the include is perfect... even the
cookies holding the userId works... but the session simply doesn't work...
When I load test.shtml, a session is create by miec.php, I can even see the
file on the server. But if I reload the page, another session is created
instead of using the same, so it's not persistent... thus, it doesn't work
at all.
The weird thing is: if I call miec.php directly, the session gets created
normally, if then I point the browser to test.shtml, the session persists
normally, and then everything works as expected... I believe this is not
the expected behaviour...
Does sessions work with SSI or not?

I’m using PHP to allow a user to update several MySql records in a batch
process. During the update I print to the browser information about the
update (records deleted, added, changed…etc.). What I would like to do
is also save this report so the user can access it at a later time.
I’m considering writing all the update information to a datafile before
displaying it to the user, say through an include(); What I would like
to do is direct the output (all my prints) to that report file. It seems
though that I might have to go through my code and explicitly use fputs
to accomplish this task.
Any suggestions welcome.
Thanks,
Chris

have a look at "output buffering"
http://www.php.net/manual/en/function.ob-start.php
this way you can send output you actually send to the browser save in
a buffer and do with it whatever u want :-)

It appears this function is only available for PHP4+. I have been trying
to stay compatible with PHP3 but maybe I should abandon this requirement.
Do you know of any URLs that may provide stats on versions of PHP in use?
Thanks,

I have been troubleshooting the performance of some code for a couple of
days and I have not been able to find out what is happening.
Here's the pseudo-code
- Get jobs from the MySql database. Return all customers. Returns 10 rows.
then for each customer return their active jobs. ( About 1 to 2 rows ).
- for each row build and array entry which looks like the following
Array Customers
{
Array CustInfo()
{
Array Job 1 Info
Array Functions()
Array Details()
Array Job 2 Info
Array Functions()
Array Details()
}
Array CustInfo()
{
Array Job 1 Info
Array Functions()
Array Details()
Array Job 2 Info
Array Functions()
Array Details()
}
}
There may be more than one customer (CustInfo) stored. The problem is
that under Windows 2000 server the code that builds the array takes 1/1000
of second to execute for each item added to the custinfo array. When I move
the same code and database to my Red Hat 7.1 Linux server it takes 2/100 of
a second!! So the whole process of building the arrays takes a total of
2/10th of a second under Windows 2000 server and takes 2 seconds on the
Linux server.
I have never seen this kind of issue before under Linux and was wondering
what it could be? PHP Config option? Linux config option?
Specs of the Servers
=================================
The Windows 2000 server is a 600Mhz Pentium with 384Megs ram
The Linux server is Red Hat 7.1 on a Dual gighz server with 512 megs ram..
Both servers are running php 4.0.6.
There is no load on the Linux server to affect the numbers. All other
processes including other PHP code runs great and much faster than Windows
2000.
Any advice would be appreciated.

Happy Friday!
I don't know anything about the innards of the PHP/Apache relationship. I am
wondering if there is a security advantage to using the getenv() function to
access an environment variable, instead of using the $HTTP_SERVER_VARS
array, or, if register_globals is on, the global version of the variable.
Using $SERVER_NAME as an example, and assuming register_globals is on, if
$foo = gentenv("SERVER_NAME");
$bar = $HTTP_SERVER_VARS["SERVER_NAME"];
are $foo, $bar and $SERVER_NAME guaranteed to have the same value? Can a
cracker poison one of these but not the other? Does getenv() get the value
from Apache or PHP's namespace?
You know what I'm getting at, right? ;)
TIA
Happy Friday!

have a look at get_html_translation_table() in the php manual.
there is an example of conversion of all special chars so they can be
inserted into the database as text (i.e. £>£) and a cool way of
'decoding' them if you need to write them to a file. A Browser wil interpret
them correctly when they are displayed.
This must be the question of the day as i have posted this answer three
times today :-)
Let me know if you need any more help
Steve
get_html_translation_table manual page is below:
PHP Manual
Prev Next
----------------------------------------------------------------------------
----
get_html_translation_table
(PHP 4 >= 4.0b4)
get_html_translation_table -- Returns the translation table used by
htmlspecialchars() and htmlentities()
Description
string get_html_translation_table (int table [, int quote_style])
get_html_translation_table() will return the translation table that is used
internally for htmlspecialchars() and htmlentities(). There are two new
defines (HTML_ENTITIES, HTML_SPECIALCHARS) that allow you to specify the
table you want. And as in the htmlspecialchars() and htmlentities()
functions you can optionally specify the quote_style you are working with.
The default is ENT_COMPAT mode. See the description of these modes in
htmlspecialchars(). Example 1. Translation Table Example
$trans = get_html_translation_table (HTML_ENTITIES);
$str = "Hallo & <Frau> & Krämer";
$encoded = strtr ($str, $trans);
The $encoded variable will now contain: "Hallo & <Frau> &
Krämer".
The cool thing is using array_flip() to change the direction of the
translation.
$trans = array_flip ($trans);
$original = strtr ($str, $trans);
The content of $original would be: "Hallo & <Frau> & Krämer".
Note: This function was added in PHP 4.0.
See also: htmlspecialchars(), htmlentities(), strtr(), and array_flip().

I'm hoping somebody has the answer to this!
I have 3 pages, one a normal PHP page, and 2 which are classes.
One class, is a MySQL class I have written to connect/update users, etc
And the other is the manage users on the system.
Is there a way I can get the "users" class to talk to the "mysql" class?
I have this code to make a new instance of the MySQL class (the True means
use persistent connections) and a new instance of the users class
$db = new MySQL(True);
$users = new Users();
I am then using this code to check the list of banned users
$users->CheckBannedUser("spacetowns",$db);
In the CheckBannedUser function, I have this
$db->sql_query("SELECT user FROM banned_users");
But that does not work, (it works fine when used from the standard PHP page)
Is it not possible to do what I am trying to do?
Or am I doing it all wrong?
Many thanks,
Paul

Hello,
what I would do is build the instance of your mysql class in the constructor
of the user class
class User{
var $db;
// constructor
function User(){
$this->db = new Mysql(True);
}
// function that show how to use the Mysql class in the User class
function foo(){
$this->db->sql_query("SELECT user FROM banned_users");
}
} // end class
hope it help,
py

have a look at get_html_translation_table htmlspecialchars() ,
htmlentities() and get_html_translation_table.
these function do all the work for you without reinventing the wheel.

Just a blind shot:

Hi !
I have a site where I do the user autentication myself. (I auth
against a database). I want to be able to let a user logout, that is
when the user is logged out she/he should not be able to just
press the back button in the browser to get back or use a cached copy
of the login screen.
How do I do this ?
The Server is IIS and PHP is 4.0.6.

When they click logout, remove the marker from the database that specify
they are logged in.
Then you must on all pages see if this marker is either 'on' or 'off'. But
sessions would be better for this since it is one sql query less. Just
unregister the variable on logout and check with:
if (!session_is_registered('user_logged')) {
// Anything for non logged users, for example:
header('Location: login.php');
}
Being 'user_logged' the varibale name you will register when they logged
in.

That FAQ isnt totally right. With the new w32api extension you can do so but
its still very experimental so Id advise you either to write your own little

Hello,
I have a little question regarding regular expressions... I want to check
for the pattern
$num::
But, $num may not be started with another number (assume the number will be
51 , 1 will also match (the pattern 1:: is available in 51::) ... Currently,
my regular expression is:
eregi("([^0-9]$num::)", $string);
But that doesn't seem to work... The other option, the start of a line or a
: also didn't work:
eregi("([^|:]$sess_id::)", $string);
Anyone can help me with this?

There is an undocumented function in php4.0.6 that allows you

errors but also acts to log the work of the underlying
XSLT processor.
the function is xsl_set_error_handler and has parameters
of 1) the XSLT processor instance and 2) A string representing
the callback function name.
e.g. xslt_set_error_handler($this->xslth,"XSLT_ErrorHandler");
Here is a sample of the callback function i have. Using the
base php fuction error_log, you get the logging you want

function XSLT_ErrorHandler($parser, $code, $level, $errors) {

Hey everyone, I need some help with a variable issue. How can I delcare a variable and
then if a url variable of the same name is present use that value instead?
this is what I have:
if(!$dte)
{
$dte=date("j", time()+$ctime);
}
else
{
$dte=$dte;
}
and this causing an error in the 'if' expression.
Thanks!

The else clause can be removed, since it is not doing anything. What is the

I have one for you. I'm sure there is a simple solution, but I'm having

Let's say I have:

I doing wrong here?
Is there an equivalent to JavaScript's eval($commands) function?

What you're doing doesn't make any sense. If it were to work, it would look
like the following:
<?PHP <?PHP Query_Database( $category );?> ; ?>,
or something similar. I think what you want to do is:
<?php
$content = query_database($category);
echo $content;
?>
that's using psuedo-code, of course. You'll want to substitute correct php
syntax for returning database results.

I just asked a similar question yesterday. The answer is, conveniently
enough, eval().
One trick from the php.net page on the function is to do somehting like
this:
$content = "<?PHP Query_Database( $category );?>";
echo eval ("?>$content");

Kurt:
I understand where you are coming from, and I appreciate your answer.
However, I'm trying to get PHP to parse commands that are stored in a
variable because I'm passing those commands to a function. Inside the
function, it needs to evaluate the commands stored in the variable.
Does you solution solve that or does my description clarify my problem
better?

Okay there are two files involved here. First is my index.php file:
$params = array('class' => 'text10', 'content' => 'Query_Database( $category
)');
switch ( $mode ) {
case "list":
Make_TR( $params ); // This is executing the included function.
break;
default:
Display_Default();
}
Then there's the function that's located elsewhere in an include file:
<?PHP
function Make_TR ( $params ) {
( $params["class"] ) ? $class = "class=" . $params["class"] : $class = "";
( $params["content"] ) ? $content = $params["content"] : $content = "";

OK, maybe I'm missing something, but why not just replace:

with:

Assuming your Query_Database() function returns a string, this should
work fine.
