Hi,
What shall one do to avoid people that trys to manipulate my server?
I mysql_real_escape_string() all input from GET and POST.
A long time ago I think I used addslashes or something like that too, so people
couldn't insert php code in their input. Is that still something I should do,
or does mysql_real_escape_string() take care of that too? And is it even
possible for a user to execute there own php code if I not output the input via
the eval() function?
When users input is displayed for others then themself I try to filter out html
tags too.
Anything else I should think of?
Sorry if this has been asked a million times before. Thanks for your time
/Regards Emil

I type cast all relevant variables before processing them as one last check.
Type casting forces the variable to be of the type you expect. For example,
if you are expecting two integers: $id1 and $id2 but you get the following
user input:
$_GET["id1"] = 1234;
$_GET["id2"] = "evil hakor code";
if you type cast these as:
$id1 = (int)$_GET["id1"];
$id2 = (int)$_GET["id2"];
the output of print "$id1, $id2" would be:
1234, 0
Possible types you can use (not all relevant to $_GET):
(int), (integer) - cast to integer
(bool), (boolean) - cast to boolean
(float), (double), (real) - cast to float
(string) - cast to string
(array) - cast to array
(object) - cast to object

I use the following as an include on all my form and cookie processing:
function stripFormSlashes($arr)
{
if (!is_array($arr))
{
return stripslashes($arr);
}
else
{
return array_map('stripFormSlashes', $arr);
}
}
if (get_magic_quotes_gpc())
{
$_GET = stripFormSlashes($_GET);
$_POST = stripFormSlashes($_POST);
}
If anyone see's a reason why I shouldn't, please clue me.

which data? It doesn't seem as if anyone knows what your trying to do.
(try to explain it again)
there is a difference between class and object - it's quite fundamental
to the whole OO concept.
<?
// the following is a [php4] class
class Test {
var $foo = "bar";
function getData() { return $this->foo; }
}
// $t is an object (assuming an error doesn't occur when instantiating it)
$t = new Test;
// this is an echo statement that outputs the return val from a method call
echo $t->getData(),"\n";
Any help, or pointers on what I am doing wrong is appreciated.

Basically what everyone else has said... they all work basically the

find Debian the best, I run screaming from anything that uses rpms.

I would consider the above to be the worst advice you could possibly
give someone starting out in Linux land. The easiest, nastiest and most
confusing way to screw up your linux install is to start manually
installing packages. I killed my first install and nearly my second
before I learnt my lesson.
Dependancy hell is the reason why package management systems exist, to
compile php5 on a fairly clean debian install I would need to install
roughly 130 packages, there is no way that I'm going to try to do that
by hand.
When one of my friends starts using linux I give tell them to never do a
manual install. You stick with the packages supplied or go with
unofficial packages like debian backports.
Compiling packages has it's place, many of my computers have a manually
compiled PHP, but it's definantly not something to do on a first date.
I also use the package manager to get all the dependancies (apt-get
build-dep php5) and all the related programs such as apache and postgres.

Yeah, i guess you're correct that this isn't very good advise. I
guess my point is more on the fact that you are limited on what
version of application you have available within the distros
package system.

Very much agreed.
Thanks for this pointing out, i guess my mindset wasn't focused on
a new user of linux.

Hello everybody,
I write here to find out if this is possible:
I want to expire an static file in the web browser through an HTTP
header (Expires, Cache-Control or something else) sent from a PHP
program. The usual thing is that those headers apply only to the
program or file sending those headers, what I want is that a program
sends those headers to affect a different file in the browser cache.
In more detail, My web app generates a JavaScript file from the
information stored in the database, that file represents the user menu
and it is what the user sees in the web browser. Now, through an apache
directive I set expiration times for several kinds of static resources
so the web server doesn't get slash dotted with lots of unnecessary
requests (this is a web app with lots of traffic).
Although the JavaScript files are generated from PHP, it is seen as
static content from the web browser POV. Right now I have set the
expiration time for the menu files to 20 minutes. But let's say an
admin user change the permissions of a user and the affected user hits a
link that says "Regenerate menu". What will happen is that the
JavaScript file will be regenerated on the web server but there is a
chance that the browser won't see the change because the file is still
valid in the cache.
I know I could reduce the expiration time to reduce this problem but
most of the time those files do not change. What can I do to notify the
web browser that the file in the cache is no longer valid?
I hope there is enough information here and that somebody can give me a
hint in the right direction.
Thanks,
-William

I don't think you can expire another file, I would consider any ability
to do so a bug in the browser. Someone with too much time on their
hands could possibly turn something like that into a security risk.
I would solve the changing javascript problem by subtly altering the
pages that use the javascript file. A web browser will recognise
menu.js, menu.js?ver=1 and menu.js?ver=2 as different pages. You can
use this for your application by including menu.js?ver=$ver in each of
your pages. When the menu is modified and regenerated, increment $ver.
Every client will refetch menu.js as it views it as a different file.

Nice idea... thanks.
I agree with you that the ability to expire another file would be
somewhat risky but I fail to see how this could be exploited. May be
the browser should allow this kind of operations from pages coming from
the same server. But again, I don't think this is posible to begin
with, I just wanted to make sure about that.
Thanks again,

Hi Barry,
I don't think this would work, this should refresh the HTML page only
but the link pointing to the javascript file will be taken from the
cache I think.

Hi Tedd,
That's not exactly what I am looking for. That would cause the
JavaScript file to be requested to the web server every single time. I
just want the browser to request the file only when it have been
modified on the server.
Let's say that by default, those JavaScript files expires every 4 hours
and that when a PHP program regenerates the file in the server it
should, somehow, notify the web browser that the file changed and that
it should request that file the next time it reloads the page or else
the user will be seeing an outdated menu.
I am almost sure this is not posible using HTTP headers. The only way I
see this could be achieved is by sending some random parameter to the JS
file so that the browser thinks it is a different file. This was
suggested by David Tulloh in a previous email.
Thanks again,
-William

The best way I've found to do this is to put the file modification time
in the querystring for the JS file. Set the expiry for that file to 365
days (or whatever) using Apache. That way you don't need to do anything
when you update the JS file for it to be rolled out and the only cost
per request is looking up the file modification time.
Another way to do it is to store the version number actually in the JS
filename itself. This would have the added benefit of being able to
quickly rollback to a previous version if needed.
Hope that helps.

I may not understand what you're trying to do -- but, perhaps using
something like:
<?php echo "Last modified: " . date ("F d Y H:i:s.", getlastmod());?>
In concert with what I suggested might work.

Depends on the workspace and what kind of work somone has to do.
Is it a monitoring position, or a leading one.
More infos would probably help though.

I am in need of some assistance working with classes. I have a function
(X) which calls a class (A), that class calls another class (B) and
returns the results. At this point I think I am doing everything
correctly within' class A because if I echo the results of Class A
calling Class B the data is displayed. However, when I use 'return
$data' from function X (ex. $data = $ClassA->function( $var1, $var2 );
) the word 'object' is being displayed in the browser.
Here is the code; any help, tips, pointers is appreciated.
// function 'chooser' calls class 'myAuth' and returns $data
function chooser( $level, $page, $user, $pass ) {
if( $page == "auth" ) {
require 'auth.inc.php';
$data = new myAuth;
$data = $data->login( $_POST['user'], $_POST['pass'] );
} else {
$data = "error";
}
return $data;
}
// myAuth class
class myAuth
{
var $data;
function login( $user, $pass ) {
if( ( empty( $user ) ) || ( empty( $pass ) ) ) {
$data = new myAuthTmplte();
$data = $data->AuthTemplate( 1, NULL, NULL, NULL, $errors );
} else {
$data = "error";
}
return $data; // If I do echo $data I can see the results of calling
the myAuthTmplte Class
}
// myAuthTmplte class
class myAuthTmplte
{
var $data;
function AuthTemplate( $cmd, $args, $num, $message, $errors ) {
$data = "I should be seeing this text right here"; // This data should
be displayed but I am only seeing the word 'object' in the browser
return $data;
}

I would like to have an optional pass-by-reference. i.e. you can call the
function w/o the variable. Basically, like how you don't need to pass
$matches to the preg_match function. I've tried, function some_func(&$var =
null) and this doesn't work. func_get_args only gets copies, does anyone
have any other solutions?

use php5. the following is from a method that has worked since php5beta3:
static function findRange(
$className,
$order = null,
$first = null,
$skip = null,
$f = null,
&$totalcount = null,
$trans = false,
$autocommit = false,
$minimal = false) { /**/ }

Hi,
My first mailing, if I'm in wrong group or such, let me know ;)
Here comes my question. I have implemented file uploads to my server. At the
end of upload, file is
beeing moved from /tmp to permanent directory. However, whenever this happens,
CPU goes berzerk and
waits for disk to finish moving file. As allowed files may be up to 100 MB per
file, having more
then 3 users makes complete server freeze. Meantime, server load reaches
skyhigh 40+. After file is
moved, server resumes normal operation, however while moving file server is
completely not
responding.
Is there a work around? I am not so good with linux (yet ^^), so I do not know
if there is place
for improvement on OS itself. I asked this question on Debian forum, but am
trying here as well.
If someone has same problem and prefferably solution, or even sugestions - all
is welcome! :)
Server P4 2.0
512 MB RAM (will be 2 GB by the end of the week)
2 x 80 GB IDE HDD
Thank you!
Regards,
Aleksandar

Are you sure its the move_uploaded_file() function that is causing the
delay? It could be the actual upload of the file itself. If it is the
function causing the delay than try the rename() function instead. Also, I
have used the copy() and unlink() functions and they work fast.

Hi there,
I just setted up some changes to the Apache configuration and made some
programming in PHP to log a request (and information about that request)
when it is taking a lot of time to finish (let's say > 20 secs). In the
logs, there have been lots of useful information and I already improved
the performance on several pages, specially related to database queries.
But from time to time there are pages in the log that shouldn't be slow
but still they take 20 or 30 secs to complete.
The strategy I used is the following:
1. Configure Apache to register the request time in the request headers
RequestHeader set requestTime %t
2. Create a function an register it with register_shutdown_function() so
it is executed after PHP ends the execution of every script.
3. This function will take the requestTime and calculate the difference
with the current time (time stamp).
4. If the difference (execution time) is less than 20 seconds it exits
normally, else, it logs the information about this request in a file.
5. The registered information includes: $_REQUEST data and $_SESSION
data at the time of execution. And finally a profile of some critical
functions. This functions are often the ones that goes to the database
and they are likely to be slow.
The page I am talking about doesn't execute any database query. It just
generates an image from the data that is stored in the session. I
however, profile some function that are not database queries but they
are the only "critical" path in the script.
Looking at the log I get the following information:
- Execution time: 29.3 secs
- Request started at: 11:08:06 AM
- Request ended at: 11:08:35 AM
- The functions that got executed were (time, class::method, duration):
- 11:08:06, GraficoMaterno::alturaUterina, 0.009499
- 11:08:06, GraficoAlturaUterina::session_start, 0.001259
- 11:08:06, GraficoAlturaUterina::session_write_close, 0.001613
- 11:08:06, GraficoAlturaUterina::sendImage, 0.029186
The last record in the profile (GraficoAlturaUterina::sendImage)
corresponds to the last couple of lines of code in the script which are:
imagepng($image);
imagedestroy($image);
As you can see they took only 0.029186 seconds which is very fast. the
other thing that you can see in the profile is that the last line of
code got executed exactly in the very same second in which the request
started. This means that the script is very fast and that something is
taking a lot of time after the last line of execution.
Note that I open and close the user session to update some data in a
safe manner that might be being accessed at the same time by other
apache processes. And as you can see it is very fast too... that was
the only suspect I had. :(
Finally, I don't think this is a problem of the function that logs the
execution time and that is executed automatically at shutdown. I was
seeing the sporadic slowdown even before implementing this
instrumentation and the function implementation is so simple that it is
very unlikely that the delay is in there.
For further information I am using PHP 4.3.11 and Apache 2, all of them
are official packages from a Fedora Core 3 system with the latest
updates. Is there a known bug in PHP that might be causing this
sporadic slowdowns? In general our web app is very fast but this are
the corner cases.
Any ideas about this?
Thanks in advance,
-William
