There was a posting on http://us3.php.net/dl dated July 18th regarding the
dl exploit problem. Following the advice in the posting, my shared hosting
service disabled dl on our hosting server. I can't load my custom PHP
extension anymore.
I am wondering if anyone knows about any active development effort to fix
this problem. Please let me know.
Thank you very much.
P.S.
Text of the posting on PHP documentation page for dl:
WARNING: enable_dl/dl()
*********************
There is an exploit circulating currently which takes advantage of dl() to
inject code into Apache which causes all requests to all virtual hosts to be
redirected to a page of the attackers choice.
All operators of shared web hosting servers with Apache and PHP should
disable dl() by setting enable_dl to off otherwise your servers are
vulnerable to this exploit.
This exploit is generally known as flame.so (the object that is loaded into
Apache) and flame.php (the php script that loads it).

The reason why is because there's no real long support in PHP.
But, since you mention a value such as 0.01, you are not looking for a
long, you are looking for a float. So, what you need to do is to
type-cast all the values involved in the making of the variable that
holds the float value.
For instance:
$var = (float)$var1 / (float)$var2;
$query = sprintf('%.2f %s', (float)$var, $string);
I haven't found the exact points where PHP forgets it's a float, but
it's always good to make sure all mathematical operations are performed
on the value as a float by type-casting, otherwise it might lose
information.

Thanks,
the problem with cut an paste i have not only one of these messages
i get huge amounts of these. So i stripped down to one, sorry my fault.
a) usally 4-6
b) no
c) yes, as I mentioned i tried both (old/new)
d) never tested i jump over 5.0
the problem with the code is currently the problem only occures in the
real application which as about 20000 lines of code. I tried to
stripped down
but there was not success. So I ask about how could i work out an idea
from the php source to find these problem. I'am pretty sure that i done
everything rightly in my application code. It works perfectly with
the old-style and php 4.x
and i converted all to the new style which is easy of course it is
generated
php source code so there is not really a general fault possible. If the
generator works-:)
your questions aren't silly

any given class will never have a variable number of parents ;-)

5.1 is still beta - test it on 5.0 (consider that the mailing list equivelant
of a military order ;-)
does the problem occur in only 1 baseclass? or in a fixed number of
baseclasses? or is does it occur anywhere/everywhere.
are you trying to reassign $this or are you using the reference token (&)
when passing objects around? (I ask because you seem to indicate that the
codebase is being moved from php4 where such things are almost required to
make usuable OO code - whereas in php5 it's asking for trouble)
pump up error_reporting to full i.e. error_reporting( E_ALL | E_STRICT )
- maybe it will give you a hint.
also you might consider placing a call to debug_print_backtrace() in each
and every constructor to help see wtf is going on.
lastly get a copy of Zend Studio Client/Server and set it up so that you
can do step by step debugging to see _exactly_ what is going on.
I'm running out of ideas here ... I can only suggest now to post code
- and plenty of it - if that is possible, send a link to somewhere rather than
bombard everyone on the list with 1000's of lines of code.

there are is alot of code which works as i mentioned all the code
is generated. The pattern of the working code is not different to the
none working. Also i have some examples where i call the same class
in other scripts and they are working. So there is no write error. Also
the old syntax should work without change and php 4 it works perfect.

i will work to strip down you can't run the code without 20 own

its worth it - regardless of whether it works properly on 5.0 or not
it strengthens any eventual bug report you may make - i.e. you can indicate
in depth problem research.
also try a fresh build of the latest php5.1 beta - just in case.
no hurry on my account, I'm just an interested bystander :-)

it may help you to see a pattern that is not obvious by viewing the stack trace

<ring ring> (alarm bell goes off) - you have 20+ of your own extensions that
are required, there is a distinct possibility that the problem lies within them ...
recompling php with all the debug configure options turned on
and using valgrind and/or gdb to debug maybe what you need to be doing.
Side Note: you have code generators and a bunch of custom extensions - it sounds
interesting to say the least! I'd love to see your stuff ... will you be going open
source with it per chance? (maybe that is not even a decision you are allowed to make)

LONG Done, standard procedure, the extentions working all without
change from 4.x.
Our extentions only doing some weired algorithmens on integer and
float matrixes which
are too slow in native php. They do not allocated memory only on the
stack-:). All around
it is pretty simple stuff.

it is for you just useless stuff the application is the rapid
development enviroment for a
real huge a datamining application which is mostly design by the use
of MDA(Model Driven Architecture).
We use php for this to safe the huge compile times we need to have on
the also generated
c++ application. PHP is only used for testing and and safe turnaround
times-:) but without the
backend databases which believe me are unsharable-:) you gets out of
the code nothing.

Hi all. This has been an interesting week.
Now the form works, and I am able to error check, if no errors look into
user answer table and delete from that all q_ids matching the ones just
picked, insert this page of question/answer info (q_id/a_id) into the
user answer db, and if successful advance the category by 1 and get more
questions. It works.
I must have a logic error though because for some reason even though I
say to delete matching q_ids and reinsert, then move on, if the user
hits the back button, changes answers and hits submit again, the table
does not update . . . and the category does not increment. We get stuck
on this page of questions/answers forever.
What DOES happen after BACK is that the answers they select get passed
back to error check (eg if they select a select box to nothing, error
checking reenters its value into $message) and those values get passed
back to the display page (eg $_POST[$qname] == $aid) because the
"selected" answers change. It's just the db call and category advance
which get stuck.
Any help will be greatly appreciated - Here's the code:
<?php

session_start();

Do you want to allow people to go back and chnage things ?
If so, write a suitable UPDATE statement
Sample UPDATE syntax
UPDATE table
SET field=1
WHERE field2='x'
You will probably want to check whether the answers already exist, use a
select statement for this. Unsure if this works in mysql, but
IF NOT EXISTS
(select id from table where field=1)
UPDATE table
SET field=1
WHERE field2='x'
might do the trick, or something similar will at any rate.
If you want to stop people going back, check the referer (sic)

Thanks, but I think the update function should be built in -- the sql
checks whether the userAnswer table contains the q_id the user has just
entered; if so, it deletes the row containing it and then the second
query inserts the new values.
$qidlist_sql="DELETE FROM teresa WHERE q_id IN (" .
(implode(",",$qidlist)) . ");"
$q_a_sql="INSERT INTO teresa (u_id, q_id, a_id )
VALUES " . (implode(",",$qanda)) . ";";
I think there's something wrong with the logic of how I'm handling
$_POST info and passing it back and forth: here's why: if I close the
browser and reopen it and refill the same questions, the answer table
shows the updated answers. there's something in the logic I am using
about how I am advancing the $cat and managing the $_POST information. I
think . But I cannot find it.
Anyone?

The code below isn't much help to debug. Do some checking to figure out
how far into your IF statement you're getting. Is the query running?
Is it the query you expect? (Step #1 when inserting or creating dynamic
queries that aren't working: print them out to make sure they are what
you think they are.) Is the category being incremented? You say you
can go back, but you can't go forward. Look at the page source, is the
form action what it should be? Look at the form hidden variables (if
any) are they what you expect?

Yes it runs successfully

Yes it is perfect, and provided this is a new session and we're going
forward page by page, it properly deletes from and inserts to the db as
expected
(Step #1 when inserting or creating dynamic
> queries that aren't working: print them out to make sure they are what

Yes, absolutely

Actually no. In a new session, I can start and go forward page by page
to the end of the questionnaire, advancing each stage perfectly, storing
all values exactly as I'd expect.
The trouble starts if, during the process, the user hits the BACK
button. At that point, user can reload the last page of questions,
displaying the answers they gave. If the user makes changes, those
changes get error checked but do not become part of the sql query. Also,
user can not move forwards any more. So it's as the subject says -
everything works...until they hit the back button, from which point the
whole thing goes gablooey.
Look at the page source, is the
> form action what it should be?
Yes
Look at the form hidden variables (if
> any) are they what you expect?
No. $cat remains what it was BEFORE the user hit the BACK button.
However the questions dispayed are from the $cat which is in fact $cat-1

Surely it would be much simpler to just use have javascript to set a
placed image to a new (or the same) location - this image is then
generated by JPGraph et al with no modification to code. I have been
using this technique for years to make server calls without page
refreshing. (Well, that or an invisible frame/iframe/layer)

Just looked into this recently and here's a brief rundown of what I've found:
1. If you run PHP on a non-Windows system, your only option seems to be making a connection to a remote ODBC data source (hosted on a Windows machine presumably). There was something..err.. ODBTP (?) that would work on linux to connect to remote ODBC connections
If you run PHP on a Windows server, then you have the following options:
2. ODBC connection via DSN
3. DSNLess connection (you can do this with a DB abstraction layer like ADODB)
4. COM connection (requires Access be installed on the server and, in my opinion, is the worst solution out of the group due to it's resource use)
There doesn't appear to be a good direct way to read Access files on a linux machine. I may have come across a commercial Access driver ($$$) for linux, but can't remember. If I did, I would have dismissed it fairly quickly as 'free' is more my budget right now :)
If you need links to the stuff above, let me know and I'll try to dig up some. I also have a script I wrote using WinBinder and ADODB on a Windows box to hit an Access database, pull data, scrub it, then insert it into a MySQL database via ODBC.

I've run into a situation where PHP is way off when doing a relatively
simple calculation of distance between two points in 2-dimensional space,
where coordinates go from 1 to 300 in both X and Y directions. When passing
300, it goes back to 1, and vise-versa (it's for a game and is supposed to
approximate the movement over a sphere).
Using this function:
function calc_distance($curX,$curY,$newX,$newY) {
// calculate distance to new location
$distX = abs($curX - $newX);
$distY = abs($curY - $newY);
if ($distX <= 150 && $distY <= 150) {
$dist = sqrt($distX^2 + $distY^2);
} elseif ($distX > 150 && $distY <= 150) {
$dist = sqrt((abs(300 - $newX))^2 + $distY^2);
} elseif ($distX <= 150 && $distY > 150) {
$dist = sqrt($distX^2 + (abs(300 - $newY))^2);
} else {
$dist = sqrt((abs(300 - $newX))^2 + (abs(300 - $newY))^2);
}
return $dist;
}
And using 150,150 as $curX,$curY and 300,300 as $newX,$newY ... PHP
calculates $dist as 3.46410161514
which obviously is far off target ...referring to my calcultor, the correct
result for the same code is supposed to be 212.1320
What happens here ? And how the heck do I get to calculate right ?
Float errors usually isn't this severe, so I'm assuming it's a problem with
properly acknowledging the hierarchi of the mathematical operators ...
It's PHP ver. 4.3.0, on Apache/2.0.53 (Win32), on WinXP SP1
I've been trying to manually calculate the formula out of order to figure
out how the strange result comes about, but haven't had any success yet ...
Any suggestions ?

Though I will agree with you to some extent, I've had quite a lot of
success with this, which is pretty thorough:
^(?:[\w\!\#\$\%\&\'\*\+\-\/\=\?\^\`\{\|\}\~]+\.)*[\w\!\#\$\%\&\'\*\+\-
\/\=\?\^\`\{\|\}\~]+(?:(?:(?:[a-zA-Z0-9](?:[a-zA-Z0-9\-](?!\.)){0,61}
[a-zA-Z0-9]?\.)+[a-zA-Z0-9](?:[a-zA-Z0-9\-](?!$)){0,61}[a-zA-Z0-9]?)|
(?:\[(?:(?:[01]?\d{1,2}|2[0-4]\d|25[0-5])\.){3}(?:[01]?\d{1,2}|2[0-4]
\d|25[0-5])\]))$

Hi,
I've want to dig a bit deeper into regular expressions for php.
I wonder if anyone can help me choosing between 2 books I'm considering buying:
1. Open Source Regular Expression Recipes - Nathan A Good
2. Mastering Regular Expressions - Jeffrey Freidl
If your using/reading one of these books, please let me know which one
is best for PHP regex.
Thnx

Dear you,
So, if I need to define a set of varibles ( two dimension array, eg :
$func[0,0] ) and via the varibles of form tag ( format, eg :
$_GET["varname"] or $_POST["varname"] ), how about the example sources ?
Thank for your help !
Edward.

<?php
for ($x=0;$x<10;$x++){
$func[$x]=$x;
}
print_r($func);
?>
This uses an array, so, in this case, your variables would be referenced as
$func[0]..$func[9].

Just for the sake of example let's say i keep track of all of a customers previous orders in a
table like this:
Last_Order
------
Cust_ID
Item_No
No_ordered
When a customer places an order i put the order details in an a table like this:
Orders
-----------
Order_ID
Cust_ID
Item_No
No_ordered
Let's say when my customer returns he decides he wants everything he ordered previously plus some
other stuff. Assuming this customer has unique customer ID of 345 and his current new order id is
678. Can i copy his last order into the orders table with just a SQL statement like:
INSERT INTO Orders VALUES ('678',(SELECT * FROM Last_Order WHERE Cust_ID = '678'))
What i want to do is grab all the data from Last_Order associated with cust_id 345 (or whatever)
and insert it into the Orders table with a Order_ID in this case 678. Let me know if this isn’t
clear. This SQL obviously doesn't work, however, my question is there a way to do this with SQL
alone? Or do i need to grab all the records from the Last_Order table loop through the record set
and insert each new row into Orders individually?
-k.

Is $results coming from a db? Select only the rows which do not have a
value of 0.

foreach($results as $key => $value)
{
if ($value == 0) continue;
echo $key.': '. $value .'<br>';

Yes, it comes fro DB, but, quesry is alerady "to complex" (for me :))
with union, joint, ... and expanding with something else ill take
additional few hours to figure it out.
And, Stut's and Chris' "continue" solution sound perfect for me :)
Thanks guys on such a fast respond!

Yeah, I thought about that. But to be honest, I don't know how to
recompile with builds from the CD/rpms. This is the first time I've ever
done it this way. So if I get the latest RPM and install it it should
activate session right? And then I just need to restart apache2 and I
should be good?
