Hi all,
ok, this may be a dumb question, but I have a page that has server side
includes that include a php script like this :
<!--#include virtual="schedule.php" -->
works fine, except the script doesn't appear to receive any of the query
string information if that page has a query string on it...
an example would be something like this :
http://www.domain.com/index.shtml?myvariable=1
the php script should get $_REQUEST['myvariable']==1, but instead does not
get any of the query information.
The $_SERVER global gets the unescaped query string, but has no value for
just the query string...
any way around this without making the whole page a php script ?
Thanks,
Tim

um, huh? you mean it has the query string but it isn't parsed into the proper
superglobals ($_GET, $_REQUEST)? Not really sure what you're looking for here
so i'm going to just pretend this paragraph isn't here ;)

Yes, I mean that php gets the server information for the request, but it
doesn't get the QUERY_STRING variable. But it does get the
UNESCAPED_QUERY_STRING variable...wierd, huh ?
It might be that apache isn't sending that variable to php from an included
file...not sure...
That's why I'm asking everyone.

Yes that is exactly what it does .. sorry probably should have
explained it... but at least you read up the function :-)
the () tells preg to store the contents and they get numbered 1 2 3 ..
the \1 with a number below 10 tells it to use what it captured at that
point.
\D btw captures everything that is not a digit so you can use
that to cleanup the user input with $input = preg_replace('/\D/','',$input);

I always use ||
basically because to me it's easier to read in more complex statements ...
like this:
if ((($del_own == 1 && $post_userID == $userID) || $del_other == 1) &&
($postID != $first_postID || $del_thread == 1)) {
I always stick to the symbols ... just easier ...
|| && |! &!
^ being OR, AND, NOR, and NAND (believe NOR is actually called XOR, can't
remember ...)

I don't know of a class, but phpprojekt 4.1 has this functionality built

Hi all,
We just installed PHP 4.3.6 on FreeBSD 5.2.1 on some SMP machines and we are
experiencing some weird problems.
The PHP processes are running as FastCGI under Zeus with these compile
options:
./configure --with-curl \
--enable-sockets \
--enable-dbx \
--with-jpeg-dir \

The database backend is MySQL 4.0.18 and is run on a seperate dedicated
server.
Last night some problems occured - when we queried the databases for simple
queries that _should_ return some rows (and worked minutes before) the
database simply returned 0 rows. A restart og the mysqld and the php
processes solved the problems but they return at random.
I suspect that it is some weird problem with PHP / MySQL / SMP but I have no
clue what can cause the problem. The old servers we used before the upgrade
are all uni processor machines and we haven't experienced any similar
problems on those machines.
The sysctl for FreeBSD is set to: kern.ipc.shm_use_phys=1 (used on the old
setup as well)
Is there any issues with the mysql library under PHP that can cause the
problems on the server - eg. not thread safe?
I do hope that any of you have some pointers so I can get over this weird
problem.
Thanks in advance.
Regards

What mysqlclient is php linked to?
php -i | grep "Client API"
I would make sure you're using a 4.x version.

A couple things to check:
- the output of mysql_error(), it usually solves 90% of query
problems.
- if myismchk was ran on the table(s) mysql can get confused
about the indexes (until the table(s) are flushed)

hi...
i have to make an adult content censoring system so people cant post "bad"
words on any public viewable posts. i know preg_replace and possibaly
preg_match would be a huge help but im wondering how i would put all the bad
words in a file (textfile) 1 word on a line and have it look through the
file for the words? when it finds a match then it will either replace the
word with * but better yet tell the user that content in the post was
rejected because of bad content and take them back to the form with the
stuff they typed in it...
if there is a better way to do this (i hope sounds like a lot of work)....

The way I do it on a piece of forum software I wrote on a VERY popular
web site was as follows:
Create an include file which contains all your badwords in an array,
like:
$badword[] = 'well';
$badword[] = 'you';
$badword[] = 'get';
$badword[] = 'the';
$badword[] = 'idea';
Then I have a simple function as follows:
function APL_Func_BadWord ($text)
{
global $badwords;
// This will check our given text against the badword list. It
does it slightly differently
// in that instead of firing up the regular expression engine, we
use a more simple but just as effective technique:
// Get the length of the text
$original_length = strlen($text);
// Now strip out ANY of the "bad words" using the fast
str_replace and count the result
$stripped_length = strlen(str_replace($badwords, '',
strtolower($text)));
// In PHP5 we will use the str_ireplace function instead of
needing strtolower:
// $stripped_length = strlen(str_ireplace($badwords, '', $text));
// If the two lengths are different, the pos contained a badword
- simple as that!
if ($original_length <> $stripped_length)
{
return true;
}
else
{
return false;
}
}
and that's it - I pass any string I need to this whenever someone
posts a message, subject, etc etc and it hasn't failed me yet :)
(unless the bad word isn't in your list of course!)

To guard against 'lame' impressions of words to be filtered, you might also
check all combinations of variations of lettering of each undesired word.
You can do this programmatically without have to list them all.
i.e.
l replaced with digit 1 or any l looking characters with byte code > 128
o replace with digit 0 or any o looking characters with byte code > 128
f replaced with any f looking characters with byte code > 128

One advantage with using preg*, is you can have more flexible
matching instead of having a real large list of bad words:
$badword[] = '/suck(er|ing|ed)?/i';
Also instead of str_replace scanning the whole string 5 time to
replace the 5 items, its only scanned once, replacing up to five
things.
So depending on how large your list of words are and how large
the content is you scanning, preg_* might be a little more
efficient.
And then there is the possiblity that the users might get smart and
start entering things like:
s-u-c-k
One way to fix that is to replace all Non-word characters in the
subject string with null:
preg_replace('/\W/', '')
Of course that wont work if they use L337 or html tags.

My method *did* only scan the string once and str_replace is
definitely faster than preg_replace.
But I agree with the preg use for more complex word catching, but even
using that method you could spend ages building up a definitive
"badwords" array. I guess it depends how anal you want to be ;) (heh)

I was implying that internally php loops through each item in the
array you pass and calls str_replace on the items. Thats why I
added that it depends on the number of items and length of the
string your searching.
If you can take 50 element array down to 5, the overhead of preg
wont matter as much.

I am guessing not, but would like to be proved wrong.
I might get you wrong, but unless you take some precausions all scripts
on a single domain share common session id.

This is possible without problem. Just start your session in every script
and forward the session id from your frameset (which is probably the first
page to be called by the user) to each frame:
frames.inc
----------
<?
// start session here
// ...
<frameset cols="350,*" rows="*" frameborder="1">
<frame src="left.php?<?= SID; ?>" name="left" frameborder="1">
<frame src="main.php?<?= SID; ?>" name="main" frameborder="1">
</frameset>
?>
Make sure to put the session start code at the top of EVERY page.

No... PHP and JavaScript are executing at different time and

Are you trying to measure execution time of a query??
Look at:
http://www.php.net/microtime
No, I'm trying to get a little animation on the left frame to start when a query begins a pull (when the page begins to load) and then stop the animation when the page and data are fully loaded.
I suppose that the action is triggered by a link. Then you can put the
'start' javascript code in onclick event of that link. The 'stop' code
would go into onload event of the document body tag.
