This means basically that the header files (*.h) where found but
none of the libraries were found.
You're compile path looks awkward to me.

How so? /usr/local/src/apache is simply a folder where I have all
apache related sources dumped and compiled prior to installation. So
naturally PHP's source becomes /usr/local/src/apache/php-5.0.5
what does your ./configure line look like?
This same configure line compiles PHP4.4.1 just fine. It's long:

your questions are on point...
if you're going to really talk about doing transactions... it appears to me
that you really need to solve this. www.passmarksecurity.com claims to have
solved this.. although i'm not sure i agree with them.. for one, i can't
find a thorough independent analysis, for two, from what i can tell... they
rely on the server app getting information from the browser. their approach
appears to depend on their belief that the intermediary (fake) app can't be
in the middle, therefore they'll only get valid information from the 'real'
browser...
as far as i can tell, their solution is to look at certain information (mac
address/headers/etc...) that they're inclined to believe can't be
altered/spoofed. i'm not buying it!!!!
as far as i can tell... you essentially need multiple information streams on
the client(browser) machine coming from the server... in actuality, i can
envision the following...
master server <----> customer client
/ \
/ \
biz server <---> customer browser
the customer and the biz server talk to each other
the customer client and master server talk to each other
the customer client and browser are on the same machine
the idea would be for the client app to be abel to 'get/see' the url that
the biz server app is sending for return requests. the client app would then
go back to the master server to 'determine' if the url/ip address is corect
for the given site. this can be accomplished fairly quickly by polling
random dns servers at the master level.
if the majority of the polled dns servers return the same address as the one
from the biz server, we can assume that the biz server is giving the correct
url/ip addresses.. this could be done for every request.
this kind of approach would be pretty difficult to corrupt, unless the
client app where somehow mangled/forged. you could determine if the client
was ever screwed with by using an SMS type of system via the cell phone...

Subject: RE: [PHP] security question... "man in the middle attacks"
'man in the middle' relates to any interception/redirection and I see I was
looking at it more as a hacker posing as the user interacting with a
legitmate site rather than the user interacting with a bogus site. Two
sides to a similar coin.
real site <----> bogus user - bogus site <-----> real user
the session ID issue I was talking about helps prevent a bogus user from
posing as a legitimate one because only the real-site and the real-user
should know the session ID being used but then again, it could be
intercepted. I think there's more to it than I'm explaining, but it's not
coming to me right now. My apologies for not being more specific.
Definitely check out Chris Shiflett's site: http://shiflett.org/ (I got
un-lazy for a moment to look it up).. he might have something in there
somewhere.
I think what you're talking about is going to be kind of tricky because more
so than other security issues, this issue seems more susceptible to
measure/countermeasure type things. You could use a secure connection, but
what happens if the hacker gets a certificate for their bogus site? What
happens if they mask the URL so it appears to be coming from the legitmate
site?
I'm wondering how often the scenario you're talking about will come into
play though. Seems that unless someone hacks your site and puts in some
bogus URLs that drag your legit users away from your legit site, the only
way someone's going to get lured into this situation is if someone is
posting bogus URLs somewhere else.. like on online forums or something
saying "Come see Bruce's website!" and going to a totally different URL
posing as yours. In which case you can really only rely on your user's
intelligence to NOT fall for it.
Anyway, just some things to ponder while you find a "real" answer. :) I
have some experience with security issues, but wouldn't necessarily call
myself an 'expert'. Working on it though.

i'm not sure i see how this would affect a man in the middle attack...
a man in the middle attack, for the purpose of this thread is the insertion
of a clone/fake web app between the user's browaser and the original web
site...
i'm looking for ways/solutions that will prevent a fake/clone site from
redirecting the user, or intercepting the user/initial site traffic...
original fake user
site <-------> site <---------> browser
in this case a fake site could look like the original site, intercepting the
communication between the original/user. how can it be detected, can it
really be prevented?
as far as i can tell, what ever the original might send to the user's
browser, can simply be intercepted by the fake site, and in turn sent to the
user, where the response from the user can be sent/spoofed to the
original...
so, if you're a security guru, or really understand the nuances here.. let's
here your information.
thanks

Subject: Re: [PHP] security question... "man in the middle attacks"
You'll probably get some good responses, especially if Chris Schifflet (sp?)
pipes up. But one technique I've seen to prevent man in the middle type
attacks is to make copious use of session ID's. That is, a session, when
it's created, generates a unique ID. When this ID is created, a lot of
systems will store a copy in a database then periodically query the user to
see what session ID they have and compare the two. There may be ways to
still intercept this or forge the session ID, but it's a start. Just
thought I'd mention it in case it helps your web searches at all.
I look forward to hearing the responses your quest generates. Thanks for
posting!

hey...
anybody here have a serious background in security, or with 'man in the
middle attacks'???
in particular, i'm trying to get my hands around ways of preventing a
server/browser app to be susceptible to a 'man in the middle attack'
serious pointers would be helpful. searching across google hasn't turned up
any examples of how this can be accomplished...

He got "Cookie NOT set." which means exactly what it says. He's using

cookies from this domain. I can't verify that he's set it correctly,
but he has been told twice how to do it. I also know his browser must
be saving some cookies, as he is able to login to other sites. Has
anyone run into other sources of cookie-blockage in the past? I
cannot manage to duplicate this when I have IE set to always allow
cookies from this domain.
Thanks for any tips,

Request from MY browser? I get
array(2) { ["sessioncookie"]=> string(1) "1" ["storedcookie"]=>
string(1) "1" }
This isn't a problem in my browser, however. I don't want to keep
sending this customer to random scripts, so can you explain the point of
this script? I mean, in what way might this help me figure out why his
browser is not setting a cookie?

But I sure would like to see the URL once he has clicked it. Have you tried

there is likely to be a clue.
On privacy policies in IE (can he try another browser?) what is his setting?
I'm still waiting on definitive word as to what exactly his privacy
settings are. In my experiments, manually setting IE to "Always Allow"
or "Always Block" cookies for a domain will completely override privacy
settings. I've had IE privacy set to allow no cookies, and manually
added the domain to "Always Allow" and this overrode the no cookies setting.
For kicks and giggles, I changed $_REQUEST to $_GET, but he reported no
difference. Again, I don't see this as being the problem, since if it
were so, he'd get no output at all instead of "Cookie NOT set." I'm
quite convinced this is a matter of his cookie simply not being set. He
is not able to ever see a cookie for this domain in his temp internet
files folder, though he tells us there are other cookies there.
I wish I could tell him to just use another friggin browser, but it
would be nice to fix it so he can use the one he wants, no matter what
words one can say about his choice. ;)
I have not looked into it, but do some internet security apps like
Norton try to block certain cookies? I've not come across this, as I
don't really use those programs, but right now I'm grasping for straws.

Certain anti-virus/spyware programs can and do block cookies and can be very

Yes they do - I replied to your original message to this mailing list
saying exactly that. I will copy it again:
"What about third party software? Norton for example has cookie
features that will totally over-ride any IE setting with regards to
blocking them, etc. It's not the only one."
Ok, so not much detail - but you get the drift!

I think you can walk the array returned by glob and create a hash :
$arr=glob(..);
foreach($arr as $file){
$stat=stat($file);
$mtime=$stat[mtime];
$new[$file]=$mtime;
}
Now you should have array like this :
foo.txt => 19879823
foo1.txt => 1987987998
Now you can use array_sort function to sort the new array.
Good luck.

foreach($arr as $file){
// you can also write this like so, sometimes useful for keeping code
compact and minimizing variable usage:
foreach(glob(/* bla bla */) as $file) {
$stat=stat($file);
$mtime=$stat[mtime];
// don't forget to use quotes!:
$mtime=$stat['mtime'];
$new[$file]=$mtime;
}
Now you should have array like this :
foo.txt => 19879823
foo1.txt => 1987987998
Now you can use array_sort function to sort the new array.
array_multi_sort() is a slightly different way of doing the same thing,
sometimes handy when you need to be able to switch between different
sort orders:
$mFilesFound = glob(/* bla bla */);
foreach ($mFilesFound as $file) {
$mTimes[] = filemtime($file);
}
array_multisort($mTimes, SORT_DESC, $mFilesFound);
Good luck.

Does anyone know of an open source or commercial php library for parsing

I can't find anything on the usual php script sites.
Unless I'm missing something, this seems to be a gap - in the Java world
there is a wide choice of native solutions.

Sounds as though, like me, you might just get away with a decision table
parser rather than a fully-fledged corporate rules engine. though your
application is a bit more complex than ours.
It's surprising to me that we are faced with rolling our own or working
with Java - suggests that PHP still has a bit to go as a platform for
serious business systems.

Are you planning to have PHP run as a servelet within JBoss? Does this
work reliably? I much prefer to keep things as simple as possible.
As an alternative, I worked briefly on a native PHP Petri-net workflow
engine with a guy called Tony Marston before we parted ways. He has
written it up here:

The lack of a decision table/business rule parser does not suggest that PHP
has a way to go as a platform for serious business, as many serious
businesses will attest to. What it does suggest is that no one has had the
need or opportunity to construct one in PHP.

I wrote to Tony a couple of months ago and he said that his workflow code might
be available someday, but wasn't available currently. His ideas are published
on his website, but only code snippets.

For

use
call_user_func(array($className,'doSomething'),$args[0],$args[1]);
or
call_user_func_array(array($className,'doSomething'),$args);

how can i call static methods of a class whose name is variable.. something like
<? $className::doSomething(); // throws a parser error ?>
I can do this with reflection by creating a ReflectionMethod object
then invoke()ing it, but is there a better way?
try call_user_func() and/or call_user_func_array()
e.g.
call_user_func( array($className, 'doSomething') );
the array passed in this case is how one tells php the callback
function you are handing it is a class+method, you can also use this
callback notation to pass in an object+method.
Thanks

I'm attempting to read a list of files in a directory using readdir()
but am having problems with mpeg files not seemingly being read.
Cope snippet:
$count = 0;
while (false !== ($file = readdir($open_dir)))
{
if ($file != '.' && $file != '..')
{
if (file_exists("$VID_DIR/$file"))
{
$count++;
$count counts any 'avi' files but not 'mpg' files.
Any suggestions much apreciated.

Without seeing the rest of the code I am going to assume that $open_dir is
the handle for the directory the files are in. Given that, why would you
specify a directory in your file_exists function? I am unsure why
file_exists would be necessary at this point. Eliminate that condition and
see what the results are

Yes $open_dir is the handle from opendir().
The file_exists is simply checking for an associated file elsewhere as
I'm looking for video files and thumbnails.
As I said, this works fine for avi suffixed files but not mpg or mpeg
suffixed files.

Make sure to always hit reply-all, or the e-mail will not go back to the
list.
If file exists is looking for an associated files is it probable that the
.mpg files do not have one associated with it in the other directory?

It is probable, that's why the check is there, but in this case the
associated file(s) definitely does exist. If I simply change the file
extensions from mpg to avi the script works.

Graham,
Is safe mode enabled in your config file? If safe mode is on, PHP will
check the file to ensure it is owned by the same user executing the
script. If this condition fails, file_exists() will not work on the file.
http://php.net/file_exists
http://php.net/manual/en/features.safe-mode.php
Cheers,

Try this simple example and see what is output...
if ($handle = opendir('/path/to/files')) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {
echo "$file\n";
}
}
closedir($handle);
}

OK, of course it's my fault !! :o
My directory variables are using relative paths and I was trying to
access the parent directory from the sub-directory but not using '..'
Sorry.....
Thanks for your help.

Hello all,
The following script returns 'search failed...' after 'LDAP bind
successful...'.
==
<?php
$ldaprdn = "CN=John Smith,OU=Users,DC=Coll,DC=some,DC=edu";
$ldappass = "passwd";
$ds=ldap_connect("ad.coll.some.edu");
if ($ds) {
echo "Binding ...<br />";
$r=ldap_bind($ds, $ldaprdn, $ldappass);
if ($r) {
echo "LDAP bind successful...<br />";
} else {
echo "LDAP bind failed...<br />";
exit;

$filter = "(sAMAccountName=jsmith)";
$base = "DC=Coll,DC=some,DC=edu";
$sr=ldap_search($ds, $base, $filter);
if ($sr)
{
echo "Search result is " . $sr . "<br />";
} else {
echo "search failed...<br />";
}
}
?>

However, the following ldapsearch returns the result fine.
% ldapsearch -h ad.coll.some.edu -s sub -b "dc=coll,dc=some,dc=edu" -x
-D 'CN=John Smith,OU=Users,DC=Coll,DC=some,DC=edu' -W
"samaccountname=jsmith"
I'm in dark now and don't know where to look for more information on why
ldap_search did not work. I'd appreciate any help.

I've figured out. Adding 'ldap_set_option($ds,
LDAP_OPT_PROTOCOL_VERSION, 3);' right after ldap_connect fixed the problem.

Thank you for the time and effort of explaining this. It sounds
fascinating, and worthy of investigating.
I will spend some time looking into this.
Thanks again.

Personally, I would start creation of PHP framework by cleaning up PHP
sytax. It's freakin' impossible to make complex OOP clean:
there is plenty wrong with php, but none of your comments are
even vaguely relevant.
btw you can 'clean up the syntax' - just don't expect it
to ever make it into the official build.
$this->output(array('dir', 'template'), &new BlaBla($this->bla));
this is supposed to prove what exactly? apart from the fact that OO in
php is not something you are very familiar with, for starters if you
want to do OO in php these days you should be using php5 (assuming you
don't have a mountain of existing php4 OO code you have to work with -
if you do then moaning about syntax is completely pointless... php4 is
is 'bugfix only')
the '&' sign for passing objects around in php5 is unnecessary because objects
are always passed around as references. and if you really know that you
need a reference to a reference you skill level should at the very least
be such that 'freakin' impossible' is not relevant at all.

If I'm understanding what you want, consider this. I use it to check matching
tags.
First get an array of all the start tags:
$pattern= "%<([^/][a-z_\-]*)>%i"; //all start tags used <xxx>
preg_match_all("$pattern", $text_str, $matches);
$start_tags= $matches[1];
$start_tag_nums= array_count_values($start_tags); //get count for each tag
Then do the same for your end tags, using the same pattern but with the end tag
slash. </....
Finally, you make a text list of the mismatches:
foreach($start_tag_nums as $tag=> $num){
if($num != $end_tag_nums[$tag]) $end_error_msg .= "<$tag> || ";
}//end foreach
echo $end_error_msg;

I installed all packages with SUSE 10.0 YaST rpms. I installed earlier
versions on SuSE 9.1 from rpms with no problems. After install I changed
mysql to run as user mysql. add root and damon to the group mysql. SuSe has
added stems in the install that (When I start the mysql server) that change
the my sql permisions.
I recently uninstall php5 and went back to php4. The .so files are now
installed but I get a message now that access is denied when I try using my
browser running as root:
http://localhost/phpMyAdmin/.
I've configured php.ini and config.inc.php correctly I think. I can manually
get to mysql from the command line as root with no problem. I'm almost
certain its a permissions problem but I'm not sure where.
/srv/www/htdocs
drwxr-xr-x 6 root root 3000 2005-11-21 17:25 phpMyAdmin
/srv/www/htdocs/phpMyAdmin
-rw-rw-r-- 1 root root 38826 2005-11-21 17:25 config.inc.php
I can either reinstall php5 or stay with php4 as long as I get this working.
You help will be greatly appreciated.
Thanks
Russ
