Hello,
My problem is this: I wish to have extremely highly secure sessions. I have
instituted full SSL, tuned apache, and set the web server security such that
there is very low possiblity of internal session hijacking. However, I am
concerned about the session fixation problem (as well as a direct attack on
the client box yielding the cookie contents), and would like to take into
consideration a user's browser SSL certificate as a fairly reliable
session-duration indicator that I am talking to the proper client throughout
the session. However I cannot find any environment variable or server
variable that suggests what the CLIENT's SSL information might be, only what
my server's certificates say. This is a fairly common recommendation on the
'net, and I must be a dunce but I cannot find out how to retrieve this
information in PHP. Could someone kindly point me in the direction of the
right variable here? Thanks!

Hello php-general,
how to display date like Monday, 1 January 1903 18:11 pm in php ?
(since the date() function only able to display date before 1970)
(and why it only support date after 1 Jan 1970) ?
thanks

Check out the manual:
http://www.php.net/strtotime
Theoretically, this should work:
$old_date = strtotime("January 1, 1903 18:11 pm");
echo date("Y-m-d H:i:s", $old_date);
But all that echoes is:
1969-12-31 18:59:59
On that manual page, you'll see the following note:
<quote>
Note: The valid range of a timestamp is typically from Fri, 13 Dec 1901
20:45:54 GMT to Tue, 19 Jan 2038 03:14:07 GMT. (These are the dates that
correspond to the minimum and maximum values for a 32-bit signed
integer.) Additionally, not all platforms support negative timestamps,
therefore your date range may be limited to no earlier than the Unix
epoch. This means that e.g. dates prior to Jan 1, 1970 will not work on
Windows, some Linux distributions, and a few other operating systems.
</quote>
I'm not sure whether there is a good work-around for converting that
string to a timestamp; however, this does work and will produce the
desired results:
$old_date = mktime(0, 11, 18, 1, 1, 1903);
echo date("Y-m-d H:i:s", $old_date);

Argh! I had the numbers reversed. It should be:
$old_date = mktime(18, 11, 0, 1, 1, 1903);
But you get the idea...

You probably need to eval() the strings after you extract them from the

Yeah, you're only using one browser, so you can only have one set of
cookies. To do this, you can't rely on cookies at all, which can be a
hassle. Otherwise, the session identifier will always be the most recent
one used, because that's what the cookie will reflect (unless you add some
logic to do otherwise).
I still think it might be better to approach this with programming logic.
As I said, this strategy will work, but it's ugly.

We're only talking about propagating the session identifier on the URL.
This has nothing to do with authentication and everything to do with
identification.

Yikes, that's a lot of misinformation in one sentence! Cookies are saved
locally, and they can make session identifier propagation seem transparent
for both the user and the developer. However, just as with URL data,
cookies are just something sent along in the request, so they're being
provided by the client. So, this information most definitely "gets out".
Sessions are not stored locally; they are stored on the server. It is very
important that you understand this, in fact, if you want to implement
secure session management. You should leverage this fact to strengthen
your mechanism.
Lastly, anyone can spoof this. The session identifier has to be provided
by the client, but a secure session mechanism will treat it with some
skepticism. Nothing from the client should ever be blindly trusted, which
is what I interpret "no one can spoof it" to be suggesting.
I have an article that elaborates much more on this topic that you can
read for free:

Hope that helps.

I think this is trickier than it sounds. Calling session_name with the
new name just prior to calling session_start should do it if you know
what name to set. But where are you going to get the name? If it is
hard-coded you are OK but if it is dynamic, as it has to be with user
logins, you need a place to store the session name -- and you can't use
sessions to do it! You end up having to pass at least something in the
URL, even if it is just a digit:
print("<a href=\"?$sessnum\" ...>");
the URL would be something like:
http://www.mydomain.com/page.php?1
from which you do something like:
session_name("PHPSESSID" . $_SERVER["QUERY_STRING"]);
session_start();
(obviously some error-checking might be beneficial as well).
I don't think you can do what you want with sessions alone. HTTP is
"too stateless" for that!

Chris,
ok, let me start over a little bit...
what I meant by the session data getting stored locally is that it is local
to the web server, not locally on the client browser. I understand how
session variables work. I just said local, and i was thinking
server...sorry about that...
what i meant by "no one can spoof it" is that no one knows what session
variables are stored with what data that is being used to authenticate that
session (ie additional digests to authenticate the request), and none of
those variables and values are set in a cookie or in URL's.
Nice article by the way, and I am indeed already using those same methods
to secure the user session. (I use SHA1 on the IP,PHPSESSIONID,user agent,
and a secret...)
So, it sounds like the only way for it to set a new cookie is by opening a
new browser app, which would allow you to send a new cookie different than
your other windows, and it doesn't look like I can do that from an existing
window, cause it will always send the same cookie...
darn...I guess I'll have to live with that...hmmmm...maybe I can set it on
a different cookie path...that might work...
anyways, thanks for the discussion chris.

I see. My apologies.
Perhaps we should both refrain from using locally and instead use server
and client to be clear. :-)

Yes, now that I see you're speaking about session data on the server, I
think the "no one can spoof it" is right. I hesitate to ever say such a
thing, only because I know it is too absolute to be true. But, session
data is very safe, I agree.

Thanks for the kind words. I must point out that you'll never see me
suggesting to use the IP address for anything important, especially
anything regarding security.
Also, George Schlossnagle recently expressed to me that he has observed
the User-Agent header changing for the same client. I've never heard of
this myself, and he had nothing but his memory of the event to support it,
but it's something to keep in mind. I try to never "punish" a user who
fails a check, just in case the user isn't actually the bad guy. Rather, I
ask the user to re-enter the password or something, which is less
problematic (unless the user really is a bad guy).

That's right. Recently, I think someone on this list was describing how a
particular version of IE behaves the exact way that you're wanting - it
kept cookies separate for each window. I've never seen or heard of this
being confirmed, but there's another rumor for you. :-)
> darn...I guess I'll have to live with that...hmmmm...maybe I can set it
> on a different cookie path...that might work...
Yes, there are many options for you if you write a bit of code. One option
would be to write your own session handler for the admin side of things,
using session_set_save_handler() to register your custom functions. Then,
you could do something as simple as appending "admin" to the session
identifier before storing and retrieving session data. This would be no
less secure than the standard mechanism, and it would allow you to have as
many sessions per user as you need.
> anyways, thanks for the discussion chris.
No problem. I hope this was more helpful.

Is this on a Unix box? The same box where the domain is hosted? If so
I think sendmail does that -- it notices the duplication, and only
sends the message once.

Ok someone told me the answer so I thought I would post it here for everyone
else.. basically it doesnąt work with words less than 4 characters, unless
you set a certain variable on startup to use less than 4 characters when
using fulltext searching.

Try putting the full path.
P.S.
Because it is harder to read.
Why is it bad?
Top posting.
What's a bad habit?
Can everyone quite top posting? And trim your posts? Does anyone need a list etiquette FAQ?

What is the request uri? Remember that include/require path is based on
the file requested by the browser, not on the path of the including file.

My data file is sth like:

2.196 2.178 2.424 2.291 2.225 2.213 2.386 2.19
........
I would like to get these data in order to plot graph.
I've tried to use fgets() and then convert them from string back into
array...but it seems doesn't work~
Thanks,

Hi,
Try using follow.
$sContents=file_get_contents("filename");
$sContents=split("",$sContents);
Ande then you will be able to use the values for plotting a graph.
Regards,
Umesh.
attached mail follows:
see php.net/file or php.net/fread
$file = "somefile.dat";
if (!fileexists($file)) return 0;
$filecontent = file($file);
$numbers = array();
if (is_array($filecontent) && count($filecontent)) {
foreach($filecontent as $line) {
// delete more than one space
$line = ereg_replace("[ ]*"," ", $line);
// explode whole line into array
$numbers_temp = explode(" ", $line);
// add temp arr to $numbers array
$numbers = array_merge($numbers, $numbers_temp);
}
}
and now you have all the data in $numbers array...
you DON'T need to convert strings to numbers.

why is var_dump( 0 == 'hello world') TRUE and not FALSE?

Hi,

because 0 is integer and the integer value of 'hello world' is 0 so
they are equal.

The same reason: intval('hello world') will equal 0.

Are you sure? I've not actually tried it but php.ini also has a default
Content-type which you CAN override using header().

Hey,
Not looking to reinvent the wheel.. I am looking for an inventory management
software package (written in PHP of course) that would be suitable for a

something that is easily modified/extensible. Any suggestions, Thanks in

Hi All,
I have searched for some references on pagination using mssql but have come
up empty.
I have looked at the tutorials on Zend and just about everywhere else but
unfortunately they all use LIMIT in the sql statement and the closest thing
to that in mssql is either TOP n, or SET ROWCOUNT which does me no good.
My thoughts were to bring in all the recordsets and parse through them line
by line to only show the ones that I want for the page that is displayed.
Part of my solution is below but I kekep getting this error;
Parse error: parse error, unexpected ')', expecting ';' in
D:\WWW\scriptgen\pagination_test.php on line 25
This is the code;
$limit = 10;
for ($i = 0; $i < $limit; $i++){ -- This is line 25
$name = mssql_result($i);
if($bgcolor == "#F2F7FF"){
$bgcolor = "#FFFFFF";
}
else{
$bgcolor = "#F2F7FF";
}
echo "<tr><td width=85% class=\"normal_text\"
bgcolor=\"$bgcolor\">$name</td></tr>\n";
}
Something wrong with my syntax?
