You could make your PC think www.foo.com is local. Open up your hosts
file (typically /etch/hosts on *nix,
c:\windows\system32\drivers\etc\hosts on Windows) and add a line that reads:
127.0.0.1 www.foo.com
That way your PC (only your PC) will think that www.foo.com is local,
and not go over the Interweb for it.

Subject: [PHP] Re: SESSION Array problem - possibly different PHP versions?
Put a print_r($_SESSION) at the top and bottom of your page code so you can
see
what's happening.
Also check your code that updates the session assignment by the GET value.
It
appears your code maybe unset()ing the session assignments.
Are you using Cookies? If so, check this code carefully as it can cause non
obvious things depending on whether the client machine has cookies enabled
or
disabled.
---------------------
Thanks will do so going to check the unset() as well as the print_r at top
and bottom, also I am not using cookies hope to get this sucker working.
Will keep you posted.

I should say that running 7 quueries against 200MB table with ~600 000 rows
for 4 seconds looks to me as if there was no indexes and very poor database
design (i mean that CVS file is dumped into database incorrectly). Or you'r
server is Pentium 100 :)
P.S. Having myself a 1.5GB database with some tables 300MB+, having 1070

If you do go the MySQL route, MySQL can import CSV files natively, and
it'll be a lot faster than doing it through PHP. Just look up the
syntax for the LOAD DATA INFILE command... or look here.
http://dev.mysql.com/doc/refman/5.1/en/load-data.html
Here's an example:
LOAD DATA LOCAL INFILE '/importfile.csv'
INTO TABLE test_table
FIELDS TERMINATED BY ','
LINES TERMINATED BY '\n'
(field1, filed2, field3);
I've had to do imports of a million or more records from CSV files, and
PHP is a lot slower than MySQL at importing them :)

Not this thread again :) Search the archives for this one. There have
been numerous discussions about this topic. Personally i don't see
what would make this technique more professional. It's just a matter
of taste.

Well, bearing in mind I only have experience of MySQL, the general
consensus is to save it to a file on you hard drive and store the file
name in the database. If for whatever reason you can't or don't want to
do that, then at least store it in a separate table that only gets
touched when the image is requested.

It's not so sensitive :) It's just one of those questions that pop''s
up a lot. And some of those discussions were pretty heated.

It's a webmaster forum, but a little.... err, shall we say,
"liberal" in graphics and terminology. In fact, GFY isn't shorthand
for the greatest cartoon character of all time.... it stands for "Go

Fun to check out at home, but I probably should've mentioned for
those unaware, it's not entirely recommended to check out at the
office. In short: NSFW.

The file system _is_ a database. No need to add more unnescessary layers.
Here is the defacto Zend benchmark on the topic:
http://www.zend.com/zend/trick/tricks-sept-2001.php
It doesn't work for me however, some header/include error.. maybe
there's a mirror or a cache of it some place. Or perhaps you can
persuade Zend to fix it back to a working state.

Hi,

$time -= $years * 60 * 60 * 24 * 365;

$time -= $months * 60 * 60 * 24 * 30;
$weeks = floor($time / 60 / 60 / 24 / 7);
$time -= $weeks * 60 * 60 * 24 * 7;
$days = floor($time / 60 / 60 / 24);
$time -= $days * 60 * 60 * 24;
$hours = floor($time / 60 / 60);
$time -= $hours * 60 * 60;
$minutes = floor($time / 60);
$time -= $minutes * 60;
$seconds = $time;
$amount = 0;
$unit = '';
if ($years > 0) {
$amount = $years;
$unit = ' year';
if ($years > 1) {
$unit.= 's ';
}
}
elseif ($months > 0) {
$amount = $months;
$unit = ' month';
if ($months > 1) {
$unit.= 's ';
}
}
elseif ($weeks > 0) {
$amount = $weeks;
$unit = ' week';

$unit.= 's ';
}

Not really. The is far more more memory and network-bound than CPU-
bound.
It's not an excessively strong cipher so I doubt it has much effect at
all, especially when compared to the expense of fetching from a DB
server.

good article. I've also realized long ago that I only need user id in to
be stored in the session, and also considered storing that in some
encrypted cookie, so I might just take and use your solution if you
don't mind ;)

Not really. It is just a high level concept that users get roles.
Then in your code you define what roles can do. If you're into books
on tape check this podcast [1] out.
A few years ago the PEAR people were pimping something called LiveUser
[2] which now seems to be dead. Kind of ironic too since I remember
at the time everyone was saying stop working on your own and use ours.

I'm probably wrong on this, but I think the point is that it doesn't
matter the actual value of the constants. As long as you're using that
constant (which has a unique value on each request)... well, wait.
Maybe I don't understand either. Ha!
I do understand the security aspect though. It's like a password that
changes quite frequently - it would be, for all intensive purposes,
impossible to guess.
Oh, I have an idea! Let's say your users are defined this way in the
database:
user_level: ADMIN, GENERAL_USER, LEVEL_ONE_USER, etc...
Then run your comparison, e.g.:
if (defined ($user['user_level'])) { ... }

Here's what I understood it to mean :) The numbers that I was using
are unimportant.. It just needs to be consistent throughout the entire
application. Ie if 50,000 = Root 50,000 has to ALWAYS equal root. in
that same fashion if 0 = root 0 always has to be root. Both are just
as valid, and it's just a matter of design.
I could also use a "Level1", "Level2" etc type setup... All of it
works, and it's just semantics and programming styles. I don't believe
that either way is any more secure then any other way... At least of
what I have mentioned here...
If I'm wrong though, I'm open to suggestions! :)

You certainly can do that, but the problem is, if it doesn't come
down to numbers (lower-means-higher[1]), then you're defining a single
set of privileges per level. This means that each escalated privilege
level would either have to be associated with an array of either
permissible access codes, or (more overhead) would require an array of
all levels defined. Then, when you add a new level, it would have to
be explicitly defined or otherwise become a child of a parent level,
using inheritance.
[1] Using the integer method, this can be avoided. If you're
number is 0, you're the equivalent of root on *NIX. You are God in
the eyes of the system. You can do anything at all. Now, say your
number is 10. You inherit the privilege set of users >=10, but NOT
root-level privileges. Your guest users may then have a code 99,
which may be your highest number. This means they have no privileged
access, only general browsing.
Keep in mind, especially, that you don't have to limit yourself to
INT in the database. You could - and probably should - use a
FLOAT(2,2) field instead. This means you can have up to (100^2) - 1
specific levels that will inherit privileges from numbers higher than
the user level. Counting 0-99.99 gives 10,000 combinations, so root
could have up to 9,999 inherited levels below its own.
If, however, you want to restrict each level to one privilege set,
and one set only, then you can use definitions or any other method.
You'd just need more data than a single number if you later decided to
expand and use inheritance.
In any case, the idea is a lot simpler than it probably sounds by
now, but it's a fuller explanation for those interested.

I meant as opposed to the session-handling method I sent in the
other thread. However, you may want to look into having JavaScript
handle the session-watching, and report to the server via AJAX calls
every 30 seconds or so. If JavaScript doesn't PING the server at
least once every thirty seconds, then you know either the user left
the page or closed the browser. If it does, on the other hand, then
the PHP side of the AJAX routine simply updates the
[database/file/session info] to show that the user is still active.

Hum. Then we rely on JS to implement security with conections. And JS is
anything but secure AFAIK.
I want to prevent one from taking over a session from one who left the site
and left his desk for a moment.
What if that connection were two servers communicating together !?
Any crooked mind could then steal the latent session and start fire in the
system(s).

All things that would've been good to know from your first

The question remains the same and the initial problem is still the same.
My first concern is to avoid abandonned sessions from beeing stolen.
The extention of that problem is automation between two servers, like from
branches to the main office.
In that case, encryption is not a solution. It doesn't even block
cross-browser action.
Apache has mod_unique_id that could be usefull but it's not the final answer
IMO since it produces a unique ID based on a quadruple built on UTC, the
PID, the IP and a counter. That doesn't tell if the socket is still open but
only the last request the server satisfied.
For small applications maybe a cron like you gave could be a solution but
even so, will you set it to run eveny 30 seconds or so ?? I think it could
be somewhat heavy for the server. Just imagine 60 simultaneous visitors.
I would rely on JS to send an ID every 30 secs or so and wait for a new ID
based on the preceeding one. Something like mod_unique_id.

Greets all!
I am working on a minor project for work for entering inventory information
for servers we ship out.
Here is my plan:
First page -
Get client name, number of servers, and find number of miscellaneous
equipment(s) being shipped (UPS's, monitors, etc)
From there, create a loop to run through each server based on number of
servers input on first page. Each server will come up as a new page.
Each server can have x hard drives, the number of which will be put in by
the user, and the form will be generated by a loop based on the number the
user puts in (ie: either generate the form based on submitted number of hard
drives, or have user put in a drop down and use some javascript for the
rest).
I'm still planning this out... my major concern is how would I maintain
values between pages? I'd like to have a summary printed before actually
storing values into the database. I'm going to start throwing together some
code, but I just wasn't sure how to maintain the values. The first version
is most likely just going to be one really large form, but obviously this is
going to be ugly and not so easy to work with considering the variances that
the different servers have.
Any suggestions would be welcome.

Keep in mind, it'll only work on the same server and same domain.
Otherwise, you may want to look into using wildcard cookies.

Do the erors have anything to do with string expected assuming constant
or similar? Maybe you have multiple errors because you don't quote your
strings?

Subject: [PHP] Error handling
Hi,
I need help with a simple script that i made for handling errors. The problem is that the script displays the same message several times while i want it displayed just one time.
He is the code:
<?php
function error_handler($errno, $errstr, $filename, $lineno, &$context)
{
if ($errno == E_STRICT) {
echo "you are in the function error_handler<br>";
echo $errno. "<br>";
}
}
set_error_handler(error_handler, E_STRICT);
ini_set('error_reporting', 0);
$conn = mysql_connect(localhost, root, iolfsyd) or trigger_error("connection au serveur failed",WARNING);
?>
Thanks

I went to the page, but I didn't find a search box and what not. Is there a
way to search the archives? Else when I get home I'll just create a script
to DL all the links to a page then create a simple search box.

You might want to think about what you're actually considering doing
with that script before you go that. A little thought will probably
put you off the idea quickly.

Also, in case MARC goes down for whatever reason, there are a
number of other sites.
http://dir.gmane.org/gmane.comp.php.general
http://www.nabble.com/PHP---General-f140.html
.... and a ton of others which you can find on Google.
My personal favorite is GMANE, but that's because of the fact that
I'm an old-school BBS/Newsgroup hack, and I like the added list
metrics.
