Re: [PHP] 1984 (Big Brother)

[viraj]

got another idea.. setup the database on a machine which can detect
the availability of the boss. if the boss machine is on.. and
connected to network.. the script will try to verify the availability
of the bosses's ip and interface hardware address. (if the boss change
the nic or machine, mac has to be updated manually in the script) and
starts or stops the database.

this can be done with bit of shellexec and bit of shellscripting, if
on linux with 'arp' (all employees and boss has to be in same subnet i
guess.. )

It would, wouldn't it?

Anyway.  Something you could do is a script that turns mysqld on and
off:  set him up with an SSH connection to the server, and he can run
the script when he gets in to turn it on, and run it again whenever he
leaves to turn it off.  A cron job to turn mysqld off at whatever time
he usually leaves would probably be a reasonable failsafe.  If he
really wants you could probably link it to a swipe card system or just
a keyboard on his desk (enter your PIN to turn it on, enter it again
to turn it off).

All that aside, I can't help feeling that this has gotten into "I'm
afraid you know too much for us to let you leave:  Guards!  Take him
away!" territory.

I have had this problem every day for years.  I can read a message and
then click another one and it times out.  It does this for hours at a
time.  Also, many times when sending a reply it times out.  Just learned
to live with it because I don't want mailing list mails either.

It would be cheaper to employ the same method used on some
lawnmowers and required on Jet Skis and Skidoos: a cable with a clip
worn by the rider.  The rider falls off, the cable releases from the
vehicle, disengaging the throttle and cutting the engine.  The boss
stands up, his entire infrastructure collapses, everyone's connections
are closed, and all PCs subsequently catch fire.

Realistically, a simple desktop-based application running in the
system tray (presuming Windows) would send a kill signal to a
predefined script to issue safe closing routines to the database
first, then any other systems he wants to close out.  It could even
have simple options to poll if there's a screensaver activated, which
would initiate the process automatically, should he choose to be
extremely paranoid.  The same could be automated to work in reverse,
to automatically bring the systems up, when the local desktop session
becomes active (from hibernation, logoff, or screensaver), or even
with an override ("Pause Sessions") by right-clicking the systray
icon.

It's no surprise to several here that I'm not a big fan of
Windows but I do still like to stay on top of programming
languages, and at least give each one a try.  Something of interest to
no one: my first full-production, open-source project that included
PHP was actually a combination of a PHP server-side script and Windows
client script, written in VB, back in 2000.  It was named phpCourier,
and was used as a client-server CMS for simple news postings (before
"blog" became a catchphrase).  It was downloaded a few thousand times,
and then I quit hosting it.  I may actually have that server with
those files and a bunch of other old projects in my basement.  Now I'm
suddenly interested in unpacking and organizing everything.

 In other words, when the boss is not logged on, then his employees cannot
 access the business database in any fashion whatsoever including checking 
 to
 see if the boss is logged on, or not. No access whatsoever!
 
 Normally, I would just set up a field in the database and have that set to
 "yes" or "no" as to if the employees could access the database, or not. But
 in this case, the boss does not want even that type of access to the
 database permitted. Repeat -- No access whatsoever!
 
 I was thinking of the boss' script writing to a file that accomplished the
 "yes" or "no" thing, but if the boss did not log off properly then the file
 would remain in the "yes" state allowing employees undesired access. That
 would not be acceptable.
 
 So, what methods would you suggest?

Well, if we are going down this route, many new laptops are offering some form 
of biometrics for access. If your client has one, you could potentially launch 
a script to start/ stop the db at that time. 

Or if we follow the new password suggestion, his morning login could run a 
script to reset and email all users their passwords automatically.

If this persists, I'll look into the alternatives you suggest, but 
that's another hill to climb when all I'm trying to do is learn PHP and 
web and mySQL and javascrip and...   :)  (not complaining, just that 
right now I've got a lot on my plate and the scope of new things just 
seem to keep expanding faster than I can get a handle on it).



In addition, if you continue to have problems, file a bug report at
http://bugs.php.net/ and we'll look into it further.

Thanks, I did that. In the process I found a 2005 bug report that said 
nntp was deliberately throttled to discourage its use... :)


As part of the bug report I included a link to an image of my nntp config.

I don't believe that we've been having any issues with the server,
no.  Are you using NNTP to connect?  You may want to consider using

[PHP] Could this be a bug?

[Camilo Sperberg]

I have some really strange behaviour going on here, and I think it could be
a (minor) PHP's bug.
I am not really sure about what happens internally, but my best guess would
be that after a memory exhaustion, when I try to execute a custom error
handler with the register_shutdown_function (which is executed even after a
fatal error) and try to access the element that provoked the memory
exhaustion, no error should raise instead of *Uninitialized string offset:
0.

I have prepared a little test case to reproduce the error and (I hope) can
explain the error.

PHP v'.PHP_VERSION.', error N° '.$errno.'';
?>-- BEGIN COPY --Error N°:'.$errno.'';
?>Error Detail:'.$errstr.'File:'.$errfile.'Line:'.$errline.'Debug:';
if (isset($errctx['r']['print'])) echo 'THIS LINE GIVES THE ERROR,
WHAT SHOULD IT RETURN?';
?>-- END COPY --Everything fine.';

$clean_exit = TRUE;

*
Would this be a bug or is this expected behaviour? I have tested this on PHP
v5.2.14, I've not tested it yet on 5.3.3, but I guess it would have the same
behaviour.

Greetings!

[PHP] Question about news.php.net

[MikeB]

If there is a more appropriate place to ask this, I apologize. Please 
point me in the right direction.


I understand that the news server is based on a mailing list, but I 
can't handle another high-volume source dumping stuff into my email 
(even if I filter it into a separate folder) so I am trying to subscribe 
through the news group.


However, getting access seems to be hit-and-miss, since I more often 
than not get a message that the connection to news.php.net timed out.


Is this an indication that the server is just very busy? I don't get 
this on any other news server I'm using on the smae news reader and I 
have gotten this on two different news readers that I have tried.

So, what methods would you suggest?

What operating system is he using?

Does he (for example), log into his computer and logoff/shutdown when
he goes home?

If he is using Windows (and I'm sure there are many ways to achieve
this), then in the Startup folder, a small PHP script which sets a
flag "I'm here", would allow the DB to know he's at least logged in.

There are different ways to do this.
http://www.experts-exchange.com/OS/Microsoft_Operating_Systems/Windows/XP/Q_21195727.html
covers login/logout/startup/shutdown.


Do they have a clock card system for clocking in/out the building?
Could you read the database that the clockings are logged in? An odd
number for the day = he's in, even = he's out, missed clocking =
screwed/guess.

Ideally you want to "hook" into his normal activity if you can.

I'm pretty sure I'd have run for the hills after my first meeting with 
this client, but if you're sure you want to proceed ... Beyond the 
options mentioned, you could set it up so that the boss would log in 
each morning with a session that times out at the end of the work day 
(8, 10, 12, w/e hours later).  To make it even more secure, you could 
have the boss create new logins for each employee at the start of each 
day.  Since yesterdays passwords will no longer work, the boss will have 
to be there to issue new passwords to whomever he deems worthy of access 
on this day.  These passwords would of course expire at the normal 
leaving time, so if someone came in late for a password at 4pm and work 
ends at 6pm, their password would only last two more hours.


All in all, I'd still grill him more about what it is he actually wants 
and why, as all of the ideas presented thus far have at least a dozen 
different ways things can go wrong.  Putting the app on the bosses 
computer sounds great and all, but if he's sick or away on business 
suddenly no one in the office is doing any work.  Or when his hdd gives 
out or is replaced and IT's backup system wasn't as great as it could 
have been you'll have fun getting paid to re-do everything.  Having 
everything require a usb stick to launch sounds secure, until he loses 
the stick or forgets it at home one day.  For fun I'd suggest tagging 
him with a microchip which your application will constantly scan for and 
only activate when he's within a certain radius of his desk.  Retna 
scans shouldn't be overlooked either. 


May the force be with you on this one.

Yes I've been following this post purely in the hope that someone gets Tedd
is explain the client's "logic" on this one.  It's one thing for a layman to
have this kind of requirement, but another entirely for them to STILL have
it after an explanation.  I mean part of consulting is to tell the client
when they're wrong, for someone to not heed that when they are paying for
the advice is mind boggling. *sigh* if only everyone were perfect like me...
 :p

"Hey lets pay someone to consult us on a subject that we're ignorant of."
"Great idea! And when he makes a suggestion we can totally ignore him! SQL -
Shmeequal"


Rant aside; I would defer the logistics to the client.  He wants the DB to
shutdown when he's not in the office? Ok no problem - not what it was
designed to do, but no problem!

"How would you like the system to be aware of rather or not you're in the
office? It can assume you are between these hours; You can log into a screen
that unlocked it, but then you have to logout; we can put a motion detector
in your office; ... etc."

This would put the consequences of the system off on the client. Because if
this system works then there will be consequences and you'll look like a
jerk  :-)

Btw, are there no cron / batch jobs that need to run over night?

You sure know how to pick'em Tedd. 

This is the second "whacky" client you've posted about on the list...

This guy sounds like a real control-freak (read: tool).

One other thing I'll throw out is the use of a crontab to start/stop mysql
during "boss's hours". I don't have a complete solution for you as I just
don't care enough about helping this Dbag lord over his employees like
that, but I suspect you could have "/etc/init.d/mysql start" or "stop" at
some pre-determined times like 8am - noon. Then noon till 5pm. Or
something.

RDBMS are not really designed to be turned on and off like that.

Another option is to maybe use M$ Access instead (which does have a
multi-user mode). Use ODBC to connect via PHP to it. So then he would start
up the DB when he likes and shut it down when he likes. (note that a logout
of Windows will NOT prevent the ODBC connection as it is a service -- as
God intended RDBMS to be)
http://www.configure-all.com/php_access.php

This guy is making me angry just thinking about it!

@Tom: I have compiled php with pcntl on and this has never been an
issue. It works well (on a linux setup), and I have deployed
standalone daemons with out any major problems. I have a home-grown
'preforker' framework (which I hope to share soon) which can be used
to exploit multi-core boxes.

@Shawn: It is not academic. There is a follow-up I am planning based
on the doubts above. I have deployed such daemons in the past with
some assumptions on (2) by doing manual cleanups - e.g. closing curl
connections, closing up db handles etc...  Really want to understand
how php works in such setups outside of apache+mod_php.

Ravi

It seems to me that almost no matter what method you choose, you're
going to have to ask the client to do something manually - whether
that's logging out of the website, shutting down his computer,
removing a thumb drive, or whatever - so you might as well be upfront
about that and see how he responds.  Provide the different options and
get them to choose one, at some point they'll need to take a bit of

hi tedd,
if steve's idea is something doable.. why don't you consider setting
up the mysql data dir on some removable media (thumb/flash drive)?

so the boss can pull it off if he is going home. and it's easy to
detect this in code and display a message to system users, something
similar to that 'mysql server has gone away' message. (boss has gone
away) :)

Anybody that tells him it can be done is lying through their teeth and
will just be stealing his money. He probably deserves what he gets in
this case.

This may be the only way to do it, but it shouldn't be too hard to
figure out. If he turns off the computer every time he leaves his desk,
it can be installed anywhere, even as a service. But if he leaves the
computer on, it has to be on his desktop, probably with an entry in his
Start directory to start it when he logs in. But he has to actually log
out of the desktop to block access, not just leave it in the screen
saver.

here's a silly idea...

put the database on his computer (or the entire app).  that way, when
he's *there* he is logged in.  if the computer is off, he's not there,
the app wont work (and the database).

Re: [PHP] Standalone WebServer for PHP

[Steve Staples]

Wow... this thread SURE went WAY off my original topic...


All I was looking for, was a "webserver" that would serve "PHP" pages,
that was not "installed" on the machine.   Now, if the machine was *nix
or Windose, it didn't matter.

I know in Python, you just have to install python, and then you can use
Cherrypy (but i dont know python, nor do i want to create the app i am
creating with a language i dont full know/understand).

Anyway, I spent a bit of time on the interwebs this weekend, and after
trying just about every one i could find, I am just going to go with
XAMPP, and remove all the stuff i dont need, and trim some fat, and
remove all the hard links to the /opt/lampp directory in linux, and
figure out what it is in windose later...

anyway, thanks for all the ideas.

Steve.

What operating system is he using?

Does he (for example), log into his computer and logoff/shutdown when
he goes home?

If he is using Windows (and I'm sure there are many ways to achieve
this), then in the Startup folder, a small PHP script which sets a
flag "I'm here", would allow the DB to know he's at least logged in.

There are different ways to do this.
http://www.experts-exchange.com/OS/Microsoft_Operating_Systems/Windows/XP/Q_21195727.html
covers login/logout/startup/shutdown.


Do they have a clock card system for clocking in/out the building?
Could you read the database that the clockings are logged in? An odd
number for the day = he's in, even = he's out, missed clocking =
screwed/guess.

Ideally you want to "hook" into his normal activity if you can.

I'm helping someone else, so not my setup. They want to disable the
gmagick extension.

I'm waiting for him to get back to me on system setup.

I'm not exactly sure why this extension requires disabling in a single
directory ...

All things I should have asked first, but my first impression was that
there was no way to do a ...

-extension=php_gmagick.dll (or .so).

I'm thinking about a shared hosting where a user may have a conflict
between their own classes and an extension's.

Namespaces could be the answer here, but you can't just put a 1 liner
in and have all the code fixed.

Re: [PHP] New to PHP and the list

only if register_golbals is set to ON in php.ini. This is a very bad
practice and should be avoided. Use $_POST['MAX_FILE_SIZE'] instead.
But in this case dont use the post variable also. define a constant in
your configuration file and use that constant. The only use of
MAX_FILE_SIZE  is to inform the browser that "dont allow the user to
upload files which are > MAX_FILE_SIZE".

A malicious user can ALWAYS modify the data. You will have to always

[PHP] Counting Children!

[Sridhar Pandurangiah]

Hi

I have an XML generated by another computer application. The format is
as below. (Don't worry about the data in the XML. Its the test
data).

I am able to locate the correct member bill using XPATH.
However I have hit a bottleneck. I am unable to echo all the  
elements. This is what happens


$row = simplexml_load_string($member->asXML());

echo $line->particular1;
echo $line->amount1;
echo $line->particular2;
echo $line->amount2;

Echoes the first  element of the member bill. If I add the same 
set of statements it echoes the second  element and so on. But 
then if I put the following code which I feel is correct

$row = simplexml_load_string($member->asXML());

foreach ($row->line as $line);
{
echo $line->particular1;
echo $line->amount1;
echo $line->particular2;
echo $line->amount2;
}

Echoes only the last  element of the member. Can someone tell me 
what's wrong

Re: [PHP] 1984 (Big Brother)

[kranthi]

i m not sure if i usderstood your question completely.
by database you mean something like phpmyadmin, right ?

i would save the latest session id of the boss in a file, and every
time an employee tries to log in, verify the time stamp of the session
file in the tmp folder.
and if the boss logs out... clear off the tmp folder to ensure that
the employees dosent have further access.

Just connect them to a router and don't connect the router to the WAN.
Each machine will get it's own IP address (assuming that the router is
running a DHCP server).

Not entirely sure what you're asking, but could you maybe achieve
something like this with a WAN using a VPN?

Thanks,

Ash:

I'm sure this is an obvious question for many on this list, but I'm not
above showing my ignorance.

I guess what I am asking -- if a client wanted an application written
(in web languages) so that their employees could link all their
different computers together and share/use information using browsers,
is that possible using a server that is not connected to the Internet?

Look, I know that I can solve my clients problems by finding a host and
writing scripts to do what they want -- that's not a problem. But
everything I do is open to the world. Sure I can provide some level of
security, but nothing like the security that can be provided behind
closed and locked doors.

So, can I do what I do (i.e., programming) without having a host? Can I
install a local server at my clients location and interface all their
computers to use the server without them ever being connected to the
Internet?

Maybe I should ask my grandson. :-)

Cheers,

If the network is set up (as most business and home networks are these days) to 
use Network Address Translation (NAT) at the connection point to the world, then 
you shold be able to achieve this.
NAT is where you have an internal network using private addresses (often in the 
192.168.xxx.xxx range) but all outgoing traffic appears on the internet to come 
from one public address.


So you configure your web server to accept requests from only the internal 
addresses. With Apache you could do this on a per-directory basis, even, so the 
web server could have public content (visible to all client addresses) and then 
have private content in subdirectories which only accept clients on the internal 
network addresses.


There is a possible loophole due to IP address spoofing, but I suspect that your 
gateway device (firewall, ADSL or cable router that connects you to the world) 
will block those sort of clients.
