(Don't ask why) 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? Cheers, tedd 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! d 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?

Well, after some more testing I'm almost sure it is some kind of strange
minor bug... so I've submitted a bug report:

Why do you put ?php echo...? inside an echo statement in php space?
I think you may have mis-readed the code, I can't find where I put an ?php
echo inside an echo. I do a lot of opening/closing tags which contributes to
messing things up estetically but it works...
Any way, the posted code had a lot of remniscants of the production code,
here is a simplified version which does the same as above but .. well,
simplified :P
?php
date_default_timezone_set('America/Santiago');
ini_set('memory_limit','1M');
ini_set('display_errors',1);
error_reporting(-1);
function my_error_handler($errno = '0', $errstr = '[FATAL] General Error',
$errfile = 'N/A', $errline = 'N/A', $errctx = '') {
global $clean_exit;
if(empty($clean_exit)) { // if isset or !empty, the script would have
been exited cleanly.
ini_set('memory_limit','16M'); // This would be just to have enough
memory to print out the error.
echo 'h5-- BEGIN ERROR --/h5Error Ndeg;:

echo 'h5-- END ERROR --/h5';
die(); // shutdown_function == manual die() or else it will continue to
execute.
}
}
set_error_handler('my_error_handler');
register_shutdown_function('my_error_handler');
for ($i = 0; $i 15000; $i++) $a[$i] = mt_rand(1,255);
$r['print'] = (string)$a[1]; // Just to asign something to that variable.
echo 'pEverything fine./p';

Would this be a bug or is this expected behaviour? I have tested this on PHP

This seems to be your error. You set $errctx to be a string. But later
on you use it as an array.
Remove the = '' part. And it will function as expected.

[PHP] Adjusting Session Times
We just got a client whose requirement is that user sessions expire after 30 minutes of inactivity. Our other clients are happy with not having their sessions expire during the work day (i.e. life is 8 hours). I am using a MySQL database to store the session data. My thought is to adjust the session expiration in the table based on the client currently logged in. Is this a good approach or would there be better ways to do it?

Re: [PHP] Adjusting Session Times
My thought is to adjust the session expiration in the table based on the client currently logged in. I don't know if there's a better way, but I would probably just do that. The expiration would be set to whatever the client's preference is, and default to 8 hours if he doesn't have one. You may want to set some checks to ensure that the client's preference is within a specific range (e.g. between 30 minutes and 16 hours). Chris.

Then when I fetch the session from the database, the WHERE clause includes a condition that the number of minutes elapsed between the current date/time and the time stored in the session table is less than the session lifetime (maximum duration of inactivity for that session).

I don't know how others solve this, but my solution is pretty
straightforward (see code below).
I require this code for every script that is in the secured area.
Simply put, if the user runs a script, then this script is also run.
As a result, if the user is not logged in they are directed to the
login script. If the user is logged in, but has exceeded the
expiration time due to inactivity, then the user is redirected to the
same login script with a GET value to trigger the login script to
report that they timed out due to inactivity.
I find it bad practice to tell a user that they are not logged in
when they did log in. It's better to explain why they have to log on
again.
Now, with respect to your storing the expiration time in the
database, that could be done easily enough by this script accessing
the database, getting, and setting the time-limit -- OR -- at the
start of any logon have the script pull the time-limit from the
database and store that value in a SESSION. Either way would work.
In any event, this is what I do.

Re: [PHP] Adjusting Session Times
Tedd,
I really like your solution. The idea of storing the expiration in the
SESSION makes it easier for me and makes it more flexible. Someone else had
provided a solution that would actually allow me to take it down to a user
level if I needed to. I loved the idea for flexibility but would have required
a major rewrite. Your idea gives me the flexibility and doesn't require any
major rewriting - just a little tweaking.
Thanks!

[PHP] Image question for runways
Hi,
I am trying to create an on the fly image of runway layouts but am
hitting a brick wall.
I have both the starting and ending coordinates of each runway, it's
length, as well as it's angle of direction (heading).
I can draw one runway without any problem, but where I am falling short
is how to 'scale', if that is the right word, the other runway(s) to
display properly in a 500x500px image
function imagepolarline($image,$x1,$y1,$length,$angle,$color)
{
$length=($length/500)*20;
$x2 = $x1 + cos( deg2rad($angle-90)) * $length;
$y2 = $y1 + sin( deg2rad($angle-90)) * $length;
imageline($image, $x1,$y1,$x2,$y2, $color);
}
//'base' coords
$x1=200;$y1=200;
$scale=1;
//if first runway
if ($d==0) {$xbase=abs($lon1);$ybase=abs($lat1);}
//for all others
else
{
$x1=$x1+(($xbase-(abs($lon1)))*$scale);
$y1=$y1+(($ybase-(abs($lat1)))*$scale);
}
Here is some test data if that would help:
length,lat_start,lon_start,heading,lat_stop,lon_stop
6869,38.8424,-77.0368,355.5000,38.8612,-77.0387
4911,38.8423,-77.0408,26.,38.8544,-77.0333
5204,38.8617,-77.0438,142.7000,38.8503,-77.0327

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

can
explain the error.

This seems to be your error. You set $errctx to be a string. But later on
you use it as an array.
Remove the = '' part. And it will function as expected.
You're right... However I don't like leaving non-default value in functions
so I did something like if(empty($errctx)) $errctx = array() in the first
line of the custom error handler which threw out the error message and
everything works ok now.
But -and correct me if I'm wrong- isn't isset (or empty) supposed to return
a FALSE whenever that variable doesn't exist?
With your help, I could reduce the test case into:
$asdf = 'hello world';
if (empty($asdf[4]['inventing'])) echo 'nice little world';
if (isset($asdf['inventing'][6])) echo 'little nice world';
// This works ok.
$asdf = '';
if (empty($asdf[4]['inventing'])) echo 'nice little world';
if (isset($asdf['inventing'][6])) echo 'little nice world';
// This returns E_NOTICE
Shouldn't these 2 examples work exactly the same way? (AKA as Nº 1). If
not... why not? Both are string types, onyl difference is that one has no
characters in it while the other does, but essentialy they are both the
same.

However, the problem can be worked around simply, for some reason the timeout generally only happens with the first call to view a mailing list, after X minutes of inactivity. Thus, I simply subscribe to a few different PHP lists (like .soap .test and general) then when I open thunderbird I quickly click a list I *don't* want to see, then click on .general, .general then loads nicely as expected letting the other one timeout :) It's hardly a fix, but it works - may be worth checking if this is the case with the latest thunderbird revision and then reporting it as a bug (in either thunderbird or the mailing list software that PHP is running).

It may be worth storing sessions in something like redis [1] instead, which let's you expire data [2] after a given time, then you can configure however you want easily. The other benefit is that sessions will be extremely fast given that they'll all be stored in ram :) [1] http://code.google.com/p/redis/ [2] http://code.google.com/p/redis/wiki/ExpireCommand Best, Nathan -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Question about news.php.net
Good to know there's a workaround. I am thinking of using one (or more) of the old VOOM boxes to mirror the news server for NNTP-only access. Sent from my DROID. Apologies if formatting is off or I'm top-posting on a list.

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. 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 the HTTP-based RSS and/or RDF feeds if it continues to be an issue. In addition, if you continue to have problems, file a bug report at http://bugs.php.net/ and we'll look into it further. Dan, Mike, I can confirm this happens all the time in thunderbird, and always has for many years now, on all PHP NNTP lists. However, the problem can be worked around simply, for some reason the timeout generally only happens with the first call to view a mailing list, after X minutes of inactivity. Thus, I simply subscribe to a few different PHP lists (like .soap .test and general) then when I open thunderbird I quickly click a list I *don't* want to see, then click on .general, .general then loads nicely as expected letting the other one timeout :) It's hardly a fix, but it works - may be worth checking if this is the case with the latest thunderbird revision and then reporting it as a bug (in either thunderbird or the mailing list software that PHP is running).

On his way out of the office:

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.
I fear this is the implementation needed to make boss see sense, however..
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.
The main problem here is in using a stateless protocol (HTTP) in a
stateful manner (with sessions), it makes this, technically, impossible.
That said, you could do this in a stateless manner quite easily by
giving the boss full control of granting and denying access, that way he
is always accountable (with his described nature, it might be good for
the buck to stop with him, rather than your code). I'd suggest having a
simple boolean flag, usersCanAccess and giving him a button to toggle
the flags state from true to false. Real life implementation could be an
empty file which is `touch`ed and `unlink`ed, php implementation being
an if(file_exists('boss_man_say_okay') ){ // let monkeys work } type
solution.

Now on my follow up question: [Note: I think it is related to the issues discussed above hence keeping it on this thread but if I am violating any guidelines here, do let me know] One reason the aforesaid questions got triggered was that in our company right now, there is a big discussion on moving away from apache+mod_php solution to nginx+fast-cgi based model for handling all php-based services. The move seems to be more based some anecdotal observations and possibly not based on a typical php-based app (i.e. the php script involved was trivial one acting as some proxy to another backend service). I have written fast-cgi servers in the past in C++, and I am aware how the apahcefast-cgi-servers work (in unix socket setups). All our php apps are written with apache+mod_php in mind (no explicit resource mgmt ), so this was a concern to me. If the same scripts now need to run 'forever' as a fastcgi server, are we forced to do such manual resource mgmt? Or are there solutions here that work just as in mod_php? This reminded me of the cli daemons that I had written earlier where such manual cleanups were done, and hence my doubts on this nginx+fast-cgi approach. thx, Ravi -- Per Jessen, Zürich (14.6°C) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
