hi Roman,
have I understood correctly that using pcntl_wait() means you can't do anything in
the parent process until all children are dead?
this seems strange. probably I'm mis-understanding and need to reread [alot of] stuff.
but if it is true how do you go about tackling the signal handling in child processes
AND at the same time have the parent process do something useful like ...
interact/direct child processes, do other management tasks whilst child processes are running?
maybe I'm misunderstanding the whole concept - it's nice to have that newbie feeling again ;-)

I have a system that forks to 'do work'. The main script sits in an
infinite loop waiting for work, when it gets some it forks to process it.
In that loop I have the following at the end...
while (pcntl_wait($status, WNOHANG)) > 0)
$workers--;
That takes care of cleaning up finished processes while running.
If the loop ends for any reason (e.g. it got stopped by a status
change), I do...
$started = time();
while ($workers > 0 and (time() - $started) < 300)
{
pcntl_wait($status, WNOHANG);
$workers--;
sleep(1);
}
That sits waiting for up to 5 minutes for all processes to end.

do whatever you want, either have a SIGCLD handler, or check one of the
wait(2)-family functions every now and then (and make sure to use
WNOHANG).

Roman, Stut and Jochem, thanks for the comments and recommendations on the
subject.
I have installed my signal as pcntl_signal(SIGCHLD, SIG_IGN) without a
specific function handler and it is closing child processes now. I could not
use the pcntl_wait because it is available after PHP 5.0 i guess.

it is enough - but I'd like to clean it up for you just a tiny bit:
1. use isset on thwe var your checking
2. strtolower() the var your checking to cover your ass on even the weirdest
webserver SAPIs (I have seen the values of 'On' and 'on' for $_SERVER['HTTPS'])
3. 'Location: ' not 'location:' (1 more 'location' and I'm a realestate agent, ack dang too late ;-)
if(!isset($_SERVER['HTTPS']) || strtolower($_SERVER['HTTPS']) != 'on') {
header('Location: https://www.mysite.com');
exit;
}

Sorry it doesn't use PHP, but this is what I do if the client wants an
entire site to always use SSL. In the web server config for the non-ssl
site, put a permanent redirection to the SSL site. For Apache I use the
following vhost...
<VirtualHost 10.10.10.5:80>
ServerName domain.com
ServerAlias www.domain.com
Redirect permanent / https://www.domain.com/
</VirtualHost>
Works great, and it retains the full URL they were aiming for. For
example, if they go to http://domain.com/somewhere they end up at
https://www.domain.com/somewhere.
I'm sure something similar is possible in most web servers.

Can someone help me with this, please? I cannot load extensions.
I setup php5 in the c:\php folder. I specified extension_dir =
"C:\php\ext".
Everything else is setup correctly because php works. for me, I can load
phpinfo file.
It would not load extensions.
I am going nuts here. Please anyone, what can it be????
Thank you.

run the phpinfo() command in a script and see where your php.ini file is
located.
make sure you are editing the correct file.

Thank you for your reply.
I have only one php.ini. I checked it.
Now, I found in the evenet log viewer that I have lots of messages like:
"Module compiled with module API=20060613, debug=0, thread-safety=1
PHP compiled with module API=20020429, debug=0, thread-safety=1
These options need to match"
And
" PHP Warning: Unknown(): Unable to load dynamic library
'C:\php\ext\php_mysqli.dll' - The specified procedure could not be found.
in Unknown on line 0."
Any ideas?
The file is there and this is the correct path.
Thank you.

The "These options need to match" warning is talking about the version of php that it was compiled against. They look like timestamps to me. So,I will assume you are trying to use a different version of php then what the extension was compiled against.
Find out what version of PHP you are using and what version of PHP the extension was compiled for and you might then have your answer.

I removed php folder - everything except php.ini file and replaced with the
new downloaded version and it started working.

hi to all,
my IT director got an idea to replace mysql with DB2. more
"power/flexibility/stability/security..."
though, for our needs, I think mysql is just fine and enough. the business
we are doing is promotional products and all online orders we have are
ONLY from our sales people. with 200-300 orders per day and averge of 5
items per order I think we really don't need that replacement.
though, don't know how php works with DB2 (assuming same quality as with
mysql).
can anybody give me some ideas and "reasons" to present to boss to NOT
replace mysql with DB2?
thanks.

I don't know how close the syntax between MySQL and DB2 is, but I
suspect you're looking at quite a bit of rewrite. Unless your
application was written specifically to work with either, I doubt it
will simply be a matter of plugging in a new database.
