Hey, Jason, since you really need this BUG fixed, and the PHP developers would welcome good, well-documented, and tested code ... Why not devote some of your precious time to helping them along? If _you_ write, document, and test the code, and then pass the code to the development team you'll stand a much better chance of getting it included in a future version - along with solving your current problem _and_ getting your name in the list of contributors.

Re: [PHP] REGISTER_SHUTDOWN_FUNCTION() BUG -- Please Fix.
It's a bug. spoke to Rasmus at some length about just before i posted it in the bug report. The online help page is inaccurate in describing the full functionality of the function: http://www.php.net/manual/en/function.register-shutdown-function.php REGISTER_SHUTDOWN_FUNCTION() is suppose to kick-off when any one of the following things happen -- Exit, Error, TIMEOUT or User Abort. According to Rasmus, the TIMEOUT functionality of this function works fine under Linux -- however, it's not working under Win32 ! There apparently is another bug with this function -- you are suppose to be able to call more than one REGISTER_SHUTDOWN_FUNCTION(), and they are suppose to executed in-order... some people are reporting that only the first encountered REGISTER_SHUTDOWN_FUNCTION() is executed, then the script exits. Someone needs to go through this function, pretty thoroughly, and get it working correctly. Being able to run code on a timeout, user-abort or error is critical.

You could call your xmysql method manually if you like but you can't have it called automatically if your object is unset().

On Tue, 26 Mar 2002, Jason Goodman wrote: 2 questions about register_shutdown_function. 1)Functions registered with register_shutdown_function are called after the script finishes processing. Is there a way to have a function only called when the PHP form is actually closed? 2)The function registered with register_shutdown_function does not seem to write to a file before the PHP page is closed. I need to send a message to another file when the PHP form is closed. When you say when the PHP form is closed do you mean when the user has finished looking at the page on their browser and moves on to something else by clicking their mouse? Because there's not particularly a way to do this. The connection between PHP script and browser is finished before anything even displays in the browser window (unless you're flushing the output buffer, but that doesn't help you any). You could attach some JavaScript to the page that looks for window closure and away-clickery and then sends your server a request for a PHP file in response, but that's outside the scope of this list (it's a JavaScript problem). miguel -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] register_shutdown_function vs require (with pseudocode example)
Hi,
No one has any idea on this topic? Or the question wasn't clear?

Hi again,
I read my email back and found a little hard to understand :)), so
I thought a code exmplae might help.
It's just pseudo code for explaining how my cache works:
//simplified main code
if page is in cache {
deliver the old one
register_shutdown_function(regenerate)
} else {
regenerate()
deliver
}
//registered shutdown function
function regenerate() {
if it's locked by another process {
return
} else {
lock
require_once(...);
require_once(...);
require_once(...);
require_once(...);
require_once(...);
creation of many classes
calling of many methods (the code is approx 1,6Megs)
store
unlock
}
}
The main code delivers the page and reigsters the regenerate()
function, and that's all what it should do. It takes about 0.04s,
but this time unfortunately depends on what the regenerate()
function does. If the page is locked then it finishes quickly (the
overall time is 0.04s again), but when it can be regenerated it
takes 0.25s. By the way the whole page regeneration takes 1.1s,
that's why I really don't understand the 0.25s.
I hope it was clearer with the two mails :)), and someone has an
idea of whats happening here.
Thanks for your help,
Arpi

Not a fancy example, but...
I use it in a script which loops through a database of urls to validate
them. With each loop, set_time_limit gets reset for a length of time more
than sufficient for processing a valid url. If an iteration takes too
long, the script will timeout and die without an error message. Since in
this case timeout == bad url, register_shutdown_function() allows me to
send a final query back to the database marking the current url as invalid.
Otherwise, when I start the script up again it would always have that same
url sitting at the top of the processing list where it would just timeout
over and over again (which is what it used to do--what a PITA).
You could also use register_shutdown_function() to, for instance, email
yourself information about why a script terminated and what state it was
left in. Output to the *browser is disallowed, but output to other
destinations (logs, email, filesystem, databases, etc.) still works. You
can take advantage of that.
