I've typically used cron to run my queue, but other options include having a daemon running in the background checking periodically for updates (and said daemon does not necessarily need to be written in PHP -- just needs to invoke your script that does the processing). Platform's Job Queue runs as a daemon, for instance. You _don't_ want your web application to trigger it, as you'll run into the exact situation you were having before. -- Matthew Weier O'Phinney Software Architect | matt...@zend.com Zend Framework | http://framework.zend.com/
Re: [fw-general] Continue Processing after an action is completed
This won't work on a windows host, but If you you can pass all of the proper
variables as arguments, You can try executing the task in the background via
shell in postDispatch.
Just append "&" to the end of the command.
system('php -f /path/to/file.php var1 var2 &');
It may not work on a share host either, though :)

I'm pretty sure there are unoffical RPM repositories that carry a more recent version for you. And everyone else should persue this route too, or use another Linux distro.

With this in mind, I'd suggest building a job queue. With this sort of solution, you send a message to the queue, and then a queue processor queries it periodically and performs routines pertinent to the message sent. There is a Zend_Queue proposal under review, but not yet accepted. There are also commercial solutions such as Zend Platform's Job Queue which can perform this work. You can also roll your own, something I've done before myself. Usually, you provide a callback, and the arguments for the callback, and your queue processor then does the processing. I've done implementations that used static class methods for the callbacks, as well as some that would instantiate the given class and then call the given method with the provided arguments (utilizing call_user_func_array()). -- Matthew Weier O'Phinney Software Architect | matt...@zend.com Zend Framework | http://framework.zend.com/

And I should probably go on record to recommend against action() and ActionStack, really. Most of the time if you find yourself doing that, it means you're executing application logic within your action controllers -- logic that is usually best implemented in your models. A more appropriate solution would be one of the following: * Creation of a view helper that interacts with the necessary model and builds the appropriate display * Passing the appropriate model to the view and then render()ing an additional view script within it (or calling partial() and passing the model). -- Matthew Weier O'Phinney Software Architect | matt...@zend.com Zend Framework | http://framework.zend.com/

[fw-general] Continue Processing after an action is completed
Hi Folks, I would like to be able to call an action / respond to the client and then continue on with some further processing. I have tried a couple of things: - Using fork: - http://www.php.net/manual/en/function.pcntl-fork.php This doesn't work on my windows installation and i'm not sure it will be enabled on my hosting. Using a headers hack method:- http://www.brandonchecketts.com/archives/performing-post-output-script-processing-in-php This seems to work the first time, but not the next time you call it. Register Shutdown function http://uk2.php.net/register_shutdown_function This doesn't work at all - it just blocks until the "other processing" is finished. Is there anything that works with the Zend Framework? Any other ideas?

If you're indeed using Dojo, consider using ContentPane's with the "href" attribute pointing to actions that have the content you wish to display. That approach will require more requests, but be very dynamic. The other possibility is to use one of the following: * partial() view helper allows you to specify the module in which to look for the view script. * action() view helper dispatches another action and returns the content * ActionStack action helper/plugin will allow you to specify one or more actions to perform during the request lifecycle. Have each render to a distinct response segment, and build the final output in your layout script. In terms of performance, ActionStack will be faster than partial(), which will in turn be faster than action(). However, partial() and action() allow you to build the view within a single action view script, while ActionStack will require a different strategy. -- Matthew Weier O'Phinney Software Architect | matt...@zend.com Zend Framework | http://framework.zend.com/
[fw-general] INI routes reqs
