Hi all

i have a form where my users submit some data. These data need processing, which may take quite some time. I don't want the user to wait that long, and worse, if he stops the page from loading in the browser, that may stop the processing and result in corrupt data.

I'd like to use a function or a way to keep running the processing lines on the server side, while the user is redirected to another page. It's probably something like a thread.

Is this possible?

Thanks

Running PHP scripts without having a user accessing a page is something that you shouldn't be doing for the most part.

However, in some cases, I can see it being necessary, but what you're asking is pretty unreasonable. The closest thing I can think of is creating a cron to run the php that processes data in the queue every x minutes/hours/days/weeks/etc.

It wouldn't be instantaneously ran, however.

Another method is to parse tiny bits of the data on every page load, providing you have enough traffic to initiate the parsing function frequently enough.

One last way to do it is to set a function to run after a set time on the next page load. I've seen a few PHP scheduling applications use this method.

However, none of those seem to do the background-processing that you're wanting.

To run a php file in the background regardless of what the user does:

PHP Code:

shell_exec('nohup /path/to/php -f/path/to/file.php >> /dev/null &'); 

To catch the output for logging purposes swap /dev/null to log location

I guess this should do it.
