PHP: Get output before script is finished

Question

I have a script named data.php that looks like this:

/* do some stuff */
echo $result;
/* do some other stuff (eg database operations) */

I need to use the output of data.php in another script but I don't want the caller script to wait until data.php is finished.

What's the easiest way to do this?

Thanks in advance!

Take a look at the flush() function: http://php.net/manual/en/function.flush.php

No webserver nor web browser involved here. Just passing data from script to script.

@Daniel flush works on the output stream regardless of context. It doesn't matter if this is a webserver or command-line.

Theoretically speaking (writing) one script should output to a stream, and the other should read from the same stream.
A good (and simple) example would be one file writes to a file on HD, the other reads from it. Simplest, but not the best.

Hmm, seems to be more complicated than I thought. Maybe I could also fork a child process for the remaining stuff...

NNNnnice, I'm totally doing that... ajax requests that just keep reading the output file. And instead of echo in the main php, we write to that output file... so clever...
