Hey thanks for the tutorial. I created a class which should help streamlining the execution of output and background functions.

It even works with gzip.

This is now working on a curled page. I am using curl in 1 php file to run a 2nd php file. I am using the above code trying to get the 2nd php file to send a response back to the 1st php file and keep working. The problem is that the 2nd php file isn't sending any response until it completes running, but that takes almost a minute. How can I send a response back to the 1st, calling php file then continue with the rest of the code and without requiring the 1st php file to wait for the 2nd file to finish?

@Ramzi - if mod_deflate is enabled on Apache, the HTTP response is getting gzipped before being sent to the client. This means PHP won't know the correct size of the response to put in the "Content-Length" header. Try disabling mod_deflate if it's enabled.

I'v tried the Example 2 but the explorer doesn't close the connection until the process is finished .

is their any configuration required in the Apache server or PHP files?

My scripts had sessions active, which was preventing the above code from working.
Adding session_write_close(); before the background task fixed it.

I had to also set header('Content-Encoding: none');
I believe this has something to do with compression, gzip or something. It probably depends on whether your server does it by default. Probably a better way is to find the compressed length.
