PHP Curl output buffer not receiving response

I ended up running my 2nd file first and my 1st file second. The 2nd file waited for a 'finished' file write that the 1st file did once it, obviously, finished.

This could be just what you're looking for. Forking in PHP:

A process divides in two. One is father of the other. The father can tell the client he just begun and the child can do the job. When the child finishes, he's able to report the father which can also report to the client.

Keep in mind there are many requirements for this to run:

• Linux
• CLI or CGI interface
• shmop, pcntl and posix extensions (require recompiling)
