in reply to using parallel processing to concatenate a string, where order of concatenation doesn't matter
You expect the timeline of your processes to be:
____ / \ ---<------>--- \____/
But it really is:
_________ / ---<---------- \_________
The problem is that the updated $content dies with its process. You need some sort of IPC. Welcome :^).
Update: Or threads, like RMGir correctly suggests.
