When we need to write supporting utilities or automated behind-the-scenes tasks, we develop them in PHP because, well, why reinvent the wheel? All of our database models, library functions, classes, etc all exist in PHP. From this perspective, you can see why having these types of tools/features is very helpful and even necessary. @Henk: We are an application service provider and our codebase has hundreds of thousands of lines of PHP code in it.

But we have come up with creative ways to achieve what was thought to be impossible for PHP to do. Yes I would like to PHP like programing language branch off that is more like C / C++ / Java in respects of these lower level accesses. @Henk: PHP was definitely not designed for task of such a nature.

Probably not :) But since I’m not doing degree in CS now, I like to experiment with things.

On the hand, for all but the most basic use case scenarios PHP still has a long way to go. Traditional imperative languages like Java or C# have had parallelism build in right from the start and have been gradually improving on this over the years. A nice presentation about parallel library support for imperative languages is this one: http://www.parleys.com/display/PARLEYS/Home#slide=3;title=From%20Concurrent%20to%20Parallel;talk=24576007 Ok, the language uses there is Java, but the concept in general enough to be interesting to users of other languages. I wonder though if anything like the level of support discussed in that presentation is on the radar of the PHP development team.

That will give you the biggest part of the puzzle. Er – You have to find something talking about threading and IPC with PHP.. That will give you the biggest part of the puzzle.

maybe this package: http://www.phpclasses.org/browse/package/4082.html

I have "host php" -> "child phps" approach implemented for CRON tasks. I'm not always have access to cron tasks config, so I use php file, which is invoked every minute by cron. That file simulates cron's functionality and calls required scripts. Yes, in PHP this is probably the best way – real parallelism is not very good.
