PHP Threading

Has anyone got any information or links for some tutorials on threading with
PHP?
I was looking at running a socket listener, and launch off new threads, and
co-ordinate as requests come in.

Cheers,
Graham

Graham,

The PHP cli doesn't support multithreading. You can get multiple
threads if you're running as an Apache or IIS extension and the
webserver is running multiple threads, but that's all.

That's not completely true. You can the Process Control Functions
(http://www.php.net/manual/en/ref.pcntl.php). However, they're only
avaible on Unix like systems.

That's process forking, which isn't quite the same as multi-threading.
However it can be extremely useful depending on your requirements.

Yes, but those are for multiple processes, not threads. PHP doesn't
support multi-threading.

PHP isn't good at all for threading - you'd be better of luanching a
Python, Perl or C app from CGI instead.

Below are 2 files that isolate the problem. Note, both programs hang (stop responding) with hyper-threading turned on (a BIOS setting), but work as expected with hyper-threading turned off. Note, the Windows task manager shows 2 CPUs on the Performance tab with hyper-threading is turned on. Both Python 2.3.5 and 2.4.3 (downloaded from python.org) have this problem. The operating system is MS Windows XP Professional.
