Hello What about fork() in php ? I have tried to understand c language yesterday, and I have write that in /ext/standard/basic_functions.c: PHP_FUNCTION(php_fork){ fork(); } (and a few lines to decalare this function) And it's work ! Now I can fork my php scripts with the php_fork() function :) Is it possible to hope that a same function will come in futures versions of php ?

Any chance to see fork() support for Win32 in the near future? On Sun, 14 Nov 2004 16:48:14 +0100 (CET), Derick Rethans <derick@php.net> wrote:

But as you said support for spoon() can be added. :-) Andrey Steph wrote:

No, win32 has no such concept. Derick

Can't it be emulated? On Sun, 14 Nov 2004 16:53:53 +0100 (CET), Derick Rethans <derick@php.net> wrote:

The *concept* doesn't exist on Windows, so no. Derick

The *concept* of copying the address space of a process to another process doesn't exist? How does the Win32 loader work? Btw, I'm not aware of if the PHP engine is multithreaded, but if it's possible to run multiple scripts in multiple threads of the same process, that could do the trick.

No clue - it's not open source you know. But it does NOT fork something.

It's not multi-threaded, nor will it ever be. It's not made for it and all previous attempts at making this work failed. There is no way. Derick

Perl emulates it pretty nicely on windows http://www.perldoc.com/perl5.8.4/pod/perlfork.html Aaron

My point exactly. However, I *know* that perl emulates it using threads. But, when thinking of it, Cygwin emulates fork() by copying the address space of a process to a newly created process. It's a bit slow, but at least it works. Guess getting into the kernel mode driver land to create *actual* fork() on win32 is a bit beyond php development.

Which we don't support.

and is buggy.

Services for Unix does this kind of thing; it's buggy too. It would be cool to have better threading support and perhaps emulated fork (it's not something I would use), but I can't see it happening without some funding behind it. --Wez.

Heh, ActiveState did it after they received funding from Microsoft. Guess that's not gonna happen with PHP. Ever. On Sun, 14 Nov 2004 19:25:09 -0500, Wez Furlong <kingwez@gmail.com> wrote:

the semantics of fork() and CreateProcess(), for example, are antirely different, so no. p

Try pcntl_fork() and the ext/pcntl extension (*nix only but I heard someting about cygphp which uses Cygwin and has ext/pcntl for windows). Andrey overight wrote:
