Re: [PHP-DEV] Fork() in php?
Hi, When cvs comes back up checkout the new experimental module pcntl. This is experimental so don't go using this for production just yet.

Hi! could you please send me those fork test functions ? I've written a simple NNTP-Server and the only thing missing is a fork-function. Many thanks in advance.

What do you guys think about having fork, waitpid, and signal handling available in php? I wrote a few simple fork test functions, and everything seemed to work fine. I am thinking that with sockets, shm, signals, and fork capability, there could be the possibility of someone writing daemons in php : ) Can anyone think of possible problems that could occur in supporting this functionality? If it were to be added, where should it be added? IMO this type of thing probably shouldn't exist in ext/standard.

Generally, implementing that sort of stuff within the Apache framework is a bit of asking for trouble :I Anyway, PHP really lacks of real multi-threading capabilities. Things like database connection pooling, (non-HTTP) server request handling, and GUI event processing could be properly implemented in PHP with multi-threading capabilities like the way it is done in Java, Perl, Python, etc. but can't be done right in PHP because it lacks multi-threading support. Any plans to add multi-threading capabilities to PHP? There are no plans for adding MT to PHP itself, but you do have a poor man's cooperative multi-threading through ticks. So now we have a poor man's objects and a poor man's multitasking.

Re: [PHP-DEV] Fork() in php?
I was thinking about MT in php, but the platform differences would be a nightmare. We could abstract it like perl does, though even their implementation has problems. I would like to start with process control features (fork(), signals, waitpid() etc), but I am not sure where everything should go. Should there be a /ext/process? Should signals be in a separate extension? Let me know what you guys think. -Jason - Original Message - From: Zeev Suraski [EMAIL PROTECTED] To: Stig Sæther Bakken [EMAIL PROTECTED] Cc: Manuel Lemos [EMAIL PROTECTED]; [EMAIL PROTECTED] Sent: Monday, May 21, 2001 4:33 AM Subject: Re: [PHP-DEV] Fork() in php?
