Re: Multi-thread programming in PHP?

Forking is more like multi-processing, not threading, as a new process is started up each time you fork. Real UNIX threads are generally done using either POSIX threads (pthreads) or native threads, which can vary depending on the UNIX platform. (UNIX International threads, for instance, on Solaris. They both provide the same functionality, but pthreads are more portable since they're a POSIX standard.)
