Searching the web, I've found posts that claim that > all variables defined before pcntl_fork are copied to the child. Not directly "copied", at least not explicitely. 'pcntl_fork()' is derived from the system call 'fork()', which roughly behave like this - pause execution - Create a second (child-)process B - _clone_ the _entire_ memory used by this process A to the memory of B - resume execution So after forking the child process it is an exact clone of the parent, including all variables and stuff. The only difference is the PID and therefore (somehow) the return value of pctnl_fork(). This said: Yeah, $call should be there. Have a look at http://3v4l.org/cV73d That only works for HHVM there, but I promise you, that I had reproduced it locally with PHP5.5 ;) I've also found posts that claim that no variables are passed/copied to the > child.
