SV: [PHP] Pass variable to pcntl_fork child

I switched places of the parent and child code. The parent always did what it was supposed to, the child never did. /H ________________________________________ Från: Sebastian Krebs [krebs.seb@gmail.com] Skickat: den 2 juli 2014 12:29 Till: Uggla Henrik Kopia: php-general@lists.php.net Ämne: Re: [PHP] Pass variable to pcntl_fork child 2014-07-02 11:40 GMT+02:00 Uggla Henrik <Henrik.Uggla@kristianstad.se>: > Hi! > > I've tried the following code but the $call variable is not available in > the pcntl_fork child. 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.
