You can only use pcntl_fork in CGI mode or from command-line.

To check, run: php -i | grep disable_functions If you see a list of pcntl_* functions, you'll need to edit your php.ini file (inside of XAMPP) and comment out the line disable_functi

PHP Fatal error: Call to undefined function pcntl_fork() in boris/lib/Boris.php on line 38 Would be great if this extension could be avoided, other-words it should be listed as a dependency in the README with directions on how to recompile PHP with PCNTL enabled. d11wtq commented Nov 19, 2011 Thanks for the report. This is documented in the README and is fundamental to the architecture, but I'd love to see any suggestions for a non-forking solution that is able to handle fatal errors. Boris is different to other PHP REPLs, in that it was built specifically to deal with fatal errors, which basically means each statement must be executed in a new process, in case it dies. If you don't care about the REPL quitting on fatal errors, you may be interested in https://github.com/ieure/php_repl. I'll leave this ticket open in case somebody can come up with an approach that doesn't rely on the ability to fork. michaelwills commented Jul 14, 2012 This isn't a way around it but a way to get it running if you have access to php.ini. I used this guide to get pcntl running for MAMP on OS X. http://stackoverflow.com/questions/5230255/how-to-enable-process-control-extension-pcntl-in-php-mamp d11wtq commented Jul 14, 2012 Thanks for this. The idea of the forking is fundamental to how boris deals with fatal errors (actually, you may want to try since I reverted that last commit just now, if you found boris exited on error... I just fixed an issue). I'm still keen to find a solution that works on Windows :) michaelwills commented Jul 14, 2012 Not a problem. Windows, though. Oooh boy. d11wtq commented Mar 1, 2013 I don't think the reliance on the process control functions or the posix functions can be avoided at all at this stage... Boris simply could not exist without them. I may consider writing an installer script that tries
