A quick guide on how to get pthreads (parallel threads) working with your local WAMP environment under PHP 7.1~
Current versions of pthreads wont work with PHP 7.0/7.1, because of issues they've locked use of pthreads to PHP 7.2+ (because of some security issues)
Latest versions of pthreads (3.1.6) wont work with PHP. However, version 3.1.7 beta will work with PHP 7.1/7.2.
