<?php /** PLEASE NOTE THIS EXAMPLE WILL CAUSE THE PROCESS TO HANG **/ $mutex = Mutex::create(true); /** You cannot use the "new" keyword, a Cond is not a PHP object **/ $cond = Cond::create(); /** The caller must lock the associated Mutex before a call to broadcast **/ var_dump(Cond::wait($cond, $mutex)); /** Always destroy Cond you have created **/ Cond::destroy($cond); Mutex::unlock($mutex); Mutex::destroy($mutex); ?>
The above example will output:
