title: what does threading mean when it comes to programming?
body: <p>i read somewhere that php has threading ability called pcntl_fork(). but i still dont get what it means? whats its purpose?</p>
  
  <p>software languages have multithreading abilities from what i understand, correct me if im wrong, that its the ability for a parent object to have children of somekind.</p>
  
  <p>thanks</p>
