title: Command Line PHP - Is it Thread Safe?
body: <p>The title says it all. </p>
  
  <p>I have read several stackoverflow questions with regards to Apache/Nginx/etc, where the question mostly focuses on thread safety between PHP and the web server. However I would just like to run PHP at the command line; in this case, is it thread safe?</p>
  
  <p>Thanks</p>
