title: Threads in PHP?
body: <p>I am creating a web application using zend, here I create an interface from where user-A can send email to more than one user(s) &amp; it works excellent but it slow the execution time because of which user-A wait too much for the "acknowledged response" ( which will show after the emails have sent. )</p>
  
  <p>In Java there are "Threads" by which we can perform that task (send emails) &amp; it does not slow the rest application.</p>
  
  <p>Is there any technique in PHP/Zend just like in Java by which we can divide our tasks which could take much time eg: sending emails.</p>
