title: Using comet with PHP?
body: <p>I was thinking of implementing real time chat using a PHP backend, but I ran across this comment on a site discussing comet:</p>
  
  <blockquote>
    <p>My understanding is that PHP is a
    terrible language for Comet, because
    Comet requires you to keep a
    persistent connection open to each
    browser client. Using mod_php this
    means tying up an Apache child
    full-time for each client which
    doesn’t scale at all. The people I
    know doing Comet stuff are mostly
    using Twisted Python which is designed
    to handle hundreds or thousands of
    simultaneous connections.</p>
  </blockquote>
  
  <p>Is this true? Or is it something that can be configured around?</p>
