title: PECL UUID package : what purpose does it serve?
body: <p>What purpose does the <a href="http://pecl.php.net/package/uuid" rel="nofollow">PECL UUID</a> package serve?</p>
  
  <p>It does not have any documentation. If we pass a name (string) can we get UUIDs;  if we pass UUIDs, it will it return topic names. Are there any APIs for this purpose?</p>
  
  <p>Is there any alternative for creating UUIDs?</p>
