title: TCP_NODELAY with persistent socket?
body: <p>It seems that I can either get a persistent socket connection with pfsockopen(), or get a normal socket connection with socket_connect() then using socket_set_option() to set TCP_NODELAY. But there is no way to get a persistent socket connection with TCP_NODELAY.</p>
  
  <p>Is there any way to get a persistent socket connection with TCP_NODELAY in php?</p>
