Socket Server for Flash Chat( HeLP me Please)

Hi everyone,

here’s my dilemna. I created a flash chat with php and mysql… For a while me and my pals(friends,classmates, officemate, relatives) were using it. Now for the sake of speed and technology I would like to redevelop it using PHP socket server but I don’t have an IDEA on where to start or what should I do…
I have an enovative WAMP with my PC… I don’t know if it is capable to use socket server…
I look to different PHP tutorial about socket server but I don’t understand a bit of it…
I just want to ask for guidance and technical terms about socket server, port, connections… etc (anything about socket server). and if it is possible I need a detailed explanation about it… (ex Connnection - is a blah blah blah to make blah blah blah)
Few Questions

  1. Does socket server can run on local host?
  2. Does a PHP free web host offers a socket server for PHP? (examle JanHost, deluxe host)
  3. Will i still use the echo method to fetch data to flash(XML or LoadVars)?

I’ll be right here waiting to any of your suggestions, oppinions or any violent reactions…
thanks in advance.
take care and God bless all of us…
