Codes for real time multiplayer games on my website.

Hi, \r\n\r\nI need codes to interface 3 online multiplayer games to my apache server. My website is in PHP so the code has to be compatible with my website. The information on these games are as below : \r\n\r\nI have made a membership system and storing details of users in MySql database. So, i want to have a code wherein users can search for opponents by typing a name in search bar and when the opponent player is available, system can send him a new game request to either accept / decline. Once the opponent accepts the request, person who has raised the new game request should also be given an option of accept and start it. \r\n\r\nAll the above task has to be done in real time!! (without page refresh, script should run at background - can be done using ajax interface or similar data handlers)\r\n\r\nThe above work is really simple and may be ready made available, one needs to just do little bit customization as per my requirement. the main task of the project is as follow : \r\n\r\nThe games which i want to interface are as below :\r\n\r\n1) Chess\r\n2) Pinball\r\n3) Airhocky \r\n4) suggestions are accepted..\r\n\r\nThe above games has to be multiplayer real time! The main challenge is to use code (like node.js, express etc) to make these games as a real time platform between players. \r\n\r\nThe detail job will be explained in further discussions.
