When a certain action happens on the site (built in PHP and MySQL) I would like few asynchronous things to happen on the site.
For example, when a user answers a question, uploads document, I want few asynchronous things to happen in the background such as: 1.update user's score 2. Post a message on Facebook wall 3.track users actions.
What PHP, JavaScript and MySQL technologies are best for achieving this? Please help.
I want something that MySQL triggers but wanted to happen asynchronously.
