从变量中获取值，发送到php进行处理并将该值添加到mysql数据库中？

Question

i am new to php and mysql.

How can i extract a VALUE from a JAVASCRIPT VARIABLE(i set) then send it to a PHP page that can read it and process it , the PHP will then insert the value into a table in MySQL database.

var A = "somevalue"

I have been researching but none of it give me a simple and direct answer . I saw some people uses JSON(which i am unfamiliar with) to do this.

Hopes someone can give me an example of the javascript/jquery , php code to this. Thanks!

You've asked for... a lot. But, this tutorial looks like it could help you.

(FYI -- I swapped out the original tutorial for one on ibm.com. It's better but far more wordy. The original tutorial can be found here)
