Dynamically changing variables inside the browser from an external source

[mmattax]

So here is the problem:

We have an openGL program running (written in C), when the user clicks an object we want to send data and view it in a webpage.

I know we can send data using the get method to a page, but how can i keep updating the values when a user clicks multiple times, and how does the browser know not to open a new page, but refresh the page showing the new values?

is there a way to do this in PHP?

in C we open the browser as the following:
[code]
ShellExecute(NULL, "open", "http://example.php?data=3;data2=4;",
                NULL, NULL, SW_SHOWNORMAL);
[/code]

how can we dynamically send data to a PHP from an outside source? is there a better way then using the get method?

php is server side -- javascript is client side.

You might just do an onClick="window.refresh()" and just have PHP build the page with current information.
