A GUI having a drwable area and a button in a frame is required. The
points colected by drawing in the drawable area needs to be stored in a
datastructure in php. can we do this using php? If so for
displaying graphics what should be done?
This GUI has to be embedded in a browser and displayed in any clients
machine. Is it possible?
PHP works serverside which means that is can do all sorts of things to a page BEFORE it is send to the browser, but not while the page is being viewed by the user.
For this drawable area you would need to find something which is able to interact, options are javascript with DHTML (taking care to be cross browser compatible), java (requires user to install java) and there are likely to be more candidates. If you take for instance javascript and DHTML for the drawable area, this script can then score the points collected in a hidden form which then can be submitted to PHP. PHP can store it in many databases or in data files.
