Questions about active script mode

Hello, my name is Marlon. I'd like to know how to creat events in objects, for example how to insert a html button <input type="button" name="test" value="ok"> and make a "OnClick" call a php function. Andrei said me to use something like active script mode, he said me to ask about it in php-general and I think I should write to this e-mail. Thank you for helping me Marlon
