I just wanted to develop a web application - an online quiz, in which i need to fetch questions only once & display one at a time as the user clicks the NEXT button. But, in php ,i guess it is difficult to have the questions(data) stored & use it on the event basis(button click)(since its a mere script invocation). Whereas , in asp.net it is easily done, since the data fetched can be stored till the user ends appln. So can u suggest some ways to do it in php......? or asp.net is the only way...?
