quick & easy question about web scrpting

Hi all,
  I learnt a bit of client side scripting(javascript), and then i noticed everybody was moving to server side scripts(php, perl etc). so i figured, why dont I.

I've started learning php(still in the basics) but i have one question that keeps bugging me...

Can Server-Side-scripting complety replace Client side??
Can i use php to do rollover effect... or can i use it to call a function after the page has loaded???

quick answer: no
serverside scripting occurs on the server, which means the user never sees what goes on until you send it to the client.  And the server never knows what is going on at the client until there is a submission/request from the client.

So, a serverside image rollover would mean that the user would have to mouseover the image, a submission would have to be made, the server would have to rewrite & redisplay the page with the new image -- totally unacceptable in today's world.

serverside scripting is used primarily for database storage and security.

you can, however, use both php & javascript on your page -- javascript for image rollovers, non-critical code, etc.  and php for whatever else
