PHP calculations vs Javascript

[jray2003]

I have some pages that do some pretty hardcore calculations and Javascript does a good job, but if I am using PHP, are there simular methods for doing the same and redisplaying the information on the page?

Or is it better to leave the PHP pages as is and use javascript?

Thank you

Jim

One benefit of leaving them as they are is that the clients machine is having to do the work as appose to ur machine having to do the work if u use php. I would say if u don’t need to keep the information private and its working fine then don’t try to fix what isn’t broke.

To err is human, to completely mess up takes a computer.

You are talking about two completely different languages.
PHP is executed server side which means that in order to display changes on the page a redisplay is necessary. There is no altering page content with PHP once the page has left the server.
You need to take the pro and cons into consideration. With JavaScript you rely on the browser of the visitor to do the caluculations. There are people that turn JavaScript off. Maybe you want to ignore them - but you still need to make sure that your PHP code will handle submissions where no calculations were made.
DHTML is nice but doesn't work everywhere. With the PHP solution you can be 100% sure that the calculations are made.

Good points from the both of you. I still have much to consider both sides to this age old question.
